These actuators, which use compressed air as their propellant, can store energy in the spring while it moves valves.

Instrument air low pressure powered piston type actuators are suitable to operate any linear or quarter turn valves. Their reliable high efficiency design makes them ideal for Upstream FPSO units and Oil fields, Midstream LNG, Downstream refineries.

• Pneumatic Actuators are designed for ON-OFF or modulating control of Quarter-turn ball, butterfly, plug or damper style valves.
• The PRSS-RPSD series are heavy duty high performance design actuators.
• These actuators are popular for their high resistance and durability, in consequence, reduction of maintenance cost in production line.
• It has two types:

 1/1.RPSS (Spring Return), RPSD (Double Acting)

1/2. RPRS (Spring Return), RPRD (Double Acting)

*1/1. RPSS (Spring Return), RPSD (Double Acting)
