ASCO 273 & 373 Series Pneumatic Pinch Valve

The ASCO Series 273 is a 2-way normally-closed or normally-open pressure-operated pinch valve designed to assure integrity of high-purity liquids in biotechnology, pharmaceuticals, diagnostics, single-use technology (SUT), and food and beverage markets.

Typical applications include single-use bioreactors, Tangential Flow Filtration (TFF), and Chromatography skids.

The ASCO Series 373 is a 3-way normally-closed or normally-open pneumatic pinch valve also designed for single-use systems, including chromatography applications.

Pneumatic pinch valves control the flow of the media by using pressurized air to operate the pinching mechanism and open or close the valve.

The hermetic separation of valve control mechanism and the process media within the flexible, single-use tubing prevents contamination.

A large range of body sizes are available to accommodate a wide variety of tubing sizes.
