Pneumatic Control Valve

Description

This valve is a useful device to control flow on the set point range in the lines. The device size is DN15 to DN150 or 1/2″ to 6″. Its nominal pressure is PN16 to PN40 and working Class is 150/300.  Its maximum temperature is 350°c or 662° F. This device is made base on DIN and ANSI standards. PCV 24-11 is used for various industrial and special sites which have compressed air and also steam, liquid or non-flammable gases lines.

Control valve, type 24-11, can control the output discharge by using of a compressed air force and a diaphragm actuator.  This valve can be normally open or closed and this feature is occurred by changing of springs positions inside actuator. The attached shaft is gradually moved, by changing the compressed air volume, and it will cause to change also the distance between seat and plug. In this way, the flow rate of fluid can be controlled. Air pressure inside the actuator can be supplied from regulators and I/P positioners through 4…20 mA.
