As a leading manufacturer with a strong commitment to maritime and offshore industries, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our specialized CB/T3191 Bronze Marine Ball Valve with Locking Handle. Engineered for the demanding environments of secure offshore operations, this valve represents a fusion of robust construction, reliable performance, and essential safety features. Since our establishment in 2016, we have focused on delivering high-quality fluid control solutions, with our products reaching key markets across North America, South America, Europe, Asia, and beyond. This particular valve is designed to address the critical need for secure, tamper-proof flow control in marine applications, ensuring operational integrity and safety on vessels and offshore platforms.
Our valve is meticulously crafted to meet the stringent requirements of marine service. The primary body and components are constructed from high-grade bronze alloy, offering excellent corrosion resistance against seawater, brackish water, and harsh atmospheric conditions typical of offshore environments. This material choice ensures long-term durability and minimizes maintenance needs.
Core Features and Technical Advantages:
- Integrated Locking Handle for Security: The standout feature is the built-in locking handle mechanism. This allows the valve to be secured in either the fully open or fully closed position using a padlock (typically not included). This is crucial for offshore safety protocols, preventing unauthorized or accidental operation that could lead to process upsets, spills, or safety hazards.
- Robust Construction for Marine Duty: Manufactured in compliance with the Chinese CB/T3191 standard for marine valves, it ensures compatibility and reliability for shipbuilding and repair. The design prioritizes strength and leak-tight performance under variable pressures and temperatures.
- Superior Sealing Performance: Equipped with seats made from PTFE (Polytetrafluoroethylene) or reinforced PTFE, providing a bubble-tight seal, low operating torque, and excellent chemical resistance to various marine fluids, including fuels, lubricants, and water.
- Quarter-Turn, Easy Operation: The ball valve design allows for quick and easy on/off control with a simple 90-degree turn of the lever handle, facilitating efficient operation even in tight or difficult-to-access spaces onboard.
- Versatile Connection Options: Available with various end connections to suit different piping systems, including threaded (NPT, BSP) and flanged ends, ensuring easy integration into existing marine infrastructure.

Frequently Asked Questions (FAQ):
Q1: What is the main purpose of the locking handle on this ball valve?
A1: The primary purpose is safety and security. It allows the valve to be physically locked in the open or closed position using a padlock. This is essential for implementing lock-out/tag-out (LOTO) procedures, preventing unauthorized operation, and ensuring a fluid system remains in a known, safe state during maintenance or in critical offshore processes.
Q2: Is this valve suitable for use with seawater?
A2: Yes, it is specifically designed for marine environments. The bronze body material offers excellent resistance to corrosion from seawater and salt-laden atmospheres. The seat materials (PTFE) are also chemically inert and resistant to marine fluids.
Q3: What standards does this valve conform to?
A3: This valve is manufactured according to the Chinese CB/T3191 standard, which is a standard for marine valves. It may also conform to other general standards like GB/T. Specific certifications like ISO 17292 for petroleum and natural gas industries can be confirmed upon request.
Q4: What pressure classes are available?
A4: Common pressure ratings include PN16 and PN25 (metric) or Class 150 and Class 300 (ASME). The available pressure class depends on the valve size and specific model. Please consult with us for the exact specifications for your required size.
Q5: Can I get this valve with different end connections?
A5: Absolutely. We offer versatility in end connections to match your piping system. Standard options include threaded ends (NPT or BSP) and flanged ends. Other connection types may be available as a customization option.
Q6: What is the temperature range for operation?
A6: The standard valve is designed for a temperature range of approximately -20°C to 200°C (-4°F to 392°F), making it suitable for most marine fluid services, from chilled water to hot water and various oils.
Q7: Do you provide the padlock for the locking handle?
A7: Typically, the padlock is not included with the valve, as customers often have specific requirements or existing lockout hardware. The handle is designed with a standard shackle hole to accommodate commonly available padlocks.
Q8: What is your shipping and delivery capability?
A8: As an experienced exporter, we ship worldwide from major Chinese ports including Shanghai, Guangzhou, and Hong Kong. We have extensive experience supplying to markets in the Americas, Europe, Asia, Africa, and Oceania, and can arrange suitable logistics for your order.
