Core Advantages: Solving Critical Cryogenic Flow Control Pain Points
In cryogenic applications, even minor valve malfunctions can lead to costly downtime, safety hazards, or product loss. The ODKV Series is engineered to address these challenges head-on, with three core advantages that set it apart from standard globe valves:
1. Zero Leakage Reliability in Extreme ColdCryogenic systems demand absolute sealing integrity to prevent gas boil-off and environmental risks. The ODKV Series features a dual-seal design—combining a precision-machined metal backup seat with a low-temperature optimized polymer primary seat—that ensures bubble-tight shutoff (API 598 leakage Class VI) even at -196°C. Unlike conventional valves that experience seal hardening or shrinkage in deep freeze, our seat materials are formulated to maintain elasticity and contact pressure, eliminating the risk of fugitive emissions.
2. Thermal Shock Resistance & Structural IntegrityRapid temperature changes (thermal shock) are a major cause of valve body cracking and stem seizure in cryogenic service. The ODKV Series’ body is forged from cryogenically tested alloys (LCB, 316L) that undergo sub-zero tempering to eliminate internal stress. Its extended bonnet design creates a thermal barrier between the cold valve body and the ambient-temperature actuator/handwheel, preventing ice formation on operating components and ensuring smooth operation in the harshest conditions. For ultra-low-temperature LNG applications, we offer extended bonnet lengths up to 300mm, fully customizable to your insulation requirements.
3. Low Maintenance, Long Service LifeFor industrial facilities operating 24/7, valve maintenance is a logistical and financial burden. The ODKV Series minimizes downtime with a top-entry design that allows for in-line servicing of seats, stems, and packing—no need to remove the valve from the pipeline. Additionally, the pressure-balanced disc design reduces operating torque by up to 40% compared to standard globe valves, extending the life of actuators and reducing wear on moving parts. All critical components are corrosion-resistant, making the valve ideal for both coastal LNG terminals and inland petrochemical plants.
Technical Details: Precision Engineering for Cryogenic Excellence
Every component of the ODKV Series is engineered with cryogenic service in mind, from material selection to design geometry, ensuring uncompromising performance in extreme conditions.
Material Science for the Deep Freeze
The valve’s body and bonnet are constructed from low-temperature certified alloys to avoid brittle fracture. LCB carbon steel is the cost-effective choice for temperatures down to -46°C, while 304L/316L stainless steel and Alloy 400 deliver superior corrosion resistance for acidic cryogenic media and saltwater environments (e.g., offshore LNG terminals). The stem is made from 17-4 PH stainless steel, heat-treated to achieve a tensile strength of 1030 MPa, with an anti-blowout design that eliminates the risk of stem ejection under pressure—a critical safety feature for high-pressure cryogenic systems.
Innovative Design Highlights
• Pressure-Balanced Disc: Reduces hydrodynamic forces on the disc, enabling easier operation and consistent flow control across the entire pressure range. This design is particularly valuable for large-diameter valves (DN150+) used in LNG pipeline transmission.
• Low-Torque Packing System: The stem packing features a multi-layer PTFE design with a graphite anti-extrusion ring, ensuring low friction and zero leakage even after thousands of cycles. This system is compatible with both manual and automated operation, eliminating the need for frequent packing adjustments.
• Gear-Operated Handwheel (DN100+): For larger valves, the heavy-duty gear operator provides mechanical advantage, making manual operation effortless even in low-temperature conditions where gloved hands may reduce dexterity. Electric and pneumatic actuators are available with ATEX, IECEx, and NEMA 4X certifications for hazardous locations.
Application Scenarios: Versatile Performance Across Critical Industries
The ODKV Series Cryogenic Globe Valve is designed to meet the rigorous demands of diverse industrial sectors where low-temperature flow control is non-negotiable. Its adaptability and reliability make it the preferred choice for:
1. LNG Industry (Liquefied Natural Gas)
From liquefaction plants and storage tanks to regasification terminals and pipeline transportation, the ODKV Series is the backbone of LNG flow control. It is widely used in feed gas conditioning, cryogenic separation, and LNG loading/unloading systems, withstanding the extreme cold of -162°C and the high pressures of pipeline transmission.
2. Industrial Gases
For the production, storage, and distribution of cryogenic industrial gases (LOX, LIN, LAR), the ODKV Series ensures pure, contamination-free flow. The metal seat option (Inconel 625) is ideal for high-purity applications, as it eliminates the risk of polymer particle contamination in semiconductor and pharmaceutical gas supply systems.
3. Petrochemical & Chemical Processing
In petrochemical plants, the valve controls cryogenic hydrocarbons (ethylene, propane, butane) used in polymerization processes and refrigerant systems. Its corrosion-resistant materials make it suitable for acidic cryogenic media, while its thermal shock resistance ensures reliability in batch processing applications with rapid temperature cycles.
4. Energy & Power Generation
Liquefied natural gas-fired power plants rely on the ODKV Series for fuel gas conditioning and cryogenic cooling systems. It is also used in hydrogen storage facilities (liquid hydrogen at -253°C) for fuel cell and clean energy applications, with custom alloy options available for hydrogen compatibility.
Maintenance Convenience: Minimizing Downtime, Maximizing Productivity
We understand that unplanned downtime costs your business time and money. The ODKV Series is designed for ease of maintenance, with features that reduce service time and labor costs:
• Top-Entry Servicing: All internal components (seat rings, disc, stem, packing) are accessible from the top of the valve, allowing for in-line repair and replacement without disconnecting the valve from the pipeline. This feature can reduce maintenance time by up to 70% compared to side-entry or welded valves.
• Standardized Components: Critical wear parts (seats, packing, gaskets) are manufactured to industry standards (API 600, ASME B16.34), ensuring easy availability and interchangeability worldwide—essential for global projects and remote locations.
• Minimal Lubrication Requirements: The low-torque packing system and corrosion-resistant materials eliminate the need for frequent lubrication, reducing routine maintenance tasks and ensuring consistent performance in hard-to-reach areas (e.g., cryogenic storage tanks).
