Emerson has released its ASCO Series 273 Pinch Valve for the life sciences manufacturing market.
The new series expands Emerson’s extensive pneumatic valve offering to single-use batch applications in bioreactor and fermentation tanks, tangential flow filters, chromatography skids and other drug discovery lab applications.
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.
A pneumatically actuated pinch valve, the Series 273 makes no contact with process media, features a high lifecycle and provides a reliable pinching force over repeated use.
Available in anodized aluminum and 316 stainless steel, the series is suitable for peroxide fumigation and includes a position indication option for valve on/off status feedback.
