The Coperion WZK dual channel diverter valve can be specially designed for the mineral industry. The unit has an asymmetric design with approximately 34- to 37-degree angle, depending on size, suitable for distributing and collecting in pneumatic conveying lines and in gravity applications. The rotor has symmetrical channels that can be reversed to extend life, making it ideal for potentially high wear materials.

The WZK is engineered with pressure differential up to 5 bar(g), vacuum -0.5 bar(g) and pressure surge proof to 10 bar(g), by design. The valve is equipped with a pressure assisted seal and maintenance can be performed without removing from service. The WZK is Coperion’s original world-wide top selling diverter valve.

Material of construction is cast aluminum, but channels consist of stainless steel pipe inserts. For the mineral industry, these inserts can be made of hardened steel 100CR6 or tungsten carbide coated for longest life.
