As a dedicated manufacturer of industrial valves since our establishment in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our specialized 304 Stainless Steel Marine Ball Valve, engineered for reliable performance in extreme low-temperature environments down to -196°C. Our extensive experience in exporting to diverse global markets, including North America, Southeast Asia, and Europe, has equipped us with the knowledge to produce valves that meet the stringent demands of marine, LNG, and cryogenic applications. This valve is a testament to our commitment to quality, durability, and operational safety in the harshest conditions.
This cryogenic ball valve is designed to provide a secure and long-lasting sealing solution for systems handling liquefied gases and other ultra-cold media. Constructed from high-grade 304 stainless steel, it offers excellent corrosion resistance, which is crucial for marine environments. The valve's extended stem design is a critical feature for low-temperature service, ensuring that the sealing components and operating mechanism remain at ambient temperature, preventing freeze-up and guaranteeing smooth operation even at -196°C. Key technical specifications and advantages include:
- Superior Low-Temperature Toughness: The 304 stainless steel body and specially selected seat materials (like PTFE or reinforced polymers) maintain their mechanical properties and sealing integrity without becoming brittle at cryogenic temperatures.
- Extended Bonnet Design: This design creates a thermal barrier, keeping the stem packing and actuator at a higher, safer temperature. This prevents ice formation on the stem and allows for easy operation in cold environments.
- Bubble-Tight Shut-off: The precision-machined ball and seat provide a reliable, bubble-tight seal, essential for containing expensive or hazardous cryogenic fluids and maintaining system pressure.
- Versatile Configuration: Available in a full range of sizes and connection types to fit various piping systems. Actuation options provide flexibility for remote or automated control.
- Robust Construction: Built to withstand not only thermal stress but also vibration and pressure fluctuations common in marine and industrial settings.
For our clients, this translates into significant operational benefits: reduced risk of leaks and failures, lower maintenance costs due to durable construction, enhanced safety for personnel and equipment, and reliable long-term performance that protects your capital investment.

Frequently Asked Questions (FAQ):
Q1: What makes this valve suitable for -196°C service compared to a standard ball valve?
A1: Standard valves can fail at cryogenic temperatures due to material embrittlement and seal failure. This valve uses an extended bonnet to isolate cold fluid from the stem seal, and materials like 304 SS and specialized PTFE seats that retain flexibility and strength at extreme lows.
Q2: Can this valve be used for LNG (Liquefied Natural Gas) applications?
A2: Yes, it is well-suited for LNG and other liquefied gas services where temperatures can drop below -160°C. The design and material selection are aligned with the requirements for such cryogenic processing and storage systems.
Q3: Are different actuator options available for automated operation?
A3: Absolutely. The valve can be fitted with pneumatic (air), electric, or hydraulic actuators upon request. We can provide a complete package including the actuator, brackets, and necessary controls.
Q4: What are the standard pressure ratings offered?
A4: Standard pressure classes include PN16, PN25, and PN40 (approximate to ANSI Class 150 and 300). Higher pressure ratings can be engineered based on specific project requirements.
Q5: How do you ensure leak-proof performance at such low temperatures?
A5: We employ precision machining for the ball and seat, high-integrity welding for extended components, and rigorous cold testing protocols. Each valve undergoes pressure and, when specified, low-temperature helium leak testing to verify bubble-tight sealing.
Q6: Is the valve compliant with specific marine or industry standards?
A6: The valve is manufactured in accordance with design standards like API 608 and BS 5351. Certifications such as fire-safe API 607/6FA, NACE MR0175, or specific marine society approvals (e.g., DNV, ABS) can be provided as optional extras.
Q7: What is the typical lead time for an order?
A7: Lead time depends on order quantity, size, and configuration. Standard sizes and specs generally have shorter lead times. Please contact our sales team with your specific requirements for an accurate delivery schedule.
Q8: Do you provide technical support and after-sales service?
A8: Yes, our technical team is available to assist with selection, installation, and troubleshooting. We also provide comprehensive documentation, including dimensional drawings, material certificates, and test reports.
