Pneumatic Pressure-Control Latching Deluge Valve | FP 400Y-4DC-H

Pneumatic Pressure Control Deluge Valve with Local Reset FP 400Y-4DC-H

 

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

The 400Y-4DC-H is activated by a pneumatic relay valve which latches the main valve open until locally reset.

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

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

The 400Y-4DC-H is ideal for open-nozzle systems with a high pressure water supply and/or relatively low flow.

The pneumatic control makes the 400Y-4DC-H suitable for freezing environments and corrosive water supplies.

System Installation

A typical installation of the BERMAD model 400Y-4DC-H features automatic actuation via a pneumatic universal relay valve, triggered by a fusible plug loop.

Once open, the relay pilot URV-M will latch mechanically keeping the 400Y 4DC-H open, until locally reset.

A pressure reducing pilot valve within the trim controls the main valve to ensure a 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.
