ABSTRACT:
A mixing valve has a valve housing formed with a seat, a flow-controlling valve cartridge fitted to the seat, and a cover engageable over the cartridge, pivotal on the cartridge about a first axis, and formed with an aperture. A handle engaging through the aperture with the cartridge is pivotal through an arc of less than 360.degree. about the first axis with the cover for controlling a characteristic of flow through the valve cartridge and is pivotal about a second axis generally perpendicular to the first axis for controlling another characteristic of flow through the valve cartridge. Interengaging formations on the cover and on the housing allow relative axial movement of the cover and the housing in an angular position of the cover relative to the housing outside the arc and prevent relative axial movement of the cover and the housing inside the arc.
