The BERMAD model 400Y-3UM is an elastomeric, hydraulic, line pressure operated deluge valve, designed specifically for advanced fire protection systems, and the latest industry standards.
The 400Y-3UM is activated by a 3-way solenoid valve, which actuates a latching relay valve, to open the main valve.
Once open, the main valve will not close until locally reset. The optional valve position indicator can include a limit
switch suitable for Fire & Gas monitoring systems.
The 400Y-3UM is ideal for systems with open nozzles for water or foam discharge, available with electric components to suit any hazardous location.

A typical installation of the BERMAD model 400Y-3UM features automatic actuation via a relay valve and three-way solenoid valve, triggered by a signal from a fire & gas control system or an on-site emergency pushbutton.
When fitted with a limit switch, the valve can send a feedback signal to a remote valve position monitoring system.
