The new intelligent positioner TopControl Basic, Type 8694 is designed for applications in hygienic process environments. With a compact design, it is optimized for integrated mounting on the company’s Element and Classic valve ranges, as well as third-party process valves. The stainless-steel housing has IP ratings up to IP 67 and is chemically resistant for use in food-and-beverage and pharmaceutical industries. Installation of the positioner is simplified through the Process Tune function and integral DIP switches, which are used to set up the close-tight function, select characteristic curves, select manual or automatic operation and use binary input to control valve activation. — Bürkert Fluid Control Systems, Cirencester, U.K.
