As a professional manufacturer specializing in industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Marine Low Temperature Ball Valve, engineered specifically for extreme cryogenic applications down to -196°C. This valve is a critical component for the safe and efficient operation of LNG (Liquefied Natural Gas) systems, marine fuel handling, and other low-temperature processes. Our focus on precision manufacturing under the ISO9001 framework ensures a product that delivers reliable shut-off, exceptional durability in harsh environments, and contributes to the overall safety and performance of your cryogenic infrastructure.
Understanding the stringent demands of cryogenic service is paramount. Materials must withstand extreme thermal contraction without failure, seals must maintain integrity, and operational mechanisms must function flawlessly even at temperatures where many materials become brittle. Our valve is designed to meet these challenges head-on, offering a robust solution for engineers and operators in the LNG, petrochemical, and marine sectors.
Core Features & Technical Advantages:
- Extended Temperature Performance: Specifically validated for continuous service from ambient conditions down to -196°C (-320°F), covering the full range of LNG storage and transfer temperatures.
- Material Integrity: Utilizes specially selected stainless steels, carbon steels, or alloy steels with low-temperature toughness properties to prevent cracking or deformation under thermal stress.
- Enhanced Sealing System: Features advanced PTFE or specially compounded polymeric seals designed for cryogenic environments, ensuring zero leakage even after prolonged exposure to extreme cold.
- Extended Stem Design: Incorporates a long stem extension to isolate the operating mechanism (actuator or handwheel) from the cold zone, protecting components and ensuring smooth operation.
- Robust Construction: The ball, stem, and body are machined to high tolerances, providing a tight shut-off and minimizing internal clearances that could lead to ice formation or operational issues.
- Versatile Actuation: Available for manual operation or can be configured for pneumatic, electric, or hydraulic actuation based on system requirements.
- Fire Safe Design Option: Certain models can be equipped with fire-safe features as per API standards, providing an additional layer of safety.
- Anti-Static & Blow-Out Proof Stem: Design features often include an anti-static stem and a blow-out proof mechanism to enhance safety in critical applications.

Frequently Asked Questions (FAQ):
-
Q: What is the primary application for this -196°C Cryogenic Ball Valve?
A: Its primary application is in LNG (Liquefied Natural Gas) systems, including storage tanks, loading/unloading lines, processing units, and marine fuel systems. It is also suitable for other industrial cryogenic processes involving ethylene, liquid nitrogen, or other ultra-low temperature fluids. -
Q: How does the valve handle thermal contraction and potential leakage at such low temperatures?
A: The design incorporates materials with suitable low-temperature toughness to minimize thermal stress. The sealing system uses polymers specifically engineered for cryogenic service, which maintain their sealing properties and flexibility even at -196°C. The extended stem design also helps manage thermal gradients. -
Q: Can this valve be used with actuators for remote or automated control?
A: Yes, it is designed to be compatible with various actuators. We can supply the valve configured with pneumatic, electric, or hydraulic actuators based on your control system requirements. -
Q: What are the available pressure ratings and size ranges?
A: Standard pressure ratings include ANSI Class 150, 300, and 600 (or equivalent DIN/PN classes). The size range typically covers from DN15 (1/2 inch) up to DN300 (12 inches). Specific sizes and ratings outside this range can be discussed for custom orders. -
Q: Does the valve come with any specific certifications?
A: Our manufacturing process is certified under the ISO9001 Quality Management System, ensuring consistent quality control. The valve itself can be supplied with standard manufacturing test reports (shell test, seat test). Specific product certifications like CE, API, or others can be addressed upon request for applicable models. -
Q: What is the typical lead time for orders?
A: Lead time depends on the specification, quantity, and whether it's a standard or custom model. For standard configurations, lead times can be relatively short. We provide estimated lead times upon receipt of your detailed inquiry. -
Q: How does Shanghai Zhibang ensure quality for such a critical component?
A> Quality is ensured through our ISO9001 certified manufacturing system, which governs material selection, machining processes, assembly, and testing. Critical valves undergo additional performance testing, including cryogenic cycle testing where applicable. -
Q: Can you provide support for installation or technical integration?
A: We provide detailed technical documentation, including installation manuals and dimensional drawings. For complex integration questions, our engineering team is available for technical consultation.
