Pneumatic, Pressure-Control, On-Off Deluge Valve | FP 400Y-4DC

Pneumatic, Pressure Control On-Off Deluge Valve FP 400Y-4DC


The BERMAD model 400Y-4DC is an elastomeric hydraulic, line pressure operated, deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.

The 400Y-4DC is activated by a pneumatic relay valve. Opening and closing of the valve can be controlled remotely.

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

The BERMAD 400Y-4DC is suitable for open-nozzle systems with a high pressure water supply. The pneumatic control makes it ideal for use in freezing environments and corrosive media.

The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems.

System Installation

A typical installation of the BERMAD model 400Y-4DC features actuation via a pneumatic universal relay valve.

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.
