Egret series water regulating valve is a kind of condensing pressure regulating valve, which is installed in the cooling water pipeline of the condenser and maintains a constant condensing pressure by automatically adjusting the cooling water flow rate.

EGWV series water valves are used in refrigeration system.
It keeps the pressure in a certain value to maintain normal running and increase refrigeration effect.
Also it can save water by cooling water circulation.
EGWV series water valves are usually installed on the inlet of condenser
It can regulate the flow of cooling water according to the change of condensing pressure.
When the condensing pressure of the refrigeration system rises, the valve automatically opens wider to increase the flow of cooling water to accelerate heat dissipation and reduce the pressure. When the pressure is lower than the set value, the valve is closed to reduce the water flow, thereby maintaining a stable pressure.
It is also called condensing pressure regulators, installed in condenser water inlet, to regulate cooling water flow according to condensing pressure variation.
To ensure the stable cycle of refrigeration, we use water regulating valve to control the condensing valve in a normal standard.
It opens and closes the valve to control the cooling water flow.
The compressor discharge pressure signal to stabilize the condensing pressure.
