As a professional manufacturer with ISO9001 certification and extensive experience in marine valve production, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our CCS, DNV, and LR approved marine ball valves. Engineered specifically for demanding shipbuilding and FPSO applications, these valves represent the culmination of precision engineering, rigorous testing, and a deep understanding of maritime operational requirements. Our commitment to quality is reflected in our annual export value of US$1-1.5 million, serving global markets from North America to Southeast Asia. We understand that reliability at sea is non-negotiable, which is why our marine ball valves are designed to withstand harsh marine environments while ensuring smooth operation and long service life.
Core Product Features and Technical Advantages:
- Full Compliance with Marine Standards: Each valve undergoes stringent testing and inspection to meet the specific requirements of classification societies including CCS (China Classification Society), DNV (Det Norske Veritas), and LR (Lloyd's Register). This ensures global acceptance and compliance with international maritime regulations.
- Robust Construction for Harsh Environments: Manufactured from marine-grade materials selected for their corrosion resistance and mechanical strength. Common material combinations include carbon steel with appropriate coatings, 316 stainless steel, and duplex steels for highly corrosive services.
- Superior Sealing Performance: Features advanced seat designs with materials like PTFE or reinforced PTFE that provide bubble-tight sealing even after prolonged cycling. Metal-seated versions are available for high-temperature or abrasive service conditions.
- Versatile Operation Options: Available with manual operation (lever or gear), pneumatic actuation, or electric actuation to suit various control system requirements on vessels and offshore installations.
- Fire-Safe Design Available: Optional fire-safe construction compliant with API 607/API 6FA standards, providing critical protection in emergency situations where valve integrity during fire exposure is essential.
- Low Maintenance Design: Engineered for easy maintenance with extended service intervals, reducing downtime and operational costs for vessel operators.

Application-Specific Benefits:
- For Shipbuilding: These valves are integral to various ship systems including ballast, bilge, fuel oil, lubricating oil, cooling water, compressed air, and firefighting systems. Their reliable performance contributes to vessel safety and operational efficiency.
- For FPSO Applications: Designed to handle the challenging conditions of floating production, storage, and offloading units, including crude oil processing, seawater injection, produced water, and utility systems. The valves' robust construction resists vibration and corrosive marine atmospheres.
- For Offshore Platforms: Suitable for seawater lift, cooling systems, chemical injection, and utility services on fixed and floating platforms where reliability and maintenance accessibility are critical factors.
- For Marine Terminals: Used in loading arms, manifold systems, and transfer lines where quick operation and positive shut-off are required for safe cargo handling operations.
Manufacturing and Quality Assurance: Our manufacturing process incorporates advanced CNC machining centers, automated welding where applicable, and comprehensive testing facilities. Every valve undergoes pressure testing, shell testing, and seat testing according to relevant standards before receiving final inspection and certification documentation. The ISO9001 certified quality management system ensures consistent product quality and traceability.
With established operations since 2016 and a proven track record of exporting to diverse markets including North America, South America, Europe, Asia, Africa, and Oceania, Shanghai Zhibang has built a reputation for delivering reliable marine valves. Our strategic location with multiple shipment ports (Shanghai, Guangzhou, Hong Kong, Beijing) ensures efficient logistics and timely delivery to global customers.

Frequently Asked Questions (FAQ):
Q: What documentation comes with your DNV/LR approved marine ball valves?
A: Each valve is supplied with a comprehensive documentation package that typically includes material certificates, pressure test reports, final inspection report, and the relevant classification society approval certificate (DNV, LR, CCS, etc.). Certificates of origin and compliance may also be provided upon request.
Q: Can you provide valves with approvals from other classification societies besides CCS, DNV, and LR?
A: Yes. While CCS, DNV, and LR are among our most common approvals, we can manufacture valves to meet the requirements of other major classification societies including ABS, BV, GL, KR, RINA, and others. Specific requirements should be discussed during the inquiry stage.
Q: What is the typical delivery time for these marine ball valves?
A: Delivery time varies based on size, material, pressure rating, and approval requirements. Standard configurations typically have shorter lead times, while specialized materials or additional certifications may require more time. We provide estimated delivery schedules with each quotation.
Q: Are your marine ball valves suitable for cryogenic service on LNG carriers?
A: We offer specially designed ball valves for cryogenic applications, including LNG service. These valves feature extended bonnets, special low-temperature materials, and appropriate seat designs. Specific requirements for LNG applications should be detailed in your inquiry.
Q: Do you offer actuated versions of these marine ball valves?
A: Yes. We can supply valves with pneumatic, electric, or hydraulic actuators from reputable manufacturers. Actuators can be sized and selected based on your specific system requirements, including fail-safe modes and control signals.
Q: What maintenance is required for these valves in marine service?
A: Our marine ball valves are designed for minimal maintenance. Periodic lubrication of the stem (if applicable) and operational checks are typically sufficient. Seat and seal replacement kits are available for extended service life. Detailed maintenance instructions are provided with each valve.
Q: Can you provide custom designs or modifications for specific project requirements?
A: We have engineering capability to modify standard designs to meet specific project requirements, including special dimensions, connections, materials, or operational features. Engineering consultation is available to discuss custom solutions.
Q: What is your warranty policy for marine ball valves?
A: We provide a standard warranty against defects in materials and workmanship. The specific terms and duration may vary based on the application and service conditions. Warranty details are provided with our commercial terms.
