400E-Y Deluge Valve
3.3 Pneumatically Controlled System
BERMAD Pneumatically Controlled Deluge Valve is suitable for systems that include dry pilot lines with closed
pneumatic fusible plugs and piping systems with a wide variety of open nozzles. In SET position, the water pressure
supplied to the deluge valve control chamber is trapped by a closed Pneumatic Pilot Valve and holds the main
valve’s diaphragm and plug against the valve seat, sealing it drip-tight and keeping the system piping dry.
In FIRE conditions, a pilot line pneumatic pressure drop, opens the pilot valve, pressure is then released from the
control chamber, causing the Deluge Valve to open, and thereby allowing water to enter the system piping.
