As a professional manufacturer with a strong foothold in the global marine industry, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T3191-92 Marine Ball Valve. Engineered specifically for demanding shipboard environments, this valve offers a reliable and robust solution for controlling gas and water flow on vessels. With our commitment to quality under the ISO9001 framework and years of experience since our establishment in 2016, we deliver valves that meet stringent maritime standards, ensuring safety and operational efficiency for shipbuilders and fleet operators worldwide.
This male-threaded marine ball valve is designed to provide secure sealing and easy operation in the harsh conditions at sea. Its construction prioritizes durability and corrosion resistance, critical factors for any marine application.
Key Features and Technical Advantages:
- Compliant Design: Manufactured strictly in accordance with the Chinese Ship Standard CB/T3191-92, ensuring compatibility and reliability for shipbuilding and repair projects.
- Robust Construction: Typically constructed from high-grade materials such as cast steel or stainless steel, offering excellent resistance to corrosion from saltwater and marine atmospheres.
- Secure Threaded Connection: The male threaded ends (NPT or BSPT threads are common) provide a strong, leak-proof connection to piping systems, simplifying installation and maintenance.
- Quarter-Turn Operation: Features a simple lever handle for quick and easy open/close operation, which is crucial during emergencies or routine system adjustments onboard.
- Bubble-Tight Seal: The precision-machined ball and seats (often PTFE) ensure a bubble-tight shut-off, preventing any leakage of gas or water, which is vital for system safety and conservation.
- Versatile Service: Approved for use with both gas and water services on ships, making it a versatile component for various shipboard systems like fuel lines, bilge systems, freshwater lines, and compressed air systems.
- Low Maintenance: The simple design with minimal moving parts translates to reduced maintenance requirements and long service life, lowering the total cost of ownership.

Frequently Asked Questions (FAQ):
-
Q: What does "CB/T3191-92" mean for this valve?
A: CB/T3191-92 is a Chinese national professional standard specifically for shipbuilding. Valves manufactured to this standard are designed and tested to meet the performance and safety requirements for use on ships and marine platforms. -
Q: Can this valve be used for both gas and liquid services on a ship?
A: Yes, as indicated in the title, this marine ball valve is designed and suitable for both gas and water service applications onboard vessels, such as fuel gas lines, fresh water systems, and bilge lines. -
Q: What are the common thread standards for the male threaded ends?
A: The male threads are typically manufactured to NPT (American National Pipe Taper) or BSPT (British Standard Pipe Taper) standards. The specific standard can be confirmed based on your regional requirements or project specifications. -
Q: What material options are available to resist seawater corrosion?
A: For superior corrosion resistance in marine environments, we recommend materials like Stainless Steel 304 (CF8) or 316 (CF8M). Bronze is also a common and effective choice for seawater applications. -
Q: Is this valve suitable for high-pressure applications?
A: This valve is designed for standard shipboard pressure ratings. For high-pressure applications, it is crucial to provide the specific pressure class requirement so we can verify suitability or recommend an alternative model. -
Q: Do you offer different handle types or locking mechanisms?
A: While a standard lever handle is common, options such as a locking handle (for safety in critical applications) or a handwheel may be available. Please inquire about customizable features. -
Q: What is the lead time for an order, and what are the payment terms?
A: Lead time depends on the order quantity and material specifications. Standard items typically have shorter lead times. We offer flexible payment terms, including T/T and L/C, which can be discussed in detail after receiving your inquiry. -
Q: Do you provide certification or test reports with the valves?
A: As an ISO9001 certified manufacturer, we conduct rigorous quality checks. Standard test reports (like pressure tests) can be provided upon request. Specific certification requirements should be discussed during the order process.
