The DW Series Cryogenic Solenoid Valve is a premier control valve specifically engineered and highly customized for deep refrigeration, ultra-low temperature freezing equipment, cold chain transport logistics, and various industrial fluid loops conveying cryogenic media such as refrigerants. Covering a comprehensive size spectrum from DN15 to DN50, this series boasts an ultra-compact, streamlined geometric profile. While significantly optimizing spatial utilization, 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 and medium-to-high differential pressure working conditions. The valve delivers exceptional responsiveness, minimal pressure drop, and rapid open/close cycling within a reliable 0.4 to 10 bar pressure range. To withstand rigorous operating environments, the valve bodies are meticulously manufactured from high-toughness SS304 Stainless Steel, ensuring universal compatibility with 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 100 to 50 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 absolute zero, entirely eliminating the catastrophic risk of low-temperature cold-embrittlement or fracturing common in conventional alloys.

Versatile Industrial Connections and Compact Envelope: Broadly available from DN15 up to DN50, 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.

Superior Flow Capacity and Wide-Range Pressure Stroke: The internal pilot geometries are calculated via precise fluid dynamics to enforce swift actuation strokes. It performs sharp, instantaneous open/close cycles across the 0.4 to 10 bar spectrum, ensuring extensive high-flow capacity while driving pressure drops and cooling loss down to absolute minimums.

Premium Metallurgy for Clean Refrigerant Environments: The SS304 stainless steel offers exceptional machining accuracy alongside phenomenal chemical compatibility and rust-washout resistance against Freon, liquid CO2, eco-friendly refrigerants, and industrial neutral cryogenic agents.

Advanced Low-Temperature Cryo-Sealing Technology: The internal seal rings and seat interfaces incorporate specialized 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.
