The 43T prevents damage due to over-pressure in piping systems by 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.
