Alternatively, Bürkert’s Element
system is sealed and prevents ingress of moist, contaminated air. The clean, dry air used to pressurise the actuator is recycled back into the spring chamber via an integrated pilot valve, preventing corrosion of the actuator spring and removing humidity build-up inside the actuator. This also removes the possibility of bacteria collecting inside the actuator, which could potentially contaminate the hygienic atmosphere. In addition, the positioner is also sealed and the area around the electronics is pressurised to keep out any moisture, contributing to the valve system’s long life.
Robust design foR tough enviRonments With a highly durable, stainless steel body, the Element continuous control valve is also free from external corrosion. It can be used in hygienic environments and can undergo a rigorous washdown with chemical solutions without pitting or degrading, which can attract bacteria. Similarly, the valves are designed for simple and effective cleaning, with the smooth edges reducing bacteria build-up and the sleek design providing a clean, clinical look. The polished stainless steel finish also means there’s no paint that can peel off in the hygienic environment and the high IP rating makes the valve durable against washdown and moisture ingress.
As the Element continuous
control valves are more compact, they also use less compressed air. By their nature, continuous control valves can be in near constant motion so the savings to be obtained from air usage can be significant across a plant. On average usage with 50 valves per site, a typical saving of £2,500 per year can be achieved by using Bürkert’s more compact valves. The advantages of a smaller, lighter valve also include easier maintenance and as the largest Bürkert Element continuous control valve can be held in one hand, pipework does not need any reinforcement whether for new or retrofit projects.
the answeR foR continuous contRol valve applications The advantages of the Element system can also be attributed to globe control, angle seat and diaphragm valves and the positioners can communicate with analogue control signals as well as all common Ethernet-based industrial networks.
The Element system ensures
high, repeatable accuracy across its lifetime, using technology that makes it last significantly longer than the alternatives. The result is improved performance, reduced downtime and lower overall cost. For continuous control valve applications, Bürkert’s Element system is the answer.
