Our pneumatic actuator series 2000 (which is a direct replacement for our previous PA-1000 actuator) is a high quality, durable housing that contains a powerful actuator capable of turning the biggest valves in the market.  This series of actuators (in spring return operation and double acting) are capable of being fail to open and fail to close.  Using compressed filtered air, not necessarily lubricated is recommended.  With a brand new, compact design - this Spring Return/Direct Acting pneumatic actuator is ideal for butterfly valve and ball valve automation.

manual icon copySpring Return Actuation Configuration

CCW - (Counter Clock Wise) Air is supplied to Port A forcing the pistons away from each other (towards ends), rotating the drive pinion counter-clockwise and exhausting air out of Port B.

CW - (Clock Wise) Air is supplied to Port B forcing the pistons toward each other (towards center), rotating the drive pinion clockwise and exhausting air out of Port A.

Double Acting Actuation Configuration

Fail CCW - (Counter Clock Wise) Air is supplied to Port A forcing the pistons away from each other (towards ends), rotating the drive pinion counter-clockwise, compressing the springs and exhausting air out of Port B.

Fail CW - (Clock Wise) Air failure (loss of pressure) allows the compressed springs to force the pistons toward each other (towards center), rotating the drive pinion clockwise and exhausting air out of Port A.
