The BERMAD model 400Y-5DC is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.
The 400Y-5DC is activated by a hydraulically operated relay valve, through which opening and closing of the valve can be controlled either with a remote hydraulic command or with a wet pilot line with closed fusible plugs.
An integral pressure reducing pilot valve ensures a precise, stable, pre-set downstream water pressure.
The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems.
The 400Y-5DC is ideal for systems that combine a remote wet pilot line with a high pressure water supply.

A typical installation of the BERMAD model 400Y-5DC features actuation via a pressure operated relay valve.
When fitted with a limit switch the valve can send a feedback signal to a remote valve position monitoring system.
A pressure reducing pilot valve within the control trim ensures a precise and stable pre-set downstream water pressure.
