Series CG

Product catalog summary

Overview: The document outlines the technical specifications and features of the Series CG Clean Break Couplings and Cartridge Coupling Elements, which are used in cooling water applications across railway technology, air conditioning, and military sectors.

Specifications:

Nominal sizes available: 6, 9, 12, 16, 20, and 25 mm.
Maximum static operating pressure: 16 bar (232 psi).
Operating temperature range: -50°C to +85°C (-58°F to +185°F).
Flow rate varies by type, e.g., CG-G16 has a Cv of 9.1.
Maximum permissible misalignment: ± 2 mm.

Features and Benefits:

Constructed from lightweight anodized or hard-coated aluminum.
High flow rate and vibration resistance as per EN 61373, Cat. 1-3, Cl. B.
Self-sealing valves on both sides to reduce residual leakage.
Optimized seals using VMQ/FKM materials and stainless steel springs.
Dirt protection for larger sizes (16, 20, 25 mm).

Options and Accessories:

Stainless steel versions with anti-twist and dust protection.
Custom connection variants, including flange connections and 90° angles.
Available with hose attachments.
Pressure relief valve option at 1.5 bar (22 psi).

Applications: These couplings are ideal for cooling circuits in light rail cars and are suitable for air conditioning and military applications due to their robust design and high performance.

Performance Diagram: A performance diagram is included, showing flow rates and pressure differences for various coupling types, tested with water at 20°C according to DIN standards.

Additional Information:

WALklick quick fit couplings are available for larger quantities, with nominal sizes of 3, 7, 10, 15, and 19 mm, and can be supplied with hoses.
