FP 430-59

Pressure Relief Valve

The BERMAD Model FP 430-59 combines fire pump relief with a pre-opening feature to anticipate pump start-up surge. The valve opens fully by means of electric override upon pump start-up, and continues to function as a pressure relief valve. The valve performs reliably in high capacity
fire pump systems.

Operation

The BERMAD Models FP 430-59 and FP 730-59 combine fire pump relief with a pre-opening feature to anticipate pump start-up surge. The valve opens fully by means of electric override upon pump start-up. It continues to function as a pressure relief valve after the electric override is shut off.
