Smart Hygienic Valve Control Intelligent Communications for Decentralized Flow Control
Bürkert’s Type 8681 universal valve control head enables data exchange for IOT applications in hygienic processing.
With its new ‘IO-Link’ communications interface, the Type 8681 universal valve control head from Bürkert Fluid Control Systems ensures cost-effective data transfer for fluid handling applications in the Internet of Things (IOT). Both operating and diagnostic data are now always available at control level, enabling simple startup, online parameterization and preventive maintenance, states the company.
Intelligent control heads aid decentralized control by providing complete management of pneumatic valves, including feedback and diagnostic functions. Applications include both process and auxiliary media, such as cleaning-in-place (CIP) solutions, in pharmaceuticals, the food and beverage industries, and biotechnology.
The firm’s proven Type 8681 control head already incorporates a universal adapter that allows it to fit most hygienic process valves on the market, adds the company. To meet the requirements of the future, the firm has now upgraded the universal valve control head with an interface that allows it to connect via IO-Link to industrial ethernet and fieldbus systems.
Standardized connectors allow the valve head to be connected easily to the plant’s control system. If a valve needs to be replaced, re-parameterization is quick and easy, since the device configuration is stored centrally and can be retrieved automatically.
In use, the IO-Link communications interface helps to make processes even more reliable, mentions the company. Information exchanged between the valve and the control system includes process data such as setpoints, valve status messages, and diagnostics such as the number of switching cycles. This enables preventive maintenance and increases system availability, concludes the firm.
