FP 400Y-4DC-H - Pneumatic Pressure-Control Latching Deluge Valve

The BERMAD model 400Y-4DC-H is an elastomeric hydraulic, line pressure operated, deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.
The 400Y-4DC-H is activated by a pneumatic relay valve which latches the main valve open until locally reset. An integrated pressure reducing pilot valve ensures a stable and precise pre-set downstream water pressure.
The 400Y-4DC-H is suitable for open-nozzle systems with a high pressure water supply and/or relatively low flow. The pneumatic control makes the 400Y-4DC-H suitable for freezing environments and corrosive water supplies.
