Bermad FP42T Pressure Reducing Valve



Bermad FP42T Pressure Reducing Valve

The BERMAD model 42T is an elastomeric, line pressure driven pilot operated pressure control valve. It is designed specifically for advanced fire protection systems and the latest industry standards. The 42T reduces high upstream pressure to a precise, preset, stable downstream pressure. Due to its exceptional reliability and low head loss, the 42T is ideal for control of fire pump discharge. It is also well-suited to prevent over-pressure in sprinklers, hose stations, and other discharge devices.

The BERMAD Model 42T pressure control valve, reduces water pressure automatically and accurately from a high inlet pressure to a lower, preset outlet pressure. The outlet set pressure can be adjusted by way of the pilotadjusting screw. The valve operates under both flow and static conditions. The pressure-reducing pilot valve senses changes in outlet pressure and modulates the control valve to maintain the preset outlet pressure. When outlet pressure rises above the preset pressure , the pilot valve throttles, enabling pressure to accumulate in the control chamber, this causes the control valve to close further and reduce outlet pressure. When outlet pressure falls, the pilot valve opens wider, releasing pressure from the control chamber. This causes the control valve to open wider and increase outlet pressure. An integral restrictor controls the valve’s closing speed.

For valve sizes 12, 14 & 16” an adjustable needle valve is provided.
