Under what conditions should a single-acting pneumatic actuator be chosen? Under what conditions should a double-acting pneumatic actuator be chosen? The difference between the two
I’m not sure what “single-acting” and “double-acting” refer to; please clarify. However, there is one point: it all relates to safety requirements imposed by manufacturing processes.
Are the terms single-acting and double-acting referring to cylinders?
Yes, it refers to single-acting cylinders and double-acting cylinders. I would like to ask under what conditions should a single-acting cylinder be chosen? Under what conditions should a double-acting cylinder be chosen? Thank you!
The choice is generally based on the process conditions; if safety requirements are present, a single-acting type is usually selected, while a double-acting type is chosen when positioning is required.
The valve is required to be in either fully open or fully closed position, and the cylinder is of single-acting type. Double-acting cylinders are used when the valve failure location remains unchanged or in applications requiring high torque.
Process requirements and fault condition selection
Valves that require instrument air supply to operate are called double-acting valves, while those that open with instrument air supply and close thanks to spring return are single-acting valves
