As a specialized manufacturer with a focus on the marine industry, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance OEM Marine Ball Valves engineered in strict compliance with the CB/T3191 standard. With extensive experience since our establishment in 2016, we understand the critical demands of shipboard piping systems for reliability, durability, and safety. This valve is designed to offer superior sealing performance and robust construction, making it an ideal choice for controlling the flow of seawater, fuel, lubricating oil, and compressed air on vessels. We offer complete customization for actuator types and flange standards to ensure seamless integration into your specific marine application, providing a perfect balance of standard compliance and tailored functionality.
Our Marine Ball Valve is built to withstand the harsh conditions of the maritime environment. Key features and technical specifications include:
- Robust Construction & Materials: The valve body is typically manufactured from high-grade cast steel, stainless steel (CF8, CF8M, CF3, CF3M), or bronze, selected for excellent corrosion resistance against seawater and marine atmospheres. The ball is often chrome-plated or made from stainless steel for a smooth, durable sealing surface.
- Superior Sealing System: Utilizes advanced seat materials like PTFE (Polytetrafluoroethylene) or reinforced PTFE, which provide a bubble-tight seal, low operating torque, and excellent chemical resistance. Metal-seated versions are available for high-temperature applications.
-
Customizable Actuation: We provide flexible actuation solutions to meet diverse operational needs. Valves can be supplied as standard manual operation (lever or gearbox) or customized with:
- Electric Actuators: For remote control and automation integration.
- Pneumatic Actuators: For quick on/off action using shipboard compressed air.
- Hydraulic Actuators: For high-torque requirements in critical systems.
-
Flange Standard Flexibility: Understanding the global nature of shipbuilding and repair, we customize flange connections to match your project specifications. Common standards we accommodate include:
Flange Standard Typical Application Regions JIS (Japanese Industrial Standard) Ships built in or for East Asian markets ANSI (American National Standards Institute) Vessels for North/South American markets DIN (Deutsches Institut für Normung) European shipbuilding and repair yards GB (Chinese National Standard) Domestic Chinese shipbuilding projects - CB/T3191 Compliance: This Chinese ship standard ensures the valve design, materials, testing, and marking meet specific requirements for marine use, covering aspects like pressure-temperature ratings, fire-safe design (if applicable), and structural integrity for vibration and shock.

Frequently Asked Questions (FAQ)
-
Q: What does CB/T3191 standard mean for this ball valve?
A: CB/T3191 is a Chinese national standard specifically for marine valves. Compliance ensures the valve's design, material selection, pressure-temperature ratings, testing methods (like shell test, seat test), and marking are suitable for the demanding conditions of shipboard service, including considerations for vibration and potential shock loads. -
Q: Can you provide valves with actuators other than manual levers?
A: Yes, absolutely. A core service we offer is actuator customization. We can equip the ball valve with electric actuators (for automated control systems), pneumatic actuators (for use with shipboard air supply), or hydraulic actuators, depending on your system's power source and control requirements. -
Q: My project requires JIS 10K flanges. Can you accommodate this?
A: Certainly. We specialize in customizing flange standards. Whether you need JIS, ANSI, DIN, GB, or other specifications, we can manufacture the valve with the corresponding flange dimensions, drilling patterns, and facing to match your existing piping seamlessly. -
Q: What materials are typically used for the body and seats in marine environments?
A: For corrosion resistance, common body materials are cast steel with appropriate coatings, stainless steel grades (like 304 or 316), or bronze. Seat materials are often PTFE or reinforced PTFE for excellent sealing and chemical resistance; metal seats (Stellite) are an option for higher temperature services. -
Q: Is this valve suitable for freshwater and seawater systems on a ship?
A: Yes, it is designed for various marine fluid services. The material selection is key. For seawater (which is highly corrosive), we would typically recommend stainless steel (316/316L) or properly coated carbon steel valves to ensure long service life. -
Q: Do you offer fire-safe design options?
A: Fire-safe design is a common requirement for certain marine applications (e.g., fuel lines). We can provide valves that meet recognized fire-safe testing standards (like API 607/API 6FA). Please specify this requirement during inquiry so we can configure the valve with appropriate secondary metal seals. -
Q: What is your typical lead time for a customized order?
A: Lead time depends on order quantity, material availability, and the complexity of customization (actuator type, flange standard). For standard CB/T3191 valves with common customizations, production typically ranges from 30 to 45 days. We provide a precise schedule upon order confirmation. -
Q: What quality control procedures do you have in place?
A: Our manufacturing process is governed by our ISO9001 quality system. Each valve undergoes rigorous inspections, including material certification checks, dimensional verification, pressure testing (shell and seat tests per standard requirements), and operational tests. Final inspection reports can be provided.
