PRODUCT SHEET
Engineered for durability: minimal seal wear, K-seal technology, and symmetric rotor geometry.

Advanced Wear-Reduction Technology for Maximum Uptime

The WZK’s robustness is rooted in its low-rotation-angle mechanism, which reduces friction and keeps sealing wear to a minimum. Its symmetric turning component enables a 180° repositioning as soon as wear becomes visible, doubling operational service life with minimal intervention. The patented K-seal provides superior sealing reliability between the housing and rotor, while the precisely machined, symmetrical dual-conveyor-channel rotor in K-Execution ensures efficient switching and uninterrupted material handling performance.

Why the Original WZK Dual Channel Diverter Valve Remains One of the Best-Sellers to This Day

When the WZK diverter valve was first introduced around 60 years ago it was an immediate success. No wonder the design of the “Original”was copied so many times by other valve manufacturers (unmatched in execution) but yet, still remains one of Coperion‘s best-selling valves. It is proven, reliable, maintenance-friendly and suitable for various conveying systems as well as food applications.
