The ZVD is designed for maximum capacity and a gentle product transfer.

Discharging Valve For Fine And Coarse-grained Products

The ZVD is engineered for maximum capacity, achieved through an optimal ratio of rotor volume to inlet cross-section. This design ensures efficient material flow while maintaining high performance standards. The valve incorporates a specially designed inlet geometry that is purpose-built for gentle product handling, minimizing the risk of damage to sensitive materials during transfer. Additionally, the integrated feeding shoe enhances versatility, allowing the valve to effectively feed bulk materials into pneumatic conveying systems at pressures of up to 1.5 barg (21 psi). Experience unparalleled efficiency and reliability in your material handling processes with our innovative rotary valve solution.

Special Inlet Geometry

The ZVD is distinguished by its specially designed inlet geometry, which is purpose-built for gentle product handling and effective anti-chopping, ensuring the integrity of sensitive materials. Complementing this design is a premium sealing system featuring double shaft seals and a labyrinth ring, specifically engineered for gas purging in powder applications. Additionally, the ZVB incorporates a 10-chamber open-end D-Rotor, optimized for both powder and granular materials, facilitating efficient discharge and conveying of bulk materials into pneumatic systems at pressures of up to 1.5 bar. This combination of features not only enhances operational efficiency but also preserves the quality of the materials being processed.
