Abstract
A fluid control valve includes a valve body having a passageway, a valve stem, a valve seat, a floating stem end member and a captive internally threaded insert. The valve stem has a molded-on, color-coded external thread mating with the internal thread of the color-coded insert so as to advance or retract the stem through the valve body as the stem is turned by an operating knob. The stem end member includes a pair of retaining arms which snap over a shoulder on the stem and these arms are confined within the valve body. These arms retain the stem end member on the stem while still permitting free rotation of the stem within the stem end member. As the stem advances into the valve body, the stem end member is moved into sealing contact with the valve seat, thereby blocking the continued passage of water from an inlet port to an outlet port. The valve seat also serves as a union nut mount, and is slotted for easy removal from the rear by use of a screwdriver for servicing.
