To begin with, the well-conceived design is not only optimized for easy access, but also for low maintenance costs and a long lifetime. Thanks to its small rotation angle, the inner parts are barely affected by wear. In addition, operators can turn the valve by 180° at the first sign of wear to even double the component’s operational life span. The aluminum cast with stainless steel pipe inserts make the valve as light weight as possible. Based on its pressure-assisted pipe seals and well-thought-out working principle, it is also easy to operate. At the same time, the WZK ensures highest safety levels: It is suitable for ATEX zone 1/21 and 2/22. Moreover, the compact design comes with no external parts contributing to a safe environment for operators and other production staff. All in all, the WZK has the reputation of being a cost-effective and reliable two-way diverter valve.
