CONTROL VALVES WITH IO-LINK INCREASE PLANT AVAILABILITY
gases. Expertise in sealing materials and precision gas measurement ensure all components are selected to match each application. The ideal solution is centred around a manifold that connects the tank directly to the process controller and control valves as well as the pressure sensor. Pneumatic controls and the proximity of all the process control devices means the response time is at least halved compared to conventional systems. This equates to a more precise control of vessel pressure and therefore more accurate dosing.
REDUCING COSTS
A compact solution, connected directly to the vessel and designed to withstand all CIP/SIP chemicals, offers a more robust installation with a greatly reduced maintenance workload. Conventional tank pressure controllers contain valves with pistons that require regular lubrication. These systems need to be replaced up to six times per year, which equates to increased maintenance costs on top of any lost production. Modern production processes need continuous operations with cost-effective running costs. Compared to a conventional process setup that could require an annual maintenance budget of up to €42,000 (without the cost of downtime and lost production) Bürkert’s solution has been proven to operate without any maintenance costs for over eight years. There is an opportunity for process engineers to assess their current and future requirements involving gas pressure control systems. Establishing maintenance costs alone may be sufficient to seek an alternative solution, but combined with the increased precision and reliability, there is a compelling argument to investigate alternative designs.

HODIUS Mineralquellen from Burgbrohl is well known for pure, premium quality mineral water as well as soft and energy drinks from many internationally familiar licensed brands. With seven production plants and more than 600 million containers filled per year, the company is one of the leading contract bottlers in Germany.
In order to produce branded products of the highest standard, Rhodius employs the latest technology from KHS – a state-of- the-art tunnel pasteuriser. Due to its flexible speed adaptation and patented zone cut- off, among other things, the pasteuriser is capable of adapting itself to the line behaviour so that gaps and standstills are largely avoided. With high-precision sliding gate valves from Schubert & Salzer Control Systems, the zone temperature is controlled according to the speed of transport, thus ensuring that important process parameters such as pasteurisation units and maximum temperature remain virtually constant. The avoidance of stops and gaps lowers the consumption of media and energy and significantly increases the sustainability of the process.
DIGITISATION OF THE PLANT WITH IO-LINK
In order to increase the plant availability even further and at the same time to simplify maintenance, the sliding gate valves in use have now been upgraded to the latest generation of digital positioners: type 8049 with IO-link.
“Most important for Rhodius was the possibility to be able to plan maintenance measures,” explains Waldemar
Oplatschkin, who is responsible for electrical engineering at RHODIUS. “Thanks to the IO-link technology, the diagnostic data of the valve and positioner can now be monitored constantly. As a result, even the tiniest irregularities are noticed at an early stage. This gives us the time to react promptly and take the appropriate action. Physical access to the valve for the evaluation of diagnostic data such as maintenance data, pulse counter, directional classes and changes of direction is not necessary at all. With IO-link, a single cable with an M12 plug bundles the positioning signal, position feedback, data transmission and even the power supply.” Rhodius also benefits from the use of the
IO-link technology with regard to the maintenance measures themselves. Incorrect connection is technically impossible due to the coded connecting plug. Even if a replacement should be necessary, a specialist is not required. If a device has to be replaced, the digital positioner of the new valve automatically adopts the previously used parameterisation and is immediately ready to operate after self-calibration. “Through the continuous conversion of the devices in our plant to IO-link, we can increase their availability and save on important human resources in maintenance,” explains Waldemar Oplatschkin. “With the intelligent digital positioners with IO-link technology, Schubert & Salzer provided us with the possibility to integrate smart actuators into our plant in order to enable a further increase in efficiency.”
