Emerson has launched its ASCO™ Series 273 Pinch Valve for the life sciences market. This new series expands on Emerson’s already-extensive pneumatic valve offering to single-use batch applications in bioreactor and fermentation tanks, tangential flow filters and chromatography skids, among other applications.
The Series 273 makes no contact with process media, features a high lifecycle and provides a reliable pinching force over repeated use. The series is available in anodized aluminum and 316 stainless steel, and is suitable for peroxide fumigation and includes a position indication option for valve on/off status feedback.
The Series 273 features a 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.
The pinch valve can be actuated using ASCO™ Series 501 or Aventics™ AV Series pneumatic valve manifolds and ASCO 580 CHARM electronics, which seamlessly integrates into DeltaV™ distributed control system.
