Three-Way Pneumatic Control Valves

Three-way pneumatic control valve uses cylindrical thin window shaped valve guiding, which is different from the guide bushing of plunger valve. Equipped with multi-spring actuator makes it have the advantages of simple structure, light weight, small volume, ease of dismounting etc.. Three-way pneumatic control valve is widely used to accurately control gases, liquids and other media.Process parameters such as pressure, flow, temperature and liquid level maintain a set point. Three-way pneumatic control valve is suitable for a occasion that the fluid is divided into two way to outflow through a three-way or two fluid is synthesized into a fluid through a thee-way valve

Product features:

- Action orientation of a fluid on the spool is in the state of open so that the valve can work stably.

- The side of spool also generates a guiding role with the internal surface of valve seat surface in addition to guide bushing in the bonnet.

-  Actuator with multi-spring structure reduce by 30% height and 30% weight.
