BERMAD Fire Protection 400Y Series Pressure Reducing Valve Model 42T The BERMAD model 42T is an elastomeric, line pressure driven pilot operated pressure control valve. 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. ISO 9001-2000 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. As an option the 42T can be fitted with a valve position indicator that can include a limit switch suitable for Fire & Gas monitoring systems.

BERMAD Fire Protection 400Y Series Valve Closed (non-flow conditions) Valve Open (flow condition) 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 pilot adjusting screw [5]. The valve operates under both flow and static conditions. The pressure-reducing pilot valve [4] senses changes in outlet pressure [6] and modulates the control valve to maintain the preset outlet pressure. When outlet pressure rises above the preset pressure...

BERMAD Fire Protection 400Y Series System Installation A typical installation of the BERMAD model 42T features a pilot valve for the automatic stable and accurate reduction of water pressure from a high upstream value to a preset lower downstream value, regardless of fluctuating upstream pressure or flow. A unique actuator design ensures quick and smooth valve action. Installed singly, the 42T provides a standard pressure-reducing system. Installed in parallel, two 42T valves provide high flow rates, redundancy, and zero downtime for maintenance. Installed in series, two 42T valves can...
