As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. is dedicated to providing reliable and durable fluid control solutions for the global marine industry. Our Stainless Steel CB/T3191 Ball Valve is engineered specifically for the demanding environment of seawater cooling systems on vessels, where corrosion resistance and long-term performance are critical. With over 7 years of experience since our establishment in 2016, we understand the challenges faced by shipbuilders and operators, and this valve is our answer to ensuring system integrity and minimizing maintenance downtime. We export to major markets worldwide, including North America, Europe, and Southeast Asia, demonstrating our commitment to international quality standards and customer satisfaction.
This specialized ball valve is designed to handle the corrosive nature of seawater while providing precise flow control. The core of its reliability lies in the high-grade stainless steel construction, which offers excellent resistance to pitting and crevice corrosion. The valve body and ball are precision-machined to ensure a tight seal and smooth operation over thousands of cycles. We offer a range of configurations to suit different piping layouts and operational requirements on board various types of vessels.
Key Technical Features and Specifications:
- Corrosion-Resistant Construction: Manufactured from 304 or 316 stainless steel, providing superior resistance to saltwater corrosion, chlorides, and other harsh marine elements.
- CB/T3191 Compliance: Designed and tested in accordance with the Chinese CB/T3191 standard for marine valves, ensuring compatibility with marine engineering specifications.
- Robust Sealing System: Features advanced seat materials like PTFE or reinforced PTFE (RPTFE) for low-friction operation and reliable sealing, even with particulate matter in seawater.
- Versatile End Connections: Available with flanged, threaded, or welded ends to seamlessly integrate into existing seawater cooling pipelines.
- Multiple Actuation Options: Can be supplied with a manual lever, gear operator for larger sizes, or automated with pneumatic actuators for remote control integration.
- Fire-Safe Design Option: An optional fire-safe design is available, where the valve maintains sealing integrity in case of exposure to high temperatures, a critical safety feature for marine applications.
- Full Bore Design: Standard full-port design minimizes pressure drop across the valve, ensuring efficient flow rates for cooling system performance.

Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for raw, unfiltered seawater?
A1: Yes, it is specifically designed for seawater service. The stainless steel construction resists biofouling and corrosion, and the sealing materials can handle typical particulates. For water with very high sediment, specifying a metal seat option is recommended.
Q2: What is the main difference between the CB/T3191 standard and other valve standards?
A2: The CB/T3191 is a Chinese national standard specifically developed for valves used on ships and marine platforms. It includes requirements for materials, pressure testing, and design that account for the unique challenges of the marine environment, such as vibration, salinity, and temperature fluctuations.
Q3: Can this valve be used for other fluids besides seawater?
A3: While optimized for seawater, its stainless steel construction makes it suitable for a range of other corrosive media in marine and industrial settings, such as certain chemicals, oils, or fresh water. Please consult with us for your specific fluid compatibility needs.
Q4: What actuation methods are available?
A4: We offer manual operation via a lever or gearbox (for larger diameters). For automated control, the valve can be fitted with pneumatic actuators. Electric actuators may also be available upon request.
Q5: Do you provide customization for specific project requirements?
A5: Absolutely. We can customize parameters such as pressure rating, end connection standards (e.g., ANSI, JIS), stem extension lengths for insulated lines, and special coatings or markings as required by your project specifications.
Q6: What is the typical lead time for an order?
A6: Lead time depends on the order quantity and specifications. Standard configurations are typically available from stock or have shorter production cycles. We provide clear lead time estimates with every quotation to help with your project planning.
Q7: What kind of testing is performed on these valves before shipment?
A7: Each valve undergoes rigorous testing, which usually includes a shell test (body pressure test), a seat leakage test, and an operational test to ensure smooth 90-degree rotation. Certificates of compliance and test reports can be provided.
Q8: How does your company ensure quality control?
A8: Our ISO9001 certified quality management system governs every stage, from raw material inspection and precision machining to final assembly and testing. This systematic approach guarantees that every valve meets our stringent standards and your expectations.
