Our standard pinch valves are designed to be either fully opened or closed, but there is a growing number of applications where proportional and more accurate control of the fluid within the tube is required. For this, we have developed the Acro PE-900 Series motor controlled pinch valve. The pinch valve is controlled by a high force, high accuracy linear drive with integrated encoder.



  • Provides a robust solution for accurate closed loop proportional control and precision fluid management
  • Dependable, compact and cost-effective solution
  • Pinch head designed for washdown and clean rooms
  • Controls high media/fluid pressures up to 75 psig (5.2 barg)
  • Flexible tubing sizes from 0.063” to 1.625” O.D. (1.6 mm to 41.3 mm)
  • Support tubing durometer up to 75 Shore A

 Pinch Valve Benefits:

  • Designed for Bio-Pharma, Bio-Processing, Food and Beverage and Industrial applications where sterility and wash down procedures are needed.
  • Offer reliability and performance when working with hard or larger diameter tubing that requires stronger pinch forces.
  • Specifically designed for disposable tubing
  • Each model contains an easy snap-in tube slot for quick loading and unloading procedures
  • Optional safety caps are available on certain models to address operational hazards
  • Improve your batch yield efficiency and quality


  • Designed for closed loop control for most accurate and predictable performance
  • Software pre-loaded for easy set-up and operation
  • RoHS/CE Compliant
  • High resolution encoder feedback
  • DIN rail mountable (controller only)
  • Noise Level 50 dbA Maximum
