The BERMAD model 400Y-1MC is an elastomeric, hydraulic, line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-1MC is activated by a hydraulic relay valve which latches the deluge valve open until reset locally. An integral pressure reducing pilot valve ensures a precise, preset and stable downstream system water pressure. The 400Y-1MC is suitable for systems with open nozzles with a high pressure water supply for water or foam discharge.
