A self-aligning valve assembly and a valve plug therefor includes an elastomeric valve plug having an annular outer sealing portion with an annular sealing surface for sealing a drain hole valve seating of a receptacle. A central mounting portion is secured to a pair of telescoped tubes. A flexible diaphragm with a circular convoluted fold integrally connects the mounting portion and the outer sealing portion, and is capable of yielding to permit radial and/or tilting displacement of the outer sealing portion relative to the central mounting portion of the plug to accommodate limited misalignment between the valve tubes and the drain hole.

Self-aligning valve assembly

A fluid operated pinch valve comprises a flexible sleeve fixed at its ends within a valve casing that has a laterally facing opening through which the sleeve may be inserted and replaced without removing the valve casing from the flow line. A casing cover section has a planar sealing face that bridges the opening for sealing engagement with the main casing section, and which also seals against linear sealing flanges on ends of the flexible sleeve.
