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.
