FP 400Y-4DC - Pneumatic, Pressure-Control, On-Off Deluge Valve

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