As a professional valve manufacturer with ISO9001-certified quality management, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our CB/T3591-2005 Marine Standard Ductile Iron Gate Valve. Engineered for demanding marine applications, this PN16-rated, flanged-end valve combines robust construction with reliable performance, ensuring safe and efficient fluid control in critical shipboard systems. Since our establishment in 2016, we have focused on delivering durable industrial valves that meet stringent international standards, and this product exemplifies our commitment to quality and customer satisfaction in markets across the globe.
Our CB/T3591-2005 Marine Gate Valve is designed to provide secure isolation in pipelines. Its primary features and advantages include:
- Marine-Specific Design: Manufactured in strict compliance with the CB/T3591-2005 Chinese marine standard, ensuring suitability for shipbuilding and offshore platform applications.
- Superior Material: The valve body and bonnet are crafted from high-grade ductile iron, offering excellent strength, impact resistance, and corrosion resistance, which is vital for the harsh marine environment.
- Reliable Sealing: Features a robust gate and seat design. The sealing components can be customized with materials like EPDM or NBR to ensure a tight shut-off and compatibility with various media, including seawater, oil, and air.
- Durable Operation: Equipped with a rising stem and Outside Screw & Yoke (OS&Y) design. The stem is typically made of stainless steel, providing smooth operation, clear visual indication of valve position, and protection of the threaded parts from the fluid.
- Easy Installation & Maintenance: The flanged ends conform to standard dimensions (e.g., ISO, DIN, ANSI), facilitating easy connection to existing pipeline systems and simplifying installation and future maintenance.
- Enhanced Protection: A high-quality epoxy coating is applied externally to provide an additional layer of protection against corrosion, extending the valve's service life.

Frequently Asked Questions (FAQ):
-
Q: What does the "CB/T3591-2005" standard signify?
A: This is a Chinese national standard specifically for marine valves. It defines the technical requirements, materials, testing methods, and inspection rules for gate valves used in shipbuilding and marine engineering, ensuring they meet the safety and performance demands of marine environments. -
Q: Can this valve be used for applications other than marine?
A: Yes, absolutely. While designed to marine standards, its robust PN16 rating and ductile iron construction make it suitable for various industrial applications involving water, oil, gas, and other neutral fluids in power plants, water treatment, and general piping systems. -
Q: What flange standards are compatible?
A: The flanged ends are manufactured to common international standards. Specific standards (such as DIN, ANSI, JIS) and facing details (RF, FF) can be specified upon order to match your existing pipeline connections. -
Q: Is the valve suitable for seawater service?
A: Yes, with the appropriate material selection. The ductile iron body with epoxy coating offers good corrosion resistance. For optimal long-term performance in direct seawater contact, specifying suitable stainless steel trim and seawater-compatible seat materials (like EPDM) is recommended. -
Q: What is the available size range?
A: The valve is typically available in a range of nominal diameters (DN). Common sizes from DN50 to DN300 are often stocked or readily producible. Please inquire for specific size requirements and lead times. -
Q: Do you offer actuated versions of this valve?
A: Yes, we can provide customization. The standard handwheel-operated valve can be fitted with electric, pneumatic, or hydraulic actuators upon request to enable remote or automated control. -
Q: What is the lead time for orders?
A: Lead time depends on order quantity, specific size, and customization requirements. Standard configurations may have shorter lead times. We strive to provide accurate timelines upon receipt of your detailed inquiry. -
Q: What are the packaging and shipping terms?
A: Valves are securely packaged in wooden cases for export protection. We ship from multiple ports including Shanghai, Guangzhou, and Hong Kong. Shipping terms (FOB, CIF, etc.) can be negotiated based on your destination and preferences.
