As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our High Temperature Marine Ball Valve series. Engineered specifically for demanding marine and offshore applications, this valve is designed to deliver exceptional performance, durability, and safety under extreme conditions. Our valves are manufactured in strict compliance with the CB/T3191 standard, ensuring they meet the rigorous requirements of the shipbuilding industry. With years of experience since our establishment in 2016 and a proven export track record, we provide robust fluid control solutions trusted by clients across the globe from North America to Southeast Asia.

Our High Temperature Marine Ball Valve is a cornerstone for critical piping systems onboard vessels and offshore installations. Its core value lies in providing a reliable shut-off solution that withstands high temperatures, corrosive seawater environments, and constant vibration, contributing to the overall operational safety and efficiency of marine assets.

Key Features & Technical Advantages:

Superior High-Temperature Performance: Specially designed seat and seal materials allow reliable operation at elevated temperatures, making it suitable for steam lines, hot water circuits, and other high-temperature fluid services on ships.
Robust Construction for Marine Use: The valve body is constructed from premium-grade materials such as carbon steel (WCB), stainless steel (CF8/CF8M), or duplex steel, offering excellent resistance to seawater corrosion and mechanical stress.
CB/T3191 Standard Compliance: Full adherence to this Chinese ship standard guarantees the valve's design, materials, manufacturing, testing, and marking are suitable for marine applications, providing peace of mind for shipyards and ship owners.
Flanged End Connection: The flanged ends (DN15 to DN100) ensure a secure, leak-proof connection to the pipeline, facilitating easy installation, maintenance, and replacement, which is crucial in space-constrained engine rooms.
Fire-Safe Design Option: Available with fire-safe features according to API 607/API 6FA standards, where the valve maintains sealing integrity even under fire conditions, enhancing onboard safety.
Versatile Actuation Options: Can be operated manually via a lever or gearbox, or automated with pneumatic or electric actuators for remote control and integration into ship automation systems.
Low Maintenance & Long Service Life: The streamlined ball design minimizes pressure drop and the self-lubricating seats reduce wear, leading to lower lifecycle costs and less downtime for maintenance.

Frequently Asked Questions (FAQ)

Q: What exactly does "CB/T3191 Standard" mean for this ball valve?
A: CB/T3191 is a Chinese professional standard for marine valves. Compliance means the valve's design, material selection, manufacturing process, testing methods, and marking are specifically approved for use in marine and offshore applications, ensuring it meets the safety and performance demands of ship classification societies.
Q: Can this valve handle both high temperatures and seawater corrosion?
A> Yes, absolutely. By selecting appropriate body materials like stainless steel or duplex steel and high-performance seat materials (e.g., metal seats or specialized polymers like PEEK), the valve is engineered to resist corrosion from seawater while maintaining its sealing integrity at elevated temperatures common in engine room systems.
Q: What are the available flange standards and face types?
A> We typically supply flanges according to international standards like DIN, ANSI, JIS, or GB (Chinese national standard). Common face types include Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ). Please specify your required standard and face type when inquiring.
Q: Is the valve suitable for fire-safe applications?
A> A fire-safe design is available as an option. These valves incorporate features such as secondary metal seals that engage in case the primary soft seal is damaged by fire, helping to prevent catastrophic fluid release. Relevant certifications like API 607 can be provided upon request.
Q: Do you offer automated actuation for these valves?
A> Yes. While standard valves come with a manual lever, we can equip them with pneumatic (on/off or modulating) or electric actuators. This allows for integration into the ship's centralized control system for remote operation, which is highly valued in modern vessel design.
Q: What is the typical lead time for an order?
A> Lead time depends on order quantity, material specification, and actuation requirements. For standard configurations, we often have stock or can deliver within 15-30 days. Customized orders may require 30-45 days. We provide accurate timelines upon receipt of your detailed inquiry.
Q: What kind of testing do your valves undergo before shipment?
A> Each valve undergoes a comprehensive testing protocol, which includes hydrostatic shell testing (at 1.5 times rated pressure), seat leakage testing, and operational cycling tests. Test reports can be supplied with the shipment. Additional tests like NDE (Non-Destructive Examination) are available.
Q: Can you provide valves in sizes outside the DN15-DN100 range?
A> Our standard production focuses on the DN15 to DN100 range. However, we have the capability to manufacture larger or smaller sizes based on customer demand. Please contact our engineering team to discuss your specific size requirements.
