Pneumatically Controlled On-Off Deluge Valve
The BERMAD model 400E-4D is an elastomeric, hydraulic line operated deluge valve, designed specifically for advanced fire protection systems and the latest industry standards.
The 400E-4D is controlled by a pneumatic relay valve, typically activated by a decrease in the pressure of a pneumatic pilot line. The 400E-4D can also be operated remotely.
The optional valve position indicator can include a limit switch suitable for Fire & Gas monitoring systems.
The Bermad 400E 4D is ideal for use in systems with open nozzles for water or foam discharge also well suited for use with corrosive media or where freezing temperatures might be experienced.
