Relief Valve

Description

The Relief Valve is a pilot-operated, diaphragm-type hydraulic control valve that protects water systems from overpressure. When upstream pressure exceeds the pilot setting, the main valve opens quickly to discharge excess pressure, then closes smoothly once pressure returns to normal. Pressure gauges on the inlet and outlet make setting and monitoring simple.

Technical Specifications:

• Pressure Class: PN10 / PN16 / PN25
• Size Range: DN50 – DN600
• Applicable Medium: Clean water, fire water
• Operating Temperature: 0°C to 80°C

Main Parts and Materials:

Key Product Features:

1. Fast Pressure Relief: Main valve responds quickly to overpressure events.
2. Adjustable Set Point: Pilot spring can be adjusted without removing the valve.
3. Smooth Closing: Controlled re-seating avoids secondary surges.
4. Self-Powered: Operates on line pressure only, no external energy.
5. Gauges Fitted: Inlet and outlet gauges for easy commissioning.

Applications:

Ideal for Pump Discharge Headers, Fire Protection Systems, Water Distribution Networks, and Pressure Boosting Stations. Specifically suited for protecting pipes and equipment from excessive pressure.
