Unique Geometry

The ZXD Rotary Valve stands out for its exceptional performance, driven by the innovative forced emptying of the chamber and the unique geometry of its blow-through channel, which ensures a low pressure drop. This design not only enhances efficiency but also ensures optimal material flow. The valve is equipped with a premium sealing system featuring double shaft seals and a labyrinth ring for effective gas purging, which significantly reduces the risk of leakage. Additionally, the outboard bearings and a dedicated dropout opening, separate from the product area, facilitate easy detection of gasket failures, ensuring reliable operation. For powder applications, the ZXD incorporates a 10-chamber open-end D-Rotor, designed with a specialized blow-through channel that maximizes pocket sweeping, further enhancing its capability to handle bulk materials with precision and efficiency.
