The BERMAD model 400Y-2MC is an elastomeric, hydraulic line pressure operated deluge valve. Designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-2MC is activated by a 3-Way solenoid valve, that actuates a latching relay valve opening the main valve. Once open, the valve will not close until locally reset. An integral pressure reducing pilot ensures a stable and precise preset downstream system water pressure. The 400Y-2MC is ideal for open-nozzle systems with a high pressure water supply and is available with electric components to suit any hazardous location.
