WAREX - Custom Solutions for Industrial Weighing Systems
For use in industrial weighing systems, WAREX Valve GmbH has developed two particularly lightweight butterfly valves in nominal diameters DN 400 and DN 500.
For use in industrial weighing systems, WAREX Valve GmbH has developed two particularly lightweight butterfly valves in nominal diameters DN 400 and DN 500. The custom-designed valves are bulk-material-tight and, including their pneumatic actuators, weigh only 22 and 31 kilograms, respectively.
The development began with a customer’s request to reduce the weight of the components used in their weighing system as much as possible. At the same time, the system had to maintain the necessary sealing performance and ensure reliable operation.
The aluminum valve disc plays a key role in the lightweight design. In addition, the entire valve assembly was designed for exceptionally smooth operation. The resulting low operating forces allow for the use of a comparatively small and lightweight pneumatic rotary actuator.
A Rotork RC240-size actuator is used. In the selected configuration, this compact actuator weighs just 4.9 kilograms and delivers a torque of approximately 300 Newton-meters with an air supply of 6 bar.
The complete DN 400 version, including the actuator, weighs just 22 kilograms. The larger DN 500 version has a total weight of 31 kilograms.
With this, the new DN 500 special version weighs around 50 percent less than a standard WAREX valve of the DKZ 110 type in the same nominal size. Compared with a conventional gray cast iron version weighing up to approximately 150 kilograms, the weight reduction is nearly 80 percent, according to the company.
The reduced overall weight facilitates installation and handling while simultaneously reducing the load on the surrounding plant structure. Particularly in weighing systems, mobile plant components, and applications with limited installation space, the compact design offers significant engineering advantages.
With this development, WAREX underscores its expertise in customer-specific valve solutions. In addition to standardized industrial valves, the company, based in Senden, develops custom designs that are specifically tailored to the structural and process-related requirements of each individual application.
