As a professional manufacturer with a strong commitment to quality and innovation, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our Low Temperature Ball Valve CB/T3191. Engineered for demanding cryogenic applications, this stainless steel, full port valve is designed to ensure reliable, leak-free performance in environments where conventional valves fail. Since our establishment in 2016, we have focused on developing valves that meet the rigorous standards of global markets, exporting to regions including North America, Europe, and Southeast Asia. Our ISO9001-certified manufacturing processes guarantee that every valve delivers the durability and precision our customers depend on for their critical low-temperature systems.
This valve is specifically constructed to handle the challenges posed by liquefied gases and other cryogenic fluids. Its robust design prevents thermal contraction issues and maintains sealing integrity under extreme cold, offering a solution that enhances system safety and operational efficiency.
Key Features and Technical Advantages:
- Superior Material Construction: Manufactured from high-grade stainless steel, the valve body and components offer excellent resistance to corrosion and thermal stress, ensuring long service life even in harsh, low-temperature environments.
- Full Port Design: Provides an unobstructed flow path with minimal pressure drop, which is crucial for maintaining system efficiency and flow rates in cryogenic transfer applications.
- Extended Stem Design: A specially designed extended stem prevents frost formation at the packing area, keeping the operating mechanism accessible and functional at very low temperatures.
- Advanced Sealing Technology: Utilizes low-temperature resistant seat materials such as reinforced PTFE, which retain flexibility and sealing properties to prevent leakage down to cryogenic levels.
- Precision Machining: All components are precision-machined to ensure tight tolerances, smooth operation (quarter-turn), and a perfect seal in both open and closed positions.
- Versatile Connection Options: Available with threaded or flanged ends to suit various piping system requirements, facilitating easy installation and integration.

Frequently Asked Questions (FAQ):
-
Q: What is the minimum operating temperature this valve can handle?
A: The valve is designed for cryogenic service and can typically operate reliably at temperatures as low as -196°C (liquid nitrogen temperature), depending on the specific seat material selected. -
Q: Is the full port design necessary for all applications?
A: The full port design is particularly advantageous for applications requiring minimal pressure drop and high flow capacity, such as in transfer lines for LNG, liquid oxygen, or other cryogenic fluids. For systems where pressure drop is less critical, standard port valves may be considered. -
Q: What are the available end connections?
A: We offer threaded connections (like NPT or BSP) and flanged connections (RF or FF face) to match different piping standards. The specific type can be customized based on your project specifications. -
Q: How does the extended stem design benefit operation in low temperatures?
A: The extended stem moves the packing and operating mechanism away from the extremely cold valve body, preventing ice or frost buildup that could freeze the handle and make the valve inoperable. -
Q: Are these valves suitable for oxygen service?
A: With proper material selection (such as stainless steel and specially cleaned components), these valves can be configured for oxygen service. It is crucial to inform us of this requirement so we can provide a valve manufactured and cleaned to the appropriate standards. -
Q: What is the lead time for an order?
A: Lead times vary based on order quantity, size, and customization. Standard sizes from DN15 to DN80 typically have shorter lead times. Please contact our sales team for a precise delivery schedule. -
Q: Do you provide pressure testing certificates?
A: Yes, each valve undergoes rigorous pressure and leak testing before shipment. Relevant test reports can be provided upon request to meet your quality documentation needs. -
Q: Can I get a sample valve for testing?
A: Sample valves are available for qualified buyers. Please reach out to discuss sample availability, terms, and associated costs.
