Features

Pressure reducing valve can prevent breakage due the high pressure
Pressure reducing valve is installed in water supply pipeline and maintains the setting outlet pressure in main valve, regardless of the different inlet pressure
Pressured reducing valve can be instelled in water supply, air conditioning and fire control systems to maintain the setting outlet pressure
The pressure reducing valve uses a sub-valve (pressure reducing pilot valve) to control the main valve. When the outlet pressue reaches the setting range of pressure reducing pilot valve, the pilot valve will automatically sense the outlet pressure and adjust the pressure of the back pressure chamber in the main valve, so the valve gate can be opened and consequently maintaines the outlet pressure.
The pressure meter on the pilot valve shows the outlet pressure. When the outlet opens, the valve of the pressure meter is lower.
When the outlet is used for large flow and the gate generates quick - close motion, the pilot valve will slowly respond to the main valve to close the gae. Under this situation, the outlet pressure gets a little higher, and a tiny pressure reducing valve can be added.
