Emerson’s New Pinch Valve

New pinch valve from Emerson now allows automated control of low volume, clean and sterile liquids

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

Compact and lightweight in design, the Baumann 85000 features three major components: a tube shell body that accommodates 19mm (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.

The 85000 pinch valve with the FIELDVUE controller provides 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. When incorporated within the PlantWeb™ digital plant architecture or other process control systems, the FIELDVUE controllerequipped 85000 facilitates and enhances per-batch and overall process record keeping.

The tube shell design of the 85000 allows easy replacement 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. The epoxycoated actuator with its stainless steel fasteners offers maximum corrosion resistance.
