APPLICATION
PRESSURE SUSTAINING VALVE spring type used in water systems and fire protection and fighting

DESIGN FEATURES

• Pressure-reducing valve can prevent pipeline breakage due to high-pressure
• The pressure-reducing valve uses a sub-valve (pressure-reducing pilot valve) to control the main valve. When the outlet pressure 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 maintains the outlet pressure
