The CDW Series Cryogenic Stainless Steel Solenoid Valve is a premier control valve specifically engineered and highly customized for air separation units, ultra-low temperature laboratories, medical flash-freezing equipment, superconducting technology, and various industrial fluid loops conveying extreme cryogenic media such as liquid nitrogen and liquid oxygen. Covering a specialized small-bore spectrum from DN6 to DN10, this series boasts an ultra-compact, streamlined geometric profile. While significantly optimizing spatial utilization for small-flow systems, it fully supports and complies with both threaded and flanged connection standards, greatly facilitating quick on-site installation, quick assembly, and seamless adaptation within diverse international piping networks. The internal flow channels and sealing pairs have undergone deep fluid-dynamics and materials optimization specifically calibrated for ultra-low temperatures of minus 196 degrees Celsius and zero differential pressure startup capability. The valve delivers exceptional responsiveness, minimal pressure drop, and rapid open/close cycling within a reliable 0 to 8 bar pressure range. To withstand rigorous cryogenic environments, the valve bodies are meticulously manufactured from high-toughness SS304 Stainless Steel, ensuring universal compatibility with extreme cryogenic liquids and gases. It achieves absolute structural integrity and optimal gas-tightness during long-term high-frequency operations, making it an ideal, high-efficiency control component for modern automated cryogenic fluid loops and modular skid designs.

Feature

Extreme Cryogenic Resilience and Low-Temperature Anti-Brittleness: Purpose-built for the harsh thermal spans of minus 196 to 56 degrees Celsius. Meticulously formed from high-toughness SS304 stainless steel, the valve structure retains superb tensile strength and impact resistance even at deep temperatures approaching the boiling point of liquid nitrogen, entirely eliminating the catastrophic risk of low-temperature cold-embrittlement or fracturing common in conventional alloys.

Zero Differential Pressure Direct-Acting Mechanism: Utilizing a highly reliable direct-acting drive structure, the opening and closing of the valve do not rely on the medium pressure of the pipeline itself. Even if the system is at zero differential pressure, vacuum, or micro-pressure status, the energized coil can immediately lift the valve core for a clean and sharp open, perfectly solving the chronic sticking issues under low-pressure or static conditions.

Versatile Industrial Connections and Compact Envelope: Broadly available from DN6 up to DN10 for micro and fine-flow control, providing both durable threaded joints and high-integrity flanged interfaces to cater to varied field sealing protocols while successfully compacting the longitudinal and lateral spatial footprints.

Premium Metallurgy for Clean Cryogenic Environments: The SS304 stainless steel offers exceptional machining accuracy alongside phenomenal chemical compatibility and rust-washout resistance against liquid nitrogen, liquid oxygen, liquid argon, industrial neutral cryogenic agents, and high-purity cryogenic fluids with zero medium contamination.

Advanced Low-Temperature Cryo-Sealing Technology: The internal seal rings and seat interfaces incorporate specialized ultra-low temperature composite compounds. They preserve outstanding physical elasticity and deformation recovery under severe cryo-cycling, thoroughly solving the chronic issues of internal leakage or frost-jamming found in standard elastomers and securing long-term leak-proof sealing.
