Pressure Relief Valve with Electric Override
The BERMAD model FP 43T-59 is an elastomeric hydraulic line pressure operated relief valve, combining pressure relief with a pre-opening feature. The 43T-59 has been specifically designed for advanced fire protection systems and the latest industry standards, preventing damage from overpressure in piping systems, ensuring a preset upstream pressure limit regardless of pressure peaks and fluctuating conditions. Due to exceptional reliability and low pressure loss it is ideal for the relief of fire pump discharge.
The 43T-59 includes a pre-opening feature, whereby full opening of the valve can be achieved by electric command. This function may be used to
relieve and quell anticipated surge such as might occur during pump start-up.
After the anticipated surge has passed, signal termination returns the valve to normal pressure relief duty.
As an option the 43T-59 can be fitted with a valve position indicator that can include a limit switch suitable for Fire & Gas monitoring system
