A pinch valve is a valve that can open/close a tube by moving a pinching head (see the red square parts in the above pictures) to control the flow of fluid. As the wetted part is only the tubing, one of the features of the pinch valve is the prevention of cross-contamination because the flow channel can be kept clean at all times by just replacing the tubing. It is, therefore, suitable for medical, clinical, or analytical instruments. A pinch valve can also be used for liquid containing solid particles (slurry). Furthermore, the pinch valve has the advantages of a low-pressure loss and less stagnant fluid.
