ASCO Series 273 Pinch Valve
Description
The ASCO Series 273 Pinch Valve 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.
A pneumatically actuated pinch valve, 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.
The Series 273 targets single-use batch applications in the pharmaceutical and biopharmaceutical markets, but is also suitable for food and beverage production. The pinch valve can be actuated using ASCO Series 501 or Aventics AV Series pneumatic valve manifolds and ASCO 580 CHARM electronics, which seamlessly integrate into DeltaV distributed control system.
