The Flow-Rite® Flow Control Pinch Valves:
  • work with all types and size of flexible tubing up to ½" (12.7mm) OD, Shore 70A Durometer and softer.
  • are suitable for use on thicker wall vacuum lines.
  • can easily be installed on existing tubing runs.
  • are non-wetted - can be used, re-used and disposed of without fear of contamination.
  • are fabricated from high quality Delrin® acetal homopolymer for strength and durability.
  • operate on a unique principle that enables calibrated needle valve style adjustability.
  • have a graduated scale reading that represents the gap, in millimeters, across the outside of the tubing.
With the Flow-Rite® Flow Control Pinch Valve:
  • calibration is accurate and repeatable.
  • a setting can be recorded and produced.
  • flow rates are adjustable from a fully open flow to a fully closed position.
  • fine adjustments are easy - for example, valve can be fine-tuned to a nearly closed position to dampen pulsation to a pressure
