PRODUCT SHEET

An innovative sealing system and high-pressure H-Rotor design work together to deliver durable, precise, and maintenance-friendly performance.

Innovative Design for Optimal Functionality and Efficiency

The innovative design is complemented by a premium sealing system, which includes a floating sealing cassette and locking gas, further enhanced by a labyrinth ring for optimal performance. The valve's outboard bearings and a dedicated drop-out opening, separate from the product area, facilitate easy detection of gasket failures, ensuring reliability and maintenance efficiency. Additionally, the 12-chamber closed-end H-Rotor is expertly designed for discharging and conveying materials into pneumatic systems at pressures of up to 3.5 bar. The end plates are encircled by a robust ring that serves as the contact surface for a radial seal, reinforcing the ZVH's commitment to durability and precision in operation.
