Bürkert – Long-term accuracy for process valves in food & drink applications
Bürkert – Accuracy, reliability and a long service life – all the attributes desired in many components of a manufacturing process, especially control valves. Bürkert’s Element control valve system delivers next-level accuracy of 99.9% and a service life more than three times that of conventional designs. The innovative features of the Element series ensure process accuracy, optimize ingredient usage and minimize costs.
Food and drink production relies on accurate manufacturing processes to ensure uniform, high-quality products. However, the immediate environment poses many challenges to the equipment, especially with the need to maintain hygienic surroundings.
Bürkert has combined all these features into a market-leading package, more details can be found here.
Traditional designs of process valves have valve position sensors that use potentiometers with contacts and linkages that can wear over time, reducing accuracy by 0.5% in just 18 months. In contrast, Bürkert’s contactless induction sensor ensures 0.1% accuracy of the command position, even after 10 years in operation.
The key to the extended reliability and service life is the design of the Element’s air system. Conventional valves draw in ambient air, which contains moisture and chemicals from wash-down procedures that can quickly corrode the internal spring.
Bürkert’s solution uses sealed valves that prevent any contaminated air from entering. Dry process air is recycled within the valve, preventing any corrosion of the actuator spring. In addition, the positioner is also sealed and pressurised to prevent the ingress of any moisture, supporting the extended service life.

Accurate and durable process control systems enable food and drink manufacturers to maintain high-quality production without wastage or unplanned maintenance. Bürkert’s Element range of valve controllers offers a hygienic design, high IP rating and excellent efficiency in air consumption – ideal for this industry.
