ZVB

Product catalog summary

Overview: The document provides technical specifications and features of the Rotary Valve ZVB, designed for handling pellets in compounding and extrusion processes. It highlights the valve's capabilities, options, and accessories.

Specifications:

Pressure Range: Operates at a system and differential pressure of 1.5 bar (21 psi).
Pressure Surge Proof: Can withstand up to 10 bar (145 psi) due to its heavy-duty design.
ATEX Compliance: Optional usage in Ex-Zones for explosive environments.
Temperature Range: High-temperature version available, supporting up to 250°C.

Design Features:

Quick Coupling: Equipped with an extraction device for easy maintenance.
Rotor Design: Features shallow pockets and a B-Rotor closed end with 10 pockets for pellet applications.
Inlet Geometry: Anti-chopping design for safe starting below a full product column.
Body Vent: Enhances filling efficiency through internal leakage gas venting.

Options and Accessories:

Chain drive or direct drive options.
Leakage gas hopper and feeding shoe available.
Wear protection and pellet deflection (ZG version).

Performance and Dimensions:

Performance diagrams indicate leakage gas rates and rotor speeds.
Dimensions vary based on the model, with detailed measurements provided for each size from ZVB 200 to ZVB 800.

Applications: Suitable for handling PE/PP pellets with a bulk density of 520 kg/m³ and a particle size of 3 mm, operating at a differential pressure of 0.8 bar.
