In the industry, Wey valves stand for Swiss quality and precision, both with regard to the product and the support we offer. This reputation of the Wey products is based on exceptional functionality and process safety, ease of maintenance and long service life. Our Wey products perform in a broad range of industries & applications. Whether mining, water treatment, food & beverage, chemical or petrochemical industry, biomass, cement or waste handling – whenever fluids, powder or slurries need to be controlled, companies rely on Wey valves. Wey products comply with the highest standards of technology. With countless years of experience developing innovative designs we have become recognized for unique solutions to complex valve problems. For this reason we provide our customers from start to finish with satisfaction and a sense of security. This has always been the case. And this will also always be our rule for the future.
In order to protect personnel and process plants, an explosion must be isolated at an early stage. The Wey high speed valve HSI was specially developed for use in pipelines at risk of dust explosions. It can be installed between pipelines connecting silos, mills, dryers, filters and more where combustible dusts or gazes are processed or stored. In case of an explosion the valve closes in up to 23 milliseconds and prevents the further spreading of the explosion. The "SpeedWey" HSI is based on a through gate valve design and therefore offers a fully open and unrestricted bore passage.
