Pinch Valves

The series 273 are 2-Way normally closed and normally open pressure-operated pinch valves designed for use with high-purity liquids in biotech applications. The pneumatic pinch valve is also available as a 3-way normally closed and normally open valve, designed for chromatography applications. Hermetic separation of control mechanism and the fluid within the tubing prevents contamination, assuring maximum purity of liquids. Available in a large range of body sizes to accommodate a wide variety of tubing sizes. Typical applications include single-use bioreactors, Tangential Flow Filtration (TFF), and Chromatography skids.
