The BERMAD model 400Y-6U is an elastomeric, hydraulic, line pressure operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards. The 400Y-6U is activated by a 3-way solenoid valve which in turn activates a 3 way pneumatic relay valve to open the deluge valve. It is available with a latching option that maintains the deluge valve open until de-latched remotely The 400Y-6U is suitable for systems with open nozzles for water or foam discharge and is offered with electric components to suit any hazardous location. The valve’s position monitoring device features a visual position indicator that can interface with any fire & gas control system.
