Nowadays safety systems saturate the industrial substructure, spreading protective influence all the way to an industry’s end result. Modern safety structures minimize risk with effective enhancements that commonly increase dependability, proficiency and viability.
Although safeguards are implemented numerous times over while constructing electrically automated flow systems, overcurrent can still be crippling if fuses are inaccurately rated for the application. In this editorial I will offer you the information necessary to prevent a potential halt of production or in some applications catastrophic failure. The job of a fuse is to shield not only the equipment itself but also employees from severe impairment resulting in repairing or replacing equipment and more importantly injury to operators once an overcurrent circumstance takes place.
The likelihood of a motor failure without external causes is very rare. Motor failure rates from our experience are less than 1 in 10,000 motors.
Based on the statistical likelihood of an actual faulty motor you need to be skeptical of all claims in regards to a “faulty motor” especially when the actuator is still under the factory warranty. Even if the motor has failed, odds are that there is some other underlying issue or external cause that has led to a motor failure.
Due to the nature and physical properties of anodic coatings, anodized aluminum products and components are used in thousands of commercial and consumer food processing applications, including:
- Automatic Icemakers
- Display Cases
- Traditional and Deep-Dish Pizza Pans
- Bake Ware
- Gourmet Cookware
- Automated Packaging Equipment
- Food Processing Equipment
This is just a small sample of food-related products made, in whole or part, of anodized aluminum.
- Electric actuators: using either one-phase or three-phase power (depending on the size of the application and the availability in site) to energized a set of gears, operating any type of valve.
- Pneumatic or hydraulic actuators: using either a rack & pinion or a scotch yoke device for moving a rotary valve.
Plant engineers are tasked with a vital job: equipping their plants with the most reliable, high quality and cost-effective electric actuators for their applications within their assigned budget. But picking the right electric actuator can be a difficult procedure that can have a big influence on plant production and therefore revenue.
If an electric actuator fails in process applications, end users lose valuable time and money to replace this electric actuator. In some circumstances, complete section of a plant may need to be shut down for the repair, and unforeseen stoppage is always expensive. That’s why many engineers and purchasing agents choose electric actuators based on specification, performance (past and actual), quality and of course cost. When making a selection, decision makers must be able to evaluate all options for the plant and consider both short-and long-term effects.
This decision will only get more difficult as the industry changes so fast. Estimations by VMA and other industry organizations forecast that demand for industrial electric actuators in the US will rise over the next years with the increase for control valves.
Significant global energy demand growth and rising living standards in China, India, and the Middle East, coupled with technological breakthroughs continue to alter the fundamentals of oil & gas production, creating unprecedented opportunities for U.S. oil & gas equipment exporters in the near-term. New technologies have allowed the development of oil & gas resources that were previously considered uneconomic. The dramatic changes in the sector offer new commercial opportunities for U.S. oil & gas equipment manufacturers to penetrate new markets, gain share in existing markets, and revisit previously declining or over-regulated markets despite declining global oil and gas prices. These fast-developing trends also present an important opportunity for U.S. oil & gas equipment sales, especially valves and actuators, through focused export promotion efforts.
Over the years and across the globe, Earth Day has become one of the most widely celebrated environmental events. The day is about appreciating the uniqueness of our planet and the phenomenal biodiversity it offers to us. This year Earth Day will be celebrated on April 22nd, 2015. On this day people all over the country, and globe, will be participating in events that ensure our globe is kept sustainable and our environment is clean. Actions such as planting trees and saplings, removing and collecting garbage, encouraging recycling, cleaning roads, cleaning up parks and streams, and even educating others are things that occur on this very day.
It is increasingly evident the importance actuators have in the oil and gas industry. Actuators play a vital role in virtually every aspect of operations at every refinery. With the recent decline of gas prices in the United States, it is important to understand what this means for the oil and gas industry as well as for other flourishing American industries depending on the oil and gas.
A good analogy for initially understanding duty cycle can start with the idea of riding a bicycle. You peddle (period of energy exertion) and then coast (continuemoving from your own forwardforce, without the addition of any power). As you slow down (due to wind resistance, road friction, or road terrain) you peddle to speed up and then coast again.
Nowadays wind turbines play a larger role in the power generation combination for the USA. Every day, more and more turbines are being installed across states and the country. Although valves don’t play an important part in the wind energy generation, actuators are a much more significant element in the operation of wind turbines.
