Constant pressure valve / back pressure valve
Constant pressure valve / back pressure valve
application
The constant pressure valve is used to maintain a constant inlet or outlet pressure; the valve body is flexible and diverse; it has ideal fluidity and cleanability; it is easy to operate, maintain and maintain; it can be directly adjusted. These applications include pasteurization, separation, filling system, bottling, filter, heat exchanger and other occasions.

working principle
The constant pressure valve is designed to maintain a stable outlet or inlet pressure application. A set of diaphragm and stem system can respond to any pressure change of the delivered product quickly and change the stem position accordingly, so as to maintain the preset pressure value. The compressed air pressure is realized by pressure regulating valve and pressure gauge. It can be used in stainless steel pipeline system. In the process pipeline, (inlet constant pressure) maintains a constant pressure at the inlet end of the valve and is used as an overflow valve. Because the inlet and the bottom of the valve body form a 90 degree angle, there is no residual liquid accumulation.
