ZAQ

Product catalog summary

Overview: The document provides technical specifications and features of the ZAQ series rotary valves, designed for handling powders in compounding, extrusion, and materials handling applications. It highlights the design, performance, and optional accessories available for these valves.

Specifications:

Pressure Range: The rotary valves operate at a system and differential pressure of up to 3.5 bar (51 psi) and are pressure surge proof up to 10 bar (145 psi).
Design Features: The valves feature chamfered blades, are suitable for Ex-zones (ATEX), and have a heated housing capable of reaching up to 220°C using steam or thermo-oil.
Drive Options: Available with chain drive or direct drive.
Leakage Gas Management: Equipped with a leakage gas collector and feeding shoe to minimize gas escape.

Options and Accessories:

Cast housing with double wall execution.
High pressure Q-Rotor with open end and 14 pockets.
Labyrinth ring, O-Ring, and purge connection for enhanced sealing.
Shaft seal, outboard bearing, and drop out opening for maintenance ease.

Performance and Dimensions:

The valves are designed with large inlet and outlet cross-sections to maximize product capacity while minimizing leakage gas.
External bearings are separated from the product by a purged seal arrangement.
Dimensions vary by model (ZAQ 300, ZAQ 500, ZAQ 600) with specific inlet/outlet sizes and weights provided.

Performance Diagrams:

Includes diagrams showing leakage gas rates with and without product at various differential pressures.
Performance is illustrated for powders with specific bulk densities and particle sizes.
