Abstract
A flow shut off valve for residential water line pressure includes a self cleaning valve element held in a housing having an inlet, an outlet section and an outlet adapter with a fluid passage connecting the inlet and the outlet adapter. The inlet and the outlet adapter include exterior threads for connection to a further item. The valve element is slidably mounted within a passage in a poppet guide and metering slot insert having one or more metering slots that allow variable fluid flow between the inlet and outlet adapter. A spring biases the valve element toward the inlet. Reduced back pressure at the outlet adapter drives the valve element into a closed position with a sealing surface against the valve seat to terminate flow. The flow shutoff valves are contemplated for integration with stop valves supplying water to employment with household appliances, sinks, toilets and the like.
