The Series KSR pinch valve is a compliment to the flanged Series KEFR, but features slip-on end connections for fast installation and removal. Ideal for food, chemical, pharmaceutical or temporary installations, the KSR has the same benefits as the KEFR; full-port opening, a bi-directional seal, one wetted part and no packing to maintain.

The heart of the KSR is the elastomer pinch sleeve, the only wetted part of the valve. The ends slip over the O.D. of mating pipe, and are secured by heavy-duty two-piece clamps. Positive opening tabs connect the sleeve to the pinch mechanism, ensuring a complete opening. The face-to-face length of the KSR can be customized to suit a particular installation.
