Abstract
A combination valve that provides both positive shut off and excessive flow shut off. A rotary valve is provided. In its first position an integral excessive flow shut off valve allows normal flow and shuts off if high flow occurs. In a second position the flow is shut off independent of the excessive flow valve. A third position is provided for purging a repaired or new system and for resetting the excessive flow shut off valve.
