Pneumatic Pinch Valve Optimizes Single-use Batch Production

Parker Sized

Emerson (St. Louis, MO) has released its ASCO Series 273 Pinch Valve for the life sciences market. The new series expands Emerson’s extensive pneumatic valve offering to single-use batch applications in bioreactor and fermentation tanks, tangential flow filters (TFF), chromatography skids and other drug discovery lab applications.

The Series 273 features an innovative pinching mechanism that remains firmly in place to provide better tube retention and eliminates breakage or damage to the soft tubing. It also includes a safety guard to prevent exposure to moving parts, as well as a manual override feature that lets operators insert or remove tubing without actuating the valve during unplanned batch switching.
