Abstract
There is disclosed a pressure-compensated mixing valve of the diaphragm and reciprocating piston type, wherein a flexible connection between the diaphragm and the pistons is provided. This flexible connection affords a self-alignment of the pistons in water inlet passages. In a preferred manner, this is used with a mixing valve providing alignment of a ported ring member that also provides in part an internal stop feature.

A valve comprising:
- a valve body having an axial bore and an open lower end extending from the bore, the valve body having an engagement means extending radially inward into the bore;

- and
- a nonrotatable ported member in the axial bore having at least two axially extending holes therethrough;
- whereby the engagement means assists in aligning the ported member in the open lower end of the valve body, and also provides a stop surface for contact with the projection member of the rotatable valve element.
