Smart valve positioner features IO-Link connectivityBürkert says it has advanced the intelligent control of process valves with the introduction of the Type 8694 valve positioner, which is reported to be the first on the market with an IO-Link digital communication interface. To meet the latest Industry 4.0 requirements, the Type 8694 has been designed to allow for easy integration into intelligent machines operating in hygienic environments.

While still offering the accurate control of process valves expected of a positioner, the Type 8694 differentiates itself with is its interconnectivity options. IO-Link is an open communication standard that can interface with all common fieldbus and automation systems with minimal implementation work. This enables the Type 8694 to store operating parameters digitally and easily share diagnostics with a PLC. The result is a smart positioner that can be quickly implemented to provide reliability benefits.

The primary advantage of the Type 8694's intelligence is its ability to generate detailed valve data. This can be utilised to schedule plant maintenance proactively and inform asset management. With access to these metrics, operators can predict potential issues and react quickly – thereby securing continued process uptime.

Naturally, the Type 8694 offers seamless integration with Bürkert valves, especially the high-quality Element series. Designed to combine controllers, valves and sensors within a stainless steel package, suitable valves include the Type 2300 angle seat valve, the Type 2301 globe valve and the Type 2103 diaphragm valve. For further simplification, Bürkert offers free communicator software to minimise set up time. All Bürkert intelligent devices can also communicate seamlessly on Bürkert System Bus (bÜS).

A number of engrained features ensure increased flexibility in application. Internal data storage that defines operating parameters ensures that no additional auxiliary equipment is needed. By transmitting process data digitally, the Type 8694 removes the need for terminals, reduces cabling requirements and saves on PLC I/O boards for analogue inputs and outputs. Error diagnosis of cable breaks or short circuits can also be detected, which reduces the emphasis on installing short circuit fuses.

Installation of the device is straightforward. The Type 8694 can be easily connected via simple wiring and M12 connectors, with its fast setup further expediting installation and maintenance. In addition, the positioner has been designed with retrofitting in mind, so the Type 8694 can be integrated into existing processes and machines via the simple connections, enabling quick interchange and replacement.

Suitable applications include processes in the dairy, brewery, pharmaceutical and biotechnology sectors – where the Type 8694 can easily be integrated within the control loop of intelligent machines. Ultimately, the Type 8694 can suit almost all types of process control valves in a broad spectrum of applications. In all cases, the device can help increase process reliability and widen data communication.
