Engineered for precise fluid metering, bio-pharmaceutical processing, and laboratory fluid control, our manual sanitary pinch valves provide zero-contamination flow shut-off. By directly pinching flexible medical-grade silicone, PTFE, or Pharmed tubing from the outside, the process fluid never comes into contact with the valve mechanism, completely eliminating cross-contamination and dead legs.
Constructed with corrosion-resistant 316L stainless steel / anodized aluminum housing, these compact pinch valves feature fine-pitch manual adjustment knobs for accurate, repeatable flow restriction without damaging flexible tubing walls.
EU Customs Tariff Advantage: Bestec benefits from an approved individual lower anti-dumping duty rate in the EU, offering European medical device manufacturers and laboratory equipment integrators significant tariff savings.

Fluid Contact Status
100% Zero Contact (Fluid touches inner tube wall only)
Cleaning Standard
Outer body autoclavable & wipe-down resistant
Mounting Options
Panel Mount / In-Line Tubing Clamp Frame
Key Engineering Features
Zero-Contamination Fluid Isolation: Process media passes strictly inside the flexible sleeve, keeping the internal mechanism clean and preventing cross-batch contamination.
Preserves Tubing Integrity: Smooth-contoured clamping jaws apply uniform pressure, preventing tearing, permanent deformation, or mechanical stress on silicone/PTFE tubes.
Micro-Metering Precision Knob: Multi-turn graduated adjustment cap enables precise micro-flow regulation and rapid drip-free shut-off.
Compact Panel-Mountable Design: Compact footprint allows easy integration into benchtop laboratory systems, automated dosing skids, and filling lines.
Primary Precision Applications
Biopharmaceuticals & Fermentation: Sterile fluid sampling, media dosing, and bioreactor harvest lines.
Medical & Laboratory Equipment: Analytical instruments, automated liquid handling, and diagnostic reagents.