This installation and maintenance manual explains how to install and maintain electric actuators. Information on installation, disassembly, reassembly, operation, troubleshoot and parts is provided. Every actuators manufacturer should provide an installation and maintenance manual to its customer but in some cases, they are incomplete or don’t even make it to the end-user on the field. So here is a somehow generic installation, operation and maintenance manual that could be used for most electric actuators on the market.
“Let’s create a night shift!”
Anyone working for a growing manufacturer has heard that before. Sounds easy and simple: hire a few more workers, no need for costly overtime anymore, and increase production to meet customer needs… Really?!
Not that long ago, the only way a manufacturer could build a prototype was to spend a whole lot of money in R&D and then even more into castings or moldings. Now, however, building a prototype can be as inexpensive and simple as hitting the “print” icon on your computer.
Electric actuators have been used in many industries for tens of years but their positive impact on the environment is often disregarded. Nowadays many end-users and contractors are still choosing hydraulic or pneumatic systems over electric systems. Electric actuators can do the same job with more environmental benefits. Using electric actuators not only reduce negative environmental impact, they require less energy to function and cut down on operating costs.
With Baby Boomers coming close to retiring or already retired, manufacturers must do all they can to keep employees and knowledge inside the company. Labor turnover can be costly and is very negative to manufacturing businesses, which depend on well-trained personnel and steady production. Here’s what you, we manufacturers, need to ask the workforce.
A growth in oil exploration activities, investments in new refineries, and modernization of existing facilities will stimulate the use of valves and actuators, particularly in emerging markets such as Latin America and Africa. In Latin America, demand from the offshore oil and gas industry is expected to fuel the valves and actuators market. In addition to demand from emerging economies, control valve manufacturers will find growth opportunities in North America and Europe due to end-user preference for greater process automation.
PennEast Pipeline Company publicized their plan to build a 100-mile pipeline to bring natural gas extracted in the Marcellus Shale region to the states of Pennsylvania and New Jersey.
To help recognize National Pollution Prevention Week, KPPC presented its 2013 Environmental Sustainability (ES) award to Indelac Controls in Florence Kentucky on September 10. KPPC has presented the ES awards in conjunction with National Pollution Prevention (P2) Week since 2009 to recognize Kentucky companies that have demonstrated a commitment to the principles of sustainability.
In the search for oil and natural gas under the ocean, three general types of drilling rigs are used. A “jackup” drilling rig is a floating barge with drilling equipment on its deck and long support legs, and is used in shallow waters up to 300 feet (90 meters). A semi-submersible is the most common type of offshore drilling rig, used for drilling in waters more than 300 feet (90 meters) deep. Semi-submersibles are floating vessels supported on large pontoon-like structures submerged below the sea surface. Semisubmersibles are attached to the ocean floor using strong chains or wire cables. Farther offshore, specially designed rigs mounted on ships can drill a well in waters over 10,000 feet (3050 meters) deep. These rigs float and can be attached to the ocean bottom using traditional mooring and anchoring systems or they maintain their position by using thrusters to counteract winds, waves and currents.
There are more than 180,000 miles of liquid petroleum pipelines across the United States. They connect extracting areas to refineries and petrochemical plants as well as delivering the refined product to American consumers for personal and business uses.
The ethanol blending process is a critical part of a gasoline terminal operation and has a significant impact on product quality, meeting environmental regulations and profitability. Optimizing the process is very important, but does present some control challenges. For example, thermal expansion of gasoline and ethanol do not occur at the same rate, and the blended mixture has to be isolated from water due ethanol’s miscibility in water. For these reasons, many terminals blend in real-time while loading directly into the tanker trucks, but, the required control strategy doesn't allow much room for problems or inconsistencies. Getting the needed control begins with accurate, consistent and reliable valve actuation.
Actuators are a small part relative to the overall systems they live in. Many of these devices weigh in at only ten or twenty pounds. But they are a small component that plays a crucial role: When it’s time for a valve or damper to close, for a flow to stop, or for a system to shut down, the actuator absolutely must work, to prevent catastrophe. Failure is not an option.
