Abstract
A bidirectional excess flow valve for automatically stopping delivery of a fluid from a supply in a fluid network. The valve has a housing defining an interior forming a fluid passageway along a flow axis between a first opening and a second opening. The valve also has a valve seat in the interior, the fluid passageway extending through the valve seat, and a first and second shutoff element disposed on opposite sides of the valve seat. The shutoff elements are set apart from the valve seat assembly in an open position to allow flow through the fluid passageway. In a closed position, the first or second shutoff element is configured to move against the valve element assembly to close the fluid passageway when flow through the fluid passageway exceeds a predetermined level.
