Donjoy Constant Pressure Valve with two types
● V type (inlet constant pressure): This is meant to maintain constant pressure on the valve inlet. This kind of design is mostly applied to the back of heat exchanger.
● A type (outlet constant pressure): This maintains constant pressure on the outlet. This type of design is mostly used as the front of a filling machine.

 

Constant Pressure Valve Working Principle

Constant pressure valve operated by compressed air, automatically run without a sensor on piping system, only by compressed air pressure regulating valve that maintains pressure stability can be realized the normal work of the valve.
The membrane and valve rod can be fit to any pressure changes to make a quick response, and the corresponding change the valve stem position,in order to continue to keep the preset pressure value.

The constant pressure valve- V type: inlet pressure constant, in transporting medium pressure higher than the set pressure under the condition of the valve opens, the transmission medium pressure decrease flow has become, transporting medium pressure is insufficient valve closed.

The Constant Pressure Valve- A type: outlet pressure constant, when transporting medium pressure higher than the set pressure under the condition of the valve will be closed, transporting medium pressure decreases flow changes, transporting medium pressure is insufficient valve opens.
