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-3DC is ideal for open-nozzle systems with a high pressure water supply and is available with electric components to suit any hazardous location. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems.

A typical installation of the BERMAD model 400Y-3DC features actuation via a hydraulic relay valve and three-way solenoid valve, triggered by a signal from a fire & gas control system or an on-site emergency pushbutton.
When open, and fitted with a limit switch the valve can send a feedback signal to a remote valve
position monitoring system.
A pressure reducing pilot valve integrated in the control trim ensures a precise and stable pre-set downstream water pressure.
