Pinch Wall Rubber Sleeve

Pinch valves are typically used in applications where the media needs to be completely isolated from any internal valve parts. The sleeve will contain the flow media and isolate it from the environment hence reducing contamination. A sleeve valve takes the form of one or more machined sleeves. It fits between the piston and the cylinder wall in the cylinder of an internal combustion engine, where it rotates and/or slides. The cylinder wall has inlet and exhaust ports, identical to a two-stroke motor.
