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.

A mixing valve characterized by: a valve housing having a first and second supply port and a mixed fluid discharge port; a valve means for controlling the proportion of flow from each respective supply port to said mixed fluid discharge port by having a first position wherein said first supply port is open and said second supply port is closed and movable to a second position wherein said second supply port is open and said first supply port is at least partially closed; an operating stem connected to said valve means for adjusting the proportion of flow from each respective supply port; a handle operably connected to said stem; limit means for limiting the movement of said handle with respect to said valve housing; said valve means constructed so that when fluids supplied to the respective first and second ports are interchanged said valve means can be moved such that it undergoes a reverse function wherein an initial position opens said second port and closes said first port and a final position opens said first port and at least partially closes said second supply port; an orienting insert means interposed between said operating stem and said handle to orient the handle with respect to said housing such that said handle has a first position and is movable to a second position when said valve means is in one of its first position and initial position and is movable to one of its second position and final position respectively; and a positive engaging means affixed to said orienting insert means and allowing said insert to be positioned with respect to said handle in only a first position and being removable to allow said handle to be deliberately oriented with respect to said stem and insert in an alternate position.
