Electro-Pneumatic, Pressure-Control, On-Off Deluge Valve FP-400Y-6DC

  The BERMAD Model 400Y-6DC is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y 6DC is activated by a fall in pneumatic pressure of the pilot line or by an electric signal to a 3 way solenoid valve. The 400Y 6DC can also be activated remotely either pneumatically or electrically. When open an integrated pressure reducing pilot valve regulates the main valve to maintain a precise, stable, pre-set downstream pressure. The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems. The 400Y-6DC is ideal for open-nozzle systems with a high pressure water supply. It is available with electrical components to suit any hazardous location.

Typical Product Applications

Typical Applications

  • Remote control water spray systems
  • Foam applications
  • Corrosive water supplies
  • High pressure water supply
  • Dual redundant detection system


System Installation

A typical installation of the BERMAD model 400Y-6DC features actuation via a pneumatic universal relay valve.

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
position monitoring system.

A pressure reducing pilot valve integrated in the control trim ensures a precise and stable pre-set downstream water pressure.
