ABSTRACT:
A fluid valve includes a sleeve having inlet and outlet ports. There is a stem movable within the sleeve between open and closed positions and having an inlet port and an outlet port. The stem inlet port is in communication with the sleeve inlet port and the stem outlet port is movable into registration or communication with the sleeve outlet port to define a path of flow through the valve. A seal is carried by the sleeve and cooperates with the movable stem to close the path of flow. There are means for reducing noise normally attendant to opening the valve which includes a passage in the sleeve directly adjacent the sleeve outlet port. The passage is in communication with the stem outlet port as the stem outlet port initially moves to open the path of flow to divert water and reduce pressure at the communicating outlet ports.
