As a leading manufacturer with a strong commitment to maritime safety and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CB/T590 Marine Globe Valve, supplied with a Full Material Mill Test Report (MTR). Established in 2016 and holding ISO9001 certification, we understand the critical demands of marine applications where every component's traceability and performance are non-negotiable. This valve is engineered to meet the rigorous CB/T590 standard, specifically designed for shipbuilding and offshore industries, ensuring dependable flow control under challenging sea conditions. We combine robust manufacturing with complete material documentation, providing you with not just a valve, but verifiable quality and peace of mind for your critical marine projects.
Our CB/T590 Marine Globe Valve stands out in the global market, trusted by clients across North America, South America, Europe, Asia, Africa, and Oceania. Its core value lies in the guaranteed material integrity backed by the supplied MTR, a crucial document for classification society approvals and routine vessel inspections. This feature directly addresses the stringent procurement requirements of shipyards, marine engineers, and system integrators worldwide.
Key Features & Technical Advantages:
- Full Material Traceability: Each valve is accompanied by a Mill Test Report detailing the chemical composition and mechanical properties of all primary pressure-containing parts (body, bonnet, stem, disc). This ensures compliance with material specifications and simplifies regulatory audits.
- Rugged Construction for Marine Duty: Designed to withstand vibration, shock, and corrosive seawater environments. The robust design ensures long-term, leak-free service in critical applications like bilge systems, ballast systems, cooling water lines, and fuel oil systems.
- Precise Flow Regulation: The globe valve design offers excellent throttling capability and positive shut-off, allowing for fine control over fluid flow rates, which is essential for many marine processes.
- Versatile Configuration Options: Available in a range of materials, pressure ratings, and actuation methods to suit specific system requirements and space constraints onboard.
- Global Compliance & Support: Shipped from major ports like Shanghai, Guangzhou, Hong Kong, and Beijing, we ensure timely delivery to support international projects and maintenance schedules.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the CB/T590 standard for marine valves?
A: CB/T590 is a Chinese national standard specifically developed for shipbuilding. Valves conforming to this standard are designed and tested to meet the unique demands of marine environments, including vibration resistance, corrosion protection, and specific pressure-temperature ratings for shipboard systems. -
Q: Why is the Full Material Mill Test Report (MTR) so important?
A: In marine and offshore industries, material traceability is critical for safety and compliance. The MTR provides verified data on the metal's grade, strength, and composition, which is required by classification societies (like ABS, DNV, LR) to approve the valve for use on vessels. It ensures the material meets the specified standard. -
Q: Can this valve be used with media other than water?
A: Yes. While commonly used for seawater, ballast, and cooling water, the valve's material selection (e.g., stainless steel or duplex steel) makes it suitable for a wider range of media, including oils, fuels, and certain chemicals. The specific compatibility depends on the selected body and trim materials. -
Q: Are these valves suitable for both new shipbuilding and retrofit projects?
A: Absolutely. They are ideal for new constructions requiring CB/T590 compliant components. For retrofit or repair projects, they serve as reliable, certified replacements for existing globe valves, especially when documentation for the original parts is missing. -
Q: What types of actuators can be fitted to this globe valve?
A> The valve can be supplied with a standard handwheel. For remote or automated operation, it can be fitted with pneumatic (on/off or modulating) or electric actuators. Gear operators are also available for high-torque applications. Actuator selection is customizable upon request. -
Q: How does your ISO9001 certification benefit the buyer?
A> Our ISO9001 certification demonstrates a consistent, controlled manufacturing process. This translates into reliable product quality, batch-to-batch consistency, and a systematic approach to meeting customer requirements and industry standards, providing an additional layer of confidence. -
Q: What is your typical lead time and shipping process?
A> Lead times vary based on specification and order quantity. We ship efficiently from ports in Shanghai, Guangzhou, Hong Kong, and Beijing, facilitating smooth logistics to our main markets worldwide, including the Americas, Europe, Asia, and Africa. -
Q: Do you offer custom modifications to the standard CB/T590 design?
A> Yes, we can discuss customizations such as special coatings, extended stems, specific locking devices, or modifications to meet unique project specifications. Please contact our sales team with your detailed requirements.
