Pneumatic Pinch Valve Optimizes Single-use Batch Production
Emerson’s new ASCO™ Series 273 Pneumatic Pinch Valve features an innovative design for improved tube retention and longer lifecycle—ideal for life sciences, food and beverage markets.
ST.
LOUIS (November 8, 2019) – Emerson, a global leader in fluid control
and pneumatics technology, 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. “Not only does this enhanced valve design keep operators
safer, but it also accelerates setup, lowers costs and makes unscheduled
maintenance very easy,” says John Perry, vice president, global business
development for Emerson’s ASCO valves.
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.
