SPX FLOW, Inc. has launched a new control unit as a part of the CU4plus platform that now includes IO-Link communication protocol. The CU4plus IO-link Control Unit works with all APV and Waukesha Cherry-Burrell valve ranges and can be retrofitted into any existing installed base when paired with an IO-Link master. The CU4plus valve control unit fits any SPX FLOW air-operated sanitary valve bringing unprecedented safety, simplicity and reliability to dairy, beverage, brewery, processed food, healthcare and pharmaceutical processes.

The addition of the IO-Link technology, which is an Industry 4.0 data-ready communications protocol that connects sensors and actuators to process automation systems, allows data to send and retrieve to/from hygienic valves. It forms the backbone of many food and beverage control systems. It is hygienic hardware that does not need to be enclosed in a stainless-steel panel, a feature which reduces installation time and cost. What makes the CU4plus IO-Link Control Unit different is the pressure sensor that allows end-users to better monitor air pressure used to actuate the valve.

The unit can easily integrate into an existing system, meaning customers don't have to upgrade a whole line to optimize performance, increase uptime and maximizes interoperability with other protocols. Benefits of this new CU4plus IO-Link Control Unit include: Ease of Installation and Use: IO-Link allows for interoperability across multiple protocols enabling end-users to quickly integrate with other fieldbus protocols. Improved Uptime: Monitor real-time process data to update valve limit set values to optimize/trigger needed maintenance intervals (activation hours, cycles, actuation reaction times, control air pressures).

Robust Network and Less Downtime: Complete configuration setup is an automated process that is stored in the IO-Link master such that it can be reloaded in any replacement unit (including the firmware). This leads to shorter downtimes and accurate, error-free automation restoration of the original valve relevant setting of the control unit. Enhance CIP and Sustainability: For mix proof valves seat lifting can work based on pulsation with defined ON/OFF scheme to significantly improve CIP time, fluid costs, and disposal waste.

The CU4plus IO-Link Control Unit extends SPX FLOW's range of control units which are available as Direct Connect and AS-i. Like other control options, this new control unit can be used with SPX FLOW's broad line of valves which includes the recently introduced D4 mix proof valves series. These expansions are well suited to support a broad array of applications in various hygienic processes with viscous fluids that are difficult to clean in place and valves and within hazardous environments.
