Pinch valve allows automated control of low-volume, clean, sterile liquids

Emerson Process Management's Baumann 85000 eliminates the inefficiencies and poor control given by manually-operated pinch valves typically used in these high value applications.

Courtesy: Emerson Process ManagementEmerson Process Management has introduced its Baumann 85000 sanitary pinch valve for low flow rate, low pressure control of sterile liquids within biotechnical and pharmaceutical industries. Providing fully automatic operation, the unit eliminates the inefficiencies and poor control given by manually-operated pinch valves typically used in these high value applications.

A complete unit uses three major components: a tube shell body that accommodates ¾” pharmaceutical grade tubing; a linear spring-and-diaphragm actuator that responds accurately to controller input; and a Fisher Fieldvue digital valve controller that yields a high level of operating performance as it maintains valve reliability. Working together, the valve and controller provide an installed equal percentage flow characteristic for control accuracy. The digital controller also enables valve diagnostics that monitor the operating health of the valve assembly, providing immediate feedback to a plant host system should maintenance be required.

The tube shell allows easy changeout of the process tubing. The valve plunger does not contact the process fluid and gives a shutoff rating equal to ASME/FCI 70-2, Class VI.
