  • NO LEAKAGE: : PINCH VALVES HAVE NO BEARINGS, SEALS, OR PACKING, SO THEY DON'T LEAK.
  • STRAIGHT FLOW PATH: : PINCH VALVES HAVE A STRAIGHT FLOW PATH THAT MINIMIZES TURBULENCE AND FRICTION
  • GOOD FOR THROTTLING: : PINCH VALVES CAN BE USED FOR THROTTLING APPLICATIONS WITH AN EFFECTIVE RANGE OF 10% TO 95% OF THEIR RATED FLOW CAPACITY.

DISADVANTAGES

  • PRECISE NEEDLE
  • LIMITED TEMPERATURE RANGE: : PINCH VALVES HAVE A LIMITED TEMPERATURE RANGE AND CAN'T OPERATE IN SERVICES THAT REQUIRE HIGH TEMPERATURES.
