The BERMAD Model 400Y-6D is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-6D is suitable for systems that include electric or redundant (electric or pneumatic) fire detection systems. It opens in response to an electric signal and/ or a drop in pressure of a pneumatic pilot line. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems. The 400Y-6D is ideal for open-nozzle systems and is available with electrical components to suit any hazardous location.

A typical installation of the BERMAD model 400Y-6D features actuation via a pneumatic universal relay valve.
The valve can also be triggered electrically 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 status monitoring system.
