The BERMAD FP 730-UF relief valve is a reliable hydraulic control unit designed to maintain stable pressure and protect fire protection systems from overload. The valve responds quickly to pressure changes, effectively relieves excess pressure and ensures safe system operation even under heavy loads.
Main advantages:
- Highly reliable and leak-proof - the unique double chamber hydraulic design ensures precise control and leak-free operation.
- Water-efficient body - straight flow path with no restrictions minimises pressure loss.
- Easy maintenance - all components are accessible for inspection and service without disassembly.
- Resistant to aggressive environments - available for seawater and chemical applications.
- UL and FM certification - full compliance with NFPA-20 standards for fire pumping systems.

How it works:
When the pressure in the system exceeds the set point, the BERMAD fire system hydraulic valve automatically opens, discharging the excess water into a drain or tank. This prevents the operating pressure from exceeding the set point and extends the service life of all equipment.
