ZXQ

Product catalog summary

Overview: The document provides technical specifications and features of the ZXQ series rotary valves, designed for handling powders in compounding, extrusion, and materials handling applications. The series includes models ZXQ 300 to ZXQ 700, each with varying dimensions and capabilities.

Specifications:

Pressure Range: The rotary valves operate at a system and differential pressure of 3.5 bar (51 psi) and are pressure surge proof up to 10 bar (145 psi) due to their heavy-duty design.
Design Features: The valves feature a large inlet without cross-section restriction, outboard bearings separated by a purged seal arrangement, and a blow-through channel for optimal pocket sweeping at low pressure drop.
Rotor Design: The open-end high-pressure rotor has 14 pockets and does not require an additional sealing system, ensuring low maintenance.

Options and Accessories:

Chamfered blades
Suitability for Ex-zones (ATEX)
Heated housing by steam or thermo-oil up to a maximum of 220°C
Chain drive or direct drive options
Leakage gas collector

Performance and Leakage Gas Diagrams:

The performance diagram illustrates the handling of powders with a bulk density of 1000 kg/m³ and particle sizes ranging from 0.075 mm to 0.6 mm at a differential pressure of 2 bar.
The leakage gas diagram provides data on leakage rates with and without product at standard clearance and maximum speed.

Dimensions and Mounting:

The document lists detailed dimensions for each model, including inlet, blow-through channel, and mounting pattern dimensions, with weights varying depending on the installed drive.
Dimensions are provided in millimeters and drilled according to DIN PN 10 or ANSI 150 lbs standards.
