Hydraulically Controlled Anti-Columning Deluge Valve | FP 400Y-5M

Electro-Pneumatically Controlled Deluge Valve with Local Reset FP 400Y-6M


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

The 400Y-6M is activated by a 3-way solenoid valve which in turn activates a pneumatic relay valve that latches the main valve open until locally reset.

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

The 400Y-6M is ideal in systems with open nozzles for water or foam discharge, and is available with electric components to suit any hazardous location.

System Installation

A typical installation of the BERMAD model 400Y-6M features automatic actuation via a 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. When open and fitted with a limit switch the valve can send a feedback signal to a remote valve status monitoring system.
