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.
