Fine adjustments to fluid flow are easy to achieve and they are repeatable with the Flow Control Pinch Valve. Non-destructive, leak proof valves easily mount on existing tube lines, so fluid contact with the valve is eliminated. No fittings, cutting or removal of existing tubing is needed for installation. Easy-to-read metered scale on valve body lets you calibrate with needle valve style adjustability, from 0 to full flow. Made of high quality Delrin acetal homopolymer for strength and durability.
Compact, three-piece construction allows space-efficient system layout. Lightweight (1.75 lb [0.79 kg]), high-strength PEEK body provides low thermal conductivity and resists corrosion. Valve offers secondary packing/body seal with telltale leakage detection port.Manual and pneumatic actuation available.

A manufacturer of medical equipment needed an automated way to control the flow of fluids in dialysis equipment. Using the Original Line technology, Bimba developed a cylinder that precisely controlled the flow of fluids by pinching a tube when extended.
Every pinch valve is factory tested with nitrogen at its maximum pressure rating to a maximum leak rate of 0.04 std cm3/min at the seat and shell. Body seals are tested with helium at 10 psig (0.68 bar) to a maximum leak rate of 1 × 10–5 std cm3/s.Optional EPDM and Aflas pinch tube elements,High-pressure valve,Steam ports,L-flange and T-flange end configurations minimize the dead leg between the pinch shutoff and steam purge ports to facilitate inline steam cleaning
Valve body seal kits with Aflas, EPDM, and red silicone pinch elements are available.Pneumatic actuators