Developing a new actuator product can easily take two years and over a million dollars. Actuators are designed and manufactured to the most exact tolerances possible, and every product must be tested and produced with the utmost care. A failure could result in a catastrophic spill, explosion, chemical release, environmental contamination, power loss, property damage, injury, or even loss of life. Actuators trigger immediate shutdown and containment in case of an incident.
"Digital Fieldbus Technologies Catch Up to Valve Actuators and Positioners"
Fieldbus is the name of a family of industrial computer network protocols used for real-time distributed control, standardized as IEC 61158.
Advanced digital fieldbus technology has been successfully used in oil and gas, petrochemical, pulp and paper, and other industries. This technology has also been implemented increasingly in the fossil fuel power industry.
Actuators can have many different sizes, shapes and functions, but all of them require some sort of input power to move the valve or the damper they are mounted on. On this blog, we have talked about many different input sources in the past, from compressed air for pneumatic actuators to electricity for electric actuators but rarely about the first source ever used: manual input. Nowadays this source of power is not as used as before but it can still be a viable option in some specific situations.
Since the middle of the 20th century, to regulate the level and the flow of water of a river, many cities use sluice, knife or slide gates. They can be essential in protecting against flooding in times of non-discontinuing precipitations but also in times of drought by regulating the flow and keeping it at a minimum level. In 1910, if the Seine, river crossing “The City of Lights”, was equipped with sluice gates automated with electric actuators, could the city have prevented The Great Flood?
There are many dangers when extracting, transporting and refining oil & gas or any other dangerous materials. Two of the major ones are fires and explosions. It can potentially harm people, destroy installations, as well as create environmental catastrophes. An efficient way to lower the possible damages is to protect the equipments that control the flow of hazardous materials. Appropriate fire protection for the valves and especially for the actuators is critical in case of emergency to maintain control over the automation process and contain an incident.
The common idea of an automated valve is a large valve with a heavy-duty actuator, typically powered by a three-phase electrical supply. Nevertheless, many industrial processes require smaller valves, and those valves often call for compact electric actuators for either isolating or modulating applications. Consequently, the number of these compact actuators is increasing gradually in recent years.
Entire actuator or automation package replacement can be expensive and time-consuming. In-field repair and modification can allow to resume operations in the shortest time and at the lowest expense. The 5 criteria below are crucial to selecting an industrial valve actuator repair company that will minimize downtime and restart production process quickly.
Continued advancements in technology have undoubtedly touched almost every aspect of human lives, giving us more convenience, variety and function than ever before. Recently, even pumps and industrial valves systems have been revolutionized, making them more flexible and effective.
Lean manufacturing is based on finding efficiencies and removing wasteful steps that don't add value to the product. No need to reduce quality, the cuts are a result of finding better, more efficient ways of accomplishing the same tasks. Henry Ford is considered the first one to implement Lean Manufacturing. He applied the concept of "continuous flow", keeping production standards extremely tight, so each stage of the process fitted together perfectly with the next one. This led to very little waste. In terms of electric actuators, here are 4 questions to help you think about cutting down waste and improving production.
Here are 5 arguments showing why, despite more than 5 years of debating and controversy and the project still not being approved, Keystone XL remains in the best interest of the U.S.
There are more than 4,300 years between the invention of a threaded screw and the modern industrial threaded screw as it is known nowadays. That's a long period of time since the threaded screw is something the majority of the world doesn't spend much time thinking about. Every time you turn a screwdriver in the process of making something, you can thank thousands of years of innovation. And the next time you use an object (car, washer, TV…), whether screws were used to manufacture the object itself or used in the machinery that made that object, you will think about this article.

Are you still using hydraulic and pneumatic actuators? You may want to read on and reconsider your decision. Electric actuators are continually gaining popularity over their hydraulic and pneumatic counterparts, but there are those who still think that electric actuators aren’t up to the job. There are some myths that are going around, and this article's goal is to expose them.
Here is a guide on how to fine-tune a Modulating Electric Actuator AC & DC Controls. The following instructions are a step by step manual for an easy and smooth field calibration.
If you need an answer to the following questions, you are looking in the right place:
- What are the main components of an electric actuator?
- How is a two-position electric actuator wired?
- Open, Close... How does it really work?
- What if the valve is not completely opened or closed?
- Do you need to apply constant power to an electric actuator?
- Do you really need a start capacitor and a brake on an electric actuator?
