Operatiing principles

Constant pressure valve operated by compressed air, automatically run without sensor on piping system ot other auxiliary instruments, and only one compressed air pressure regulating valve that maintains perssure stability can be realized the normal work of the valve.
Diaphragm slice and valve rod can be fit to transport product an pressure changes to make a quick response, and the corresponding change the valve stem position, in order to continue to keep the preset pressure vavle.
Constant pressure valve - V: inlet pressure constant , in conveying medium pressure higher than the set pressure under the condition of the valve opens, the transmission medium pressure decreases flow has become, conveying medium pressure is insufficient valve closed.
Constant pressure valve - A: outlet pressure constant, when transmitting medium pressure is higher than the set perssure under the condition of the valve will be closed, conveying medium pressure decreasees flow changes, conveying medium pressure is insufficient valve opens.

Product application

Applications

This valve has two styles:eletric-pneumatic control valve and manual control valve,used in automatic control system to control pressure,capacity,temperaure and tank level.
