Abstract: There are provided a fluid flow control valve and an orifice for a fluid flow control valve. The orifice defines two seats against which a diaphragm of the valve can be urged. Each seat defines a particular contour, including one or more channels, slots, and or protrusions that form flow control passages through which fluid flows between the diaphragm and the orifice. The orifice can be configured in either of two orientations so that either seat can be disposed toward the diaphragm. As the pressure differential across the valve increases, the diaphragm is urged more firmly against the seat facing the diaphragm and the diaphragm partially closes the flow control passages, thereby regulating the flow to a substantially uniform volumetric rate. The contours of the two seats can be the same, or each seat can be different to provide a unique controlled flow rate.

Abstract: A check valve is described which employs a magnetic biasing component, disposed external to the valve body, to exert force on a poppet, at least a portion of which is ferrous. In a "normal" mode of operation, the poppet is urged against the inlet end surface of the cavity by the basing component, and moves away from the inlet end surface of the cavity to permit fluid flow from an inlet port to an outlet (downstream) port once a differential cracking pressure is achieved. In a "bidirectional" or "purge" mode of operation, the biasing component is positioned adjacent the outlet end of the valve body to retain the poppet in an open position, away from the inlet end surface of the cavity. The bi-directional capability of the disclosed check valve is beneficial for welded installation and cyclic purging of systems, and allows for a full vacuum to be achieved because the effect of cracking pressure is eliminated.

Abstract: In a tub and shower unit, a faucet body 30 facilitates the supply of hot water and cold water either to a tub or a shower head, depending on whether a diverter valve of the unit is set in a tub mode or a shower mode. A reversible ejector tee 82 or 138 is designed for assembly with a center body 84 of the faucet body 30 to insure that hot water and cold water, which is being supplied to the faucet body, will be directed to a spout of the tub when in a tub mode without any water leaking through the shower head.
