Pneumatic Control Valve

“RC” pneumatic operated valve offers efficient and reliable flow control using compressed air. Ideal for automation systems, it ensures fast response and durable performance in demanding applications.

Application

Used for normally open / closed two position control of steam, liquids, air, oil brine or other non-combustible gases, heat exchange systems and as a power failure valve where tight shut off is required

Construction

Single seated, straight through globe body with high lift plug, spring loaded self adjusting packing Pneumatic actuator is equipped with reinforced diaphragm. The diaphragm is enclosed in cast iron housing with spring assembly. Valves suitable for use with control air pressure of 5 PSI to 20 PSI.
