The GEMÜ Q40 2/2-way pinch valve has a stainless steel piston actuator and is pneumatically operated. The valve guides a tube which is compressed from above by a compressor to control and regulate media. The compressor's specially developed contour and the inserts' contour minimise the strain on the tube and thus increase the tubes' service life. Tubes can be safely inserted and removed in simple steps and without tools. The available control functions are "normally closed (NC)" and "normally open (NO)". An integral optical position indicator is standardResistant stainless steel piston actuator, free from non-ferrous metals Fast, safe tube replacement Simple replacement of inserts and compressors for various tube sizes with the same actuator High quality and long service life Minimized strain on the tube due to the optimized compressor Positioners and process controllers can be mounted Several installation options possible in the plant thanks to the mounting flange or female thread on the body Operating pressure:Please observe the tube manufacturer's specifications Tube's outside diameter:1/4'' | 3/8'' | 7/16'' | 1/2'' | 5/8'' | 3/4'' | 7/8'' | 1 1/8'' | 1 1/6'' | 1 1/4'' | 1 2/5'' | 1 13/32'' | 1 3/7'' | 1 1/2'' Body materials:1.4404/PA6 | PA6
