The BERMAD Model 400Y-6DC is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y 6DC is activated by a fall in pneumatic pressure of the pilot line or by an electric signal to a 3 way solenoid valve. The 400Y 6DC can also be activated remotely either pneumatically or electrically. When open an integrated pressure reducing pilot valve regulates the main valve to maintain a precise, stable, pre-set downstream pressure. Opening or closing of the valve can be performed remotely. The 400Y-6DC is ideal for open-nozzle systems with a high pressure water supply. It is available with electrical components to suit any hazardous location.
