The principle of the pinch valve is extremely simple and adaptable. It works on the same principle as when you pinch the garden hose between your fingers to stop the flow. It is not possible to give a much simpler explanation that the above, however, there are a number of points about pinch valves in operation that must be understood to avoid potential problems. First we have to have a look back at section 2.1, where on page 2 it is state under disadvantages that the NR solenoids only have a short stroke. This is also a disadvantage with pinch valves, as it is necessary to have a stroke equivalent to at least the bore of the tube you are using for it to work from fully open to fully closed. If the required stroke is not available, it is necessary to save stroke on the open state. A diagram is given to illustrate this point.
