FP 43T - Pressure Relief Valve

The BERMAD model 43T is an elastomeric, pilot operated, pressure-relief valve. Designed specifically for advanced fire protection systems and the latest industry standards. The 43T prevents damage from over-pressure in piping systems, maintaining a preset upstream pressure limit regardless of pressure peaks and fluctuating conditions. Due to exceptional reliability and low head loss, it is ideal for relief of fire pump discharge. The 43T dependably relieves excess system pressure to sump or atmosphere, meeting all NFPA, UL, and FM requirements for fire pump service. The 43T is also well-suited for maintaining foam concentrate discharge pressure for a balanced proportioning system.
