Pneumatic Pressure Control Deluge Valve with Local Reset
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 latching pneumatic relay valve that latches the main valve open until locally reset. An integrated pressure reducing pilot valve ensures a stable and precise pre-set downstream water pressure.
An optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems.
The 400Y-4DC-H is ideal 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.
