Pressure Control and Check Valve
The BERMAD model 42T-20 is an elastomeric, hydraulically operated, self actuated automatic pressure control valve with a check valve feature. This valve is designed for advanced fire protection systems in accordance with the NFPA-13 and NFPA-20 guidelines.
This valve will reduce a high upstream pressure to a low and stable designed system pressure, the check feature makes this valve ideal for fire system pressure control between floors in high rise buildings.
As a fire pump surge control valve the 42T-20 will prevent pump water surge pressure spikes, typically caused by the accelerated water flow during fire pump start-up.
In addition this valve will significantly reduce pump start negative suction pressure, preventing pump cavitation damage.
Due to exceptional reliability, safe actuation and low head loss, the 42T-20 is highly suited for fire pump discharge pressure control applications.
