The operating principle of these solenoid valves is basically different from the one of the other series.
The pinching device is moved by a solenoid operator and cuts off the fluid by pinching or releasing a tubing in soft silicon (or other soft material). The fluid can flow in either direction with a high rate of flow, without turbulences and without dead spaces.
Thus, pinch solenoid valves can control all the fluids that are compatible with the tubing material, protecting them from all contamination, including temperature changes.
These characteristics, plus the fact that the tubings are extremely easy to install and replace, make this solenoid valve suitable for a wide variety of applications, particularly the control of physiological, medical and food fluids.
Also for these series 2/2 or 3/2 normally closed or open are available plus miniaturised version and latching models. All models are silenced.
