The BERMAD model 400Y-6U is an elastomeric, hydraulic, line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.
The 400Y-6U is activated by a 3-way solenoid valve which in turn activates a 3 way pneumatic relay valve to open the deluge valve.
It is available with a latching option that maintains the deluge valve open until de-latched remotely.
The 400Y-6U is ideal for systems with open nozzles for water or foam discharge and is offered 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-6U features automatic actuation via a universal relay valve, triggered by a pneumatic fusible plug loop.
It 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.
