How to Decide Between Pneumatic and Electric Actuators

Pneumatic actuators come in many design types, but all share the same need for basic understanding of how their torque operates a valve. Accuracy is critical regardless of who sizes it. Incorrectly sizing an actuator can lead to a multitude of problems. Sometimes an actuator will have enough torque to open a valve but not enough to close it.

Sometimes a valve may get stuck in mid-stroke. Other times, an actuator may provide so much torque that it damages the stem of the valve which it is operating. Users need to consider:. Different valve types have different torque signatures. For example, a metal seated butterfly valve requires a large amount of torque to break or close and very little torque while traveling between the two positions.

A metal seated ball valve requires a large amount of torque to open or close but also has an elevated torque requirement while traveling. Most manufacturers will publish a minimum torque required at a given operating pressure to open the valve in water service.

In most instances, closing torque is the same as opening torque. Others will only publish the torque required at maximum operating conditions. Rarely do valve manufacturers publish the running torque of their valve. In any case, you may not have enough information to properly size an actuator even with the published torques based on what type of actuator you chose.

Be very careful to also consider what media is flowing through the valve. Some services will increase the torque required to operate a valve. Also, consider if your customer requires you to add a safety factor to the valve torque prior to sizing an actuator. Actuator design will affect the sizing. Rack and pinion actuators produce a constant torque output throughout the stroke.

Scotch yoke actuators produce reduced torque in its mid-stroke. A spring return actuator has reduced torque the further it is operated because it is overcoming internal springs that are used to return the actuator to its initial position once air is removed.

Just because their compressor is set at a certain pressure does not mean they have the same pressure at the valve.

Tips on sizing pneumatic actuators Pneumatic actuators come in many design types, but all share the same need for basic understanding of how their torque operates a valve. Understanding torque requirements and how to size an actuator are crucial.

Users need to consider: Break torque Running torque Closing torque Maximum shaft torque. Some basic valve definitions users need to know are: Break torque, also known as opening torque.

This is the amount of torque required to start the movement of a valve from the closed position. Running torque, also known as mid-stroke torque.

This is the amount of torque required to maintain movement of the valve between open and closed positions. Seating Torque, also known as closing torque. This is the amount of torque required to seat a valve into its closed position.

Maximum allowable stem torque MAST , which is the torque required to permanently deform or break the valve stem. Modulating service, also known as throttling service.

Modulating valves are rarely fully open or fully closed. Modulating valves usually require more torque than simple on-off valves. On-off service is for a valve that is used for shut-off. It will either be used fully closed or fully open and will not stop during mid-stroke.

It is an actuator with internal spring that will return the valve to the initial position on loss of air supply. Double acting: Air is required to open or close the actuator. The actuator will fail in place with the loss of air supply.

Also known as Direct Acting. Start of AirThe amount of torque produced by the air supply to the actuator to start a movement from the normal position. End of spring is the amount of torque that the internal springs provide in the normal position with all air pressure removed. In this position, the spring is considered to be in its relaxed position with a pre-load. Depending on actuator type, this may be the same value as end of air. Other times it may be the mid-stroke position.

This is the force the actuator will supply as the air is removed and the actuator reverses directions from its end of travel position. Related Articles Take a different perspective with unexpected downtime Four aspects of good control panel design Storing pneumatic energy for emergency situations.

Pneumatic actuators use air power to produce rotary and linear motion. In the broadest sense, an air cylinder is a pneumatic actuator. For the purpose of this article, pneumatic actuators that are intended to produce rotary motion for operating valves , for automating manufacturing, for clamping work, etc.

The debate surrounding the pros and cons of electric and pneumatic actuators has been raging for years and still no easy answer exists. Here, with the help of Bimba Manufacturing, we focus on the core differentiators to help narrow your decision. If there is any significant performance differentiator, it is that electric actuators are better known for their high levels of precision. Though this is not to say pneumatic actuators cannot deliver very precise motion. Again, the issue here revolves around how much precision you really need. For help on this issue, we referred to information from Bob Kral at Bimba Manufacturing Company, a supplier of pneumatic, electric and hydraulic actuators.

Pneumatic Actuators

Pneumatic or electric? The merits of each have long been subject to discussion, but a fair amount of confusion continues to exist about which makes more sense for what. Or, perhaps you are thinking about building a new machine with pneumatics because 30 electric actuators are far too expensive. Make the wrong decision in either case and you could waste tens of thousands of dollars a year.
