Tips: What should be considered when selecting a pneumatic valve actuator?

Air source pressure of the actuator.
The operating torque of the valve plus the safety factor recommended by the manufacturer, and at the same time, according to the application of the valve, operating temperature, operating frequency, pipeline and pressure difference, flowing medium (lubrication, drying, mud), many factors affect the operating torque.
Type of pneumatic actuator: double-acting or single-acting (spring return) and output torque under a certain air source or output torque under rated voltage, too small to rotate, too large valve life is not long, generally leave enough 30 % safety factor.

Existing reviews of Double Acting Pneumatic Valve Actuator, 50mm Bore Size

Reliable performance with solid build quality

I’ve been using this pneumatic valve actuator to control a ball valve in our compressed air system, and it has been very dependable. The double-acting mechanism operates smoothly, providing consistent opening and closing without hesitation. It works efficiently within the 2.5–8 bar pressure range, and the maximum 10 bar capacity gives extra confidence during operation. The aluminum alloy housing keeps it lightweight yet durable, making installation simple and reducing strain on the valve assembly.
