FP 405-11
The BERMAD Model FP 405-11 is a simply designed, manually operated, on/off valve. It is particularly suited for
monitors and industrial high capacity hydrants.
The Model FP 405-11 is held closed by line-pressure applied to the control chamber of the valve. The closed
valve prevents the water (or water foam) from passing through the valve, keeping the downstream piping dry.
In the set position, the line pressure is applied to the control chamber of the valve. The pressure holds the main
valve’s diaphragm and plug against the valve seat. Seal is drip tight. The Check Valve traps high pressure peaks
ensuring that the valve remains locked in the closed position to maintain drip tight sealing.
To open, a ¼ turn of the Manual Release Pilot handle releases pressure from the control chamber through the
opened Manual Release Valve. The diaphragm plug is then pushed open by the upstrim force at its bottom, allowing
water to flow into the system.
