3 Inch Constant Pressure Valve with EPDM+PTFE Gaskets
Applications:
The valve is a sanitary constant pressure valve which can be used in food-processing, beverage, biopharmaceutical.
It has two kinds of keeping constant pressure:
V type (
inlet constant pressure); maintain constant pressure at the valve inlet. Such desifn is specially applied at the back of heat-exchanger. It is used as safety valve.
A type
(outlet constant pressure); maintain constant pressure at the outlet. Such design is used as the front of filling machine and bottle filling machine.

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.