The suitability of a valve for a specific application is defined by the materials used in relation to the transported fluid as well as its mechanical design. Here is Indelac Valve Selection Guide.
Here at Indelac Controls, we strive to innovate and always offer new reliable products. In this effort, we have come up with our own NEMA 6P Electric Actuator. Here is how the testing happened and the results.
In an emergency situation such a fire inside rail or road tunnels, or even underground passenger platforms, electric motor operated dampers in the ventilation system can act to clear smoke from the structure as well as to suppress spreading of the fire. Most electric actuators that operate these dampers are required to be "failsafe". They are equipped with mechanical springs that open (or close) the damper upon sudden loss of power. These electric spring return actuators automating dampers must also be able to work under extreme temperatures.
An Actuator is a mechanical device that converts energy, here electricity, into motion. It can be a linear motion (one direction) or a rotary motion (circular motion).
Unwanted condensation in/on electrical goods can have severe consequences. Metal parts, even stored in warehouses can corrode or suffer surface damage as a result of condensation. Inside an actuator enclosure it can damage critical components that impair product quality or productivity of the equipment, possibly leading to a breakdown. How can such a potential problem be solved?
The following list of valve actuator terms may assisted when explaining your automation needs, to help us better serve you.
Lack of knowledge about torque can often mislead buyers to inaccurate choices when choosing an actuator for their automation package. Here is a clear definition of what actuator torque is.
Electric rotary actuators are basically geared motors with a variety of electrical accessories (limit switches, heater, circuit boards) that may be specified to meet the exact valve automation requirements of a process control system. As an electrical device it is housed in an enclosure designed for specific area classifications (NEMA Rating).
To ensure automated valve performance in today’s sophisticated process control systems it is essential to develop a complete specification for each of the elements in the control package.
As the process industry continues to achieve more efficient and productive plant design, plant engineers and technicians are faced, almost daily, with new equipment designs and applications. One product, a valve actuator, may be described by some as simply a black box, having an input (power supply or signal), an output (torque), and a mechanism or circuitry to operate a valve. Those who select control valves will quickly see that a variety of valve actuators are available to meet most individual or plant wide valve automation requirements. In order to make the best technical and economical choice, an engineer must know the factors that are most important for the selection of actuators for plant wide valve automation. Where the quality of a valve depends on the mechanical design, the metallurgy, and the machining, its performance in the control loop is often dictated by the actuator.
What’s a Thermal Actuator?
Actuators are simply devices used to transform energy into motion. A thermal actuator is a type of non-electric motor made of components such as a piston and a thermal sensitive material capable of producing linear motion in response to temperature changes.
Picking the right Electric Actuator for a valve is not that easy. Industry buyers ask yourselves these 24 questions before choosing your valve automation solution.
"Do we do it the old, reliable way, or do we challenge ourselves to demonstrate new technology and use continuous improvement?" That was Kevin Dahm's question.
Dahm, a principal engineer in the Major Enterprise Projects (MEP) division at DTE Energy (www.dteenergy.com), recently faced this issue while adding control room architecture to the flue gas desulfurization (FGD) equipment and controls on each of the four 800-megawatt, coal-fired units at its Monroe Power Plant near Detroit. The FGD process scrubs power plant emissions by using limestone slurry as a reagent to convert SO2 in the flue gas to a gypsum byproduct, which is then available for use in drywall, instead of ending up as landfill.

Condensation + Electric Actuators = Issues
However, if I told you I had a friend call me this week and tell me that their climate has been very hot and dry for quite some time but they were experiencing a water problem with one of their electric actuators. He told me there was so much water in the electric actuator enclosure he literally had to pour the water out of his actuator.
Fail-safe Actuator, that simple short phrase commands many different visions of various types of actuators. If you Google Failsafe Actuator you would get 1,910,000 results. If one is going to use a fail-safe actuator in their application you might say they have their work cut out for them selecting the right actuator for their application. With so many Google results the first logical question would be; what is a fail-safe actuator?
Precise actuator sizing and selection is a fundamental factor to consider while deciding on a valve automation solution. Making the correct decision warrants dependability and enduring productivity, especially for applications in unforgiving environments. Components such as seal life, side loading, and working conditions will ultimately drive design standards that will determine MTBF (mean time between failures).
