Abstract: A fluid metering device for monitoring flow of fluid is provided. The fluid metering device comprises: an electric motor; and a housing having a manifold section, a motor adapter plate and a pressure retaining container, said pressure retaining container encompassing a pressurized chamber having a hydraulic pump placed in the pressurized chamber; and the manifold section including an air bleed valve and a pressure biased relief valve for maintaining pressure within the housing.

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.

Abstract: The valve comprises a housing defining a flow passage, an outer cylindrical wall, an inner cylindrical wall, and a valve seat. An annular cavity is formed between the outer cylindrical wall and the inner cylindrical wall. A valve member is slidably mounted within the housing. The valve member includes an annular skirt section extending in the downstream direction. A downstream-facing portion of the valve member comprises a sealing portion configured to selectively engage the valve seat. The valve member is movable between an upstream no flow position, a downstream shutoff position, and a normal flow position intermediate the no flow position and the shutoff position. A biasing element is disposed between the housing and the valve member so as to bias the valve member away from the valve seat.

Abstract: A flow shut off valve for residential water line pressure includes a housing having an inlet, an outlet and a passage there between with a valve seat in the passage. A valve element is slidably mounted within the passage and includes a cavity open to the inlet and orifices partially restricting flow from the cavity to the passage. A spring biases the valve element toward the inlet. Reduced back pressure at the outlet drives the valve element into a closed position with a sealing surface against the valve seat to terminate flow. The restrictive orifices in the valve element extend from the cavity to the periphery of the valve element and, in a position toward the inlet, the restrictive orifices are closed by the housing to block communication between the inlet and the outlet. In an intermediate position, the orifices are open and the sealing surface is not against the valve seat. A motion damper may be employed to allow for start-up conditions on sprinkler systems and the like.

Abstract: The present flow shutoff valve comprises a flow metering sleeve positioned within a flow passage. The sleeve and a housing of the valve define an annular space. The sleeve includes a flow metering aperture downstream of the annular space. A valve member is slidably mounted within the sleeve. The valve member is movable between a no flow position, a normal flow position and a shutoff position. The valve is self cleaning, so that it reduces the buildup of sediment within the valve.
