  • Stepper motor pinch valve, suitable to shut off media without producing neither turbulent flows, nor dead spaces. Particularly suitable for most of the analytical, medical and food applications.
  • If equipped with fitting control electronics, the valve can perform ON-OFF functions, as well as analog input and potentiometer control.
  • The system allows a bi-directional through flow and a high flow rate. The valve is suitable for elastic tubings with hardness up to 90 Shore A.
  • The tubing (not included in our supply) is the only material in contact with the fluid.
