The BERMAD Model 400Y-6D is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-6D is activated by a 3-Way solenoid valve which in turn activates a pneumatic relay valve. It can also be activated by a pressure decrease in the pneumatic pilot line. Opening or closing of the valve can be performed remotely. The 400Y-6D is ideal for open-nozzle systems and is available with electrical components to suit any hazardous location.
