Electro-Pneumatic, Pressure-Control, Latching Deluge Valve | FP 400Y-6DC-H

Electro-Pneumatic, Pressure Control Deluge Valve with Local Reset FP 400Y-6DC-H


The BERMAD Model 400Y-6DC-H is an elastomeric, hydraulic line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.

The 400Y-6DC-H is activated by a fall in pneumatic pressure caused either by the activation of a sprinkler in the dry pilot line or by an electric signal to the 3 way solenoid valve.

The 6DC-H can also be activated remotely either pneumatically or electrically. Once open the 6DC-H latches in the open position, until locally reset.

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-H is ideal for open-nozzle systems with a high pressure water supply. It is available with electrical
components to suit any hazardous location.

System Installation


A typical installation of the BERMAD model 400Y-6DC-H features automatic actuation via a pneumatic universal relay valve, triggered by a fusible plug loop.

It can also be triggered electrically by a signal from a fire & gas control system or an on-site emergency pushbutton.

Once open, the relay pilot URV-M will latch mechanically keeping the 400Y-6DC-H open, until locally reset.

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

When fitted with a limit switch the valve can send a feedback signal to a remote valve position monitoring system.
