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: 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 valve with a controlled closing system includes housing having an inlet port, a liquid outlet port, and an inlet chamber. A pressure responsive closing mechanism is disposed between the inlet port and the liquid outlet port. A control chamber is in fluid communication with the inlet chamber via a fluid passage. The fluid passage includes a controlled closing system for controlling opening and closing of the fluid passage. The controlled closing system includes a seal movable with respect to and sealable against an opening of the fluid passage.
