Pneumatic Actuated Valves are highly reliable, safe motion control devices that rely on compressed air (or gas) to open or close the valve. These highly durable devices where rapid opening and closing of the valve is required, are well-known in industrial applications; including some with potentially hazardous environments.
The output torque of a Spring Return Actuator is not consistent but decreasing. This is due to the action of the springs. When compressed by the air pushing out the pistons, they accumulate energy. Which will be available in a decreasing way during the clockwise rotation inversion.
The torque of a Double Acting Actuator remains consistent throughout the complete action.
Pneumatic Actuated Valves are versatile in their applications and environments. They are considered when low maintenance is preferred.
