ABSTRACT:
A mixing valve (10) has a modular cartridge (60) rotatably mounted in housing (12). The cartridge has a bottom volume control valve plate (58) attached to a lower section (62) housing a pressure balance valve (80). The lower section (62) is secured to an upper section (120) that rotatably receives a temperature control plate (150). The plates (58) and (150) are both rotatable about a common axis (64). The plate (58) is controlled by operation of stem (180) attached to handle (34). The plate (150) is controlled by stem (160) which is operated by knob (38). An insert (250) allows the knob (38) to operate even when hot and cold water supplies are inverted. A splined hot water stop ring (228) sits in handle (34) and adaptably limits rotation of knob (38) for a selected maximum water temperature. Outer seals (58) assure that all water flows through cartridge (60) when the volume is set for partial flow.
