The BERMAD model 400Y-3DC is an elastomeric, hydraulic, line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.

The 400Y-3DC is activated by a 3-way solenoid valve, by which opening and closing of the deluge valve may be controlled remotely.

An integrated pressure-reducing pilot ensures a precise and stable pre-set downstream water pressure.

The 400Y-4DC is ideal for open-nozzle systems with a high-pressure water supply.

It is available with electric components to suit any hazardous location.
