Diaphragm valve FP-400E-4D

pneumatically-operatedregulatingfor water

Overview
The BERMAD FP-400E-4D is an elastomeric, hydraulic line-operated deluge valve designed for advanced fire protection systems and to meet current industry standards. It is controlled by a pneumatic relay valve typically activated by a pressure drop in a pneumatic pilot line and can also be operated remotely. An optional valve position indicator can include a limit switch suitable for integration with Fire & Gas monitoring systems. The FP-400E-4D is intended for systems with open nozzles for water or foam discharge and is suitable for corrosive media and freezing environments.
