Our companyProduct OverviewThe cryogenic valve from Yantai Oceanblue Refrigeration Engineering Co., Ltd. is engineered for safe, reliable control of low-temperature media in cryogenic containers and pipeline systems. Designed to handle liquefied gases-including LNG, liquid oxygen (LOX), liquid nitrogen (LN), and liquid argon (LAr)-this valve maintains tight shut-off and smooth operation across a wide service temperature range of ?196oC to +80oC. With a rated working pressure of 4.0 MPa and size options from DN10 to DN100, it meets the demanding requirements of industrial gas, energy, chemical, and refrigeration applications.Materials & ConstructionTo perform under extreme cold, the valve employs a carefully selected materials system. The valve body and bonnet are CF8 stainless steel, providing strength, corrosion resistance, and dimensional stability at low temperatures. The stem and bonnet hardware are 304 stainless steel, balancing toughness and processability. For seating, we use PCTFE (Polychlorotrifluoroethylene)-a proven cryogenic sealing material with excellent cold-flow resistance, low gas permeability, and long-term dimensional stability. This combination ensures dependable sealing, minimal leakage, and extended service life in cryogenic service.Low-Temperature Design FeaturesCryogenic service introduces unique mechanical and thermal challenges. Our valve addresses these with a series of design solutions:Extended Cold-Zone Isolation (Long-neck/extended bonnet option) positions the packing away from the coldest region, helping preserve packing elasticity and reducing the risk of frost interference at the gland.Precision Stem Finish and Guided Trim minimize friction and ensure consistent torque, even after repeated thermal cycling.Optimized Seat Geometry with PCTFE provides bubble-tight shut-off while resisting cold-flow under differential pressure.Thermal Contraction Considerations are built into critical tolerances to maintain reliable engagement between seat and closure at cryogenic temperatures.Process Cleanliness & Quality AssuranceFor oxygen and other high-purity applications, component cleanliness is critical. All wetted parts of the valve undergo uniform degreasing and de-oiling treatment prior to assembly to reduce ignition risks and contamination. Every valve is 100% factory tested for shell strength, seat tightness, and operational performance within its rated conditions. Traceability is maintained from raw material selection through final inspection to support long-term reliability and compliance needs.Operating ParametersMedia: LNG, LOX, LN, LAr (and other compatible low-temperature media)Temperature Range: ?196oC to +80oCWorking Pressure: 4.0 MPaSize Range: DN10-DN100Body/Bonnet: CF8 stainless steelStem/Bonnet Hardware: 304 stainless steelSeat/Seal: PCTFEEnd Connections: Options available upon request (e.g., flanged, welded, threaded), depending on size and application.ApplicationsLNG receiving, storage, and boil-off gas (BOG) handling in energy terminals and satellite stationsAir separation units (ASUs) for LOX, LN, and LAr production, storage, and distributionIndustrial gas logistics, including cryogenic tankers, micro-bulk, and on-site supply systemsRefrigeration and cooling processes requiring low-temperature control valves in research labs, food processing, or specialty chemical linesTest stands and pilot plants where precise, repeatable shut-off and throttling under cryogenic conditions are essentialPerformance & BenefitsSecure Shut-off: PCTFE seat and precise trim achieve reliable sealing at cryogenic temperatures.Durable Construction: CF8 body and 304 stem provide corrosion resistance and mechanical stability over the full temperature envelope.Clean for Oxygen Service: Degreased wetted parts reduce contamination risks for LOX and high-purity gas duties.Versatile Sizing: DN10-DN100 coverage fits both instrumentation lines and larger process headers.Ease of Operation: Smooth torque characteristics and guided stem design support consistent manual or actuated operation.Quality Verified: 100% factory testing ensures each valve meets pressure, sealing, and functional criteria before shipment.Options & CustomizationTo match specific project requirements, the following options can be provided upon consultation:Extended bonnet lengths to suit insulation thickness and ambient conditionsActuation choices including manual handwheel, pneumatic actuator, or electric actuator with limit switches and position feedbackEnd connection standards (e.g., GB, DIN, ANSI/ASME) and facing types suitable for your pipeline specificationInstrumentation accessories such as stem extensions, locking devices, and position indicatorsDocumentation packages including test records and material reports as required by project specificationsInstallation & Maintenance GuidanceFor best performance, install the valve in accordance with cryogenic piping practices. Ensure adequate insulation and vapor barrier around cold sections, while keeping the packing area accessible and above the frost line when using an extended bonnet. Prior to commissioning, flush and dry the pipeline to remove particles and moisture; verify that the media compatibility matches the valve's materials of construction. During operation, follow recommended torque/actuation settings to prevent seat damage. Periodic inspection of packing tightness and seat condition will help maintain long-term tightness. If service conditions change (media, temperature, or pressure), consult Yantai Oceanblue Refrigeration Engineering Co., Ltd. for guidance on suitability.Why Choose Yantai OceanblueWith manufacturing and application experience in low-temperature and industrial refrigeration systems, Yantai Oceanblue Refrigeration Engineering Co., Ltd. provides valves and components that prioritize safety, cleanliness, and durability.
