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 optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems. The 400Y-1MC is ideal for systems with open nozzles with a high pressure water supply for water or foam discharge.

A typical installation of the BERMAD model 400Y-1MC features automatic actuation via a hydraulic universal relay valve, triggered by a fusible plug loop.
A pressure reducing pilot valve integrated in the trim ensures a precise and stable pre-set downstream pressure.
When fitted with a limit switch the valve can send a feedback signal to a remote valve position monitoring system.
