Abstract: A valve assembly includes a housing which has a liquid inlet and a liquid outlet, a cover affixed to the housing, a flow regulating assembly located in the housing, and an anti-cavitation flow diverter mounted in the housing. The anti-cavitation flow diverter includes an outer wall that surrounds an inner hollow portion. Sets of flow apertures are formed through the wall thickness of the outer wall. Each flow aperture is open to the inner hollow portion and extends at an angle along a non-radial path through the outer wall. Flows of liquid flowing through each set of the flow apertures impinge upon each other at meeting points which are spaced from inner surfaces of the housing.

Abstract: The present application concerns a valve, and particularly position indicating assembly for use therewith. The position indicating assembly comprises a first end engageable with a valve member of the valve, an opposite second end displaceable with respect to a body of the valve in response to displacement of the first end, and an elongate bendable portion, extending between the first end and the second end, configured, upon movement of the valve member, to transmit forces operating along the elongate bendable portion, at least from said first end to said second end, so as to displace said second end, the elongate bendable portion being further configured for damping forces operating transversely thereto by reversibly bending.

Abstract: An air valve assembly (10) includes a main housing (12) including a coupling flange (14) for coupling to a pipe, and an air valve (20) fluidly coupled to the main housing (12). An actuator (28) is in fluid communication with the air valve (20) and a discharge tube (40). A non-contact liquid level sensor (30) is located in an external housing coupled to the main housing (12). The non-contact liquid level sensor (30) is in operative communication with the actuator (28).

Abstract: An air release valve (10) includes a housing (11) fluidly connectable to a water line, a valve seat (12) secured to a portion of the housing (11) and formed with one or more air exit passageways (14), a seal (18) formed as a spring disc and including a stem (28) slidingly engaged with the valve seat (12), and a weight (20) coupled to the seal (18). In a sealed configuration the seal (18) presses against the valve seat (12) and seals the one or more air exit passageways (14) from air passing therethrough and in an open configuration the seal (18) is moved by the weight (20) so that the seal (18) is not pressed against the valve seat (12) and allows passage of air through the one or more air exit passageways (14).

Abstract: A PRV is provided, comprising an inlet, an outlet, and a pressure regulating system therebetween to maintain a set pressure at the outlet. The PRV further comprises a selection system configured to select between the two working pressures based on the pressure of the fluid at the inlet of the PRV, and to direct the pressure regulating system to maintain the set pressure at the outlet at the selected working pressure. The selection system comprises a pressure-motion transducer for directing the set pressure when in pressure communication with the inlet, and an auxiliary valve having an auxiliary inlet in pressure communication with the inlet and an auxiliary outlet in pressure communication with the pressure-motion transducer. The auxiliary valve is configured to establish pressure communication between its inlet and outlet when pressure in the inlet traverses a predetermined threshold.
