The 16.001.216 pinch valve series is normally open in operation and equipped with a 6 W solenoid coil. Therefore, it exhibits a clamping force of 1,4 N and is applicable for flexible tubes with an outer diameter from 2,2 mm and a shore hardness of 50-60°. With these tubing specifications, pressures up to 1 bar can be switched.
The flow of the medium is controlled by pinching the inserted tube. This design avoids using the traditional valve seat and membrane which can cause turbulence in the fluid flow and create dead areas in the valve housing where medium or dirt can collect. The valve is particularly suitable for applications where a high level of hygiene is required.
The resistance against chemicals depends on the selected material of the tube.
