Getting the most from steam control valves
In addition, since no impurities or moisture are drawn into the actuator, there can be no corrosion of the springs inside the actuator. The same feature also prevents the risk of biological growth, which could result in contamination of the process environment as a whole.
Attention to detail is crucial when designing innovative products, and Bürkert has some best-in-class design features which deliver market-leading process availability. This includes a defence against the ingress of airborne contaminants which is provided by diverting a small amount of clean control air into the control head, maintaining a slight positive pressure, thus achieving a simple, innovative and class-leading solution.
Bürkert Fluid Control Systems has been at the forefront of developing the technology required to make these significant steps in process control design. The Element range of intelligent control valves has been specifically designed for hygienic applications with many features that will benefit the food processing industry.
Designed as a complete unit
Air operation can also be replaced with electromotive actuation. In clean room applications where full wash-down protection may not be required the new electromotive process valve heads from Bürkert offer precision control without the need for compressed air. The new valves are designed as a complete unit and provide a robust, highly efficient solution suitable for hygienic applications where reliability and precision are key factors.
The actuator can be specified with an HMI display module that offers a rugged screen and buttons for configuring the valve settings. For a more basic application, the HMI can be omitted and the fundamental functions of the valve can be operated via a series of four DIP switches and two buttons located under a cover on the top of the valve. The new range is also compatible with the Element valve housings allowing both new and existing pneumatic systems to be converted to electromotive.
These products are all supported by a number of experienced designers and engineers, on hand to provide expert advice in designing and installing a new system. Bürkert has solutions for all options, with no bias towards one or the other, just a commitment to delivering the best value and long term reliability.
