As a professional manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine ball valves that meet the rigorous demands of global maritime operations. Established in 2016, our focus is on delivering durable and efficient fluid control solutions. Our CB/T3191 Marine Ball Valves, crafted from premium 316 stainless steel, are engineered to withstand corrosive marine environments, ensuring long-lasting service and minimal maintenance for your critical systems.
Our valves are designed to provide superior sealing performance and reliable operation under high pressure and variable temperature conditions commonly found in shipboard applications. We understand that downtime is costly, which is why our products are built for endurance and ease of operation. With an annual export value reflecting our global reach and customer trust, we supply valves to markets worldwide, including North America, Europe, Southeast Asia, and Africa, supporting a diverse range of marine projects.
Core Product Features & Technical Advantages:
- Corrosion-Resistant Construction: The valve body, ball, and stem are manufactured from 316 stainless steel, offering exceptional resistance to pitting and crevice corrosion in saltwater and chloride-rich environments, significantly extending the valve's service life.
- Wide Size and Pressure Compatibility: Available in a comprehensive range from DN15 to DN300, these valves cater to various pipeline diameters. They are designed for pressure ratings typically from PN16 to PN40, with options for higher ratings available upon request to suit specific system requirements.
- Robust Sealing Mechanism: Equipped with advanced seat materials like PTFE or reinforced PTFE, the valves ensure bubble-tight shut-off, preventing leaks and ensuring system integrity. Metal-seated options are available for high-temperature or abrasive service.
- Versatile End Connections: To facilitate easy integration into existing piping systems, the valves are offered with flanged, threaded, or butt-weld end connections, providing flexibility for installation and maintenance.
- Multiple Actuation Options: While supplied with a standard manual lever for quick operation, these valves can be easily fitted with gear operators for high-torque applications or automated with pneumatic/electric actuators for remote control and integration into automated systems.
- Compliance with Marine Standards: Manufactured in accordance with the CB/T3191 standard, these valves are suitable for marine and offshore applications, ensuring they meet specific industry guidelines for design and performance.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of using 316 stainless steel for marine ball valves?
A: 316 stainless steel contains molybdenum, which greatly enhances its resistance to corrosion from chlorides and saltwater, making it a preferred material for harsh marine environments compared to standard 304 stainless steel. -
Q: Can these valves be used for both on/off service and flow control?
A: Primarily designed for reliable on/off isolation, these ball valves can be used for moderate throttling in certain applications. However, for precise flow control, we recommend consulting our engineers for the most suitable valve trim. -
Q: Do you provide documentation with the valves?
A: Yes, a crucial part of our delivery is the Mill Test Report (MTR) for material traceability. Other documentation like certificates of conformance, packing lists, and installation manuals are also provided. -
Q: Are the valves suitable for high-temperature applications on ships, like steam lines?
A: With standard PTFE seats, the temperature range is limited. For steam or higher temperature services, we offer valves with metal-seated or high-performance polymer seats. Please specify your operating temperature during inquiry. -
Q: What is the lead time for an order of DN200 valves?
A: Lead times vary based on order quantity and specific configuration. Standard DN200 valves are often in stock or have shorter production cycles. We provide accurate lead time estimates upon receipt of your official inquiry. -
Q: Can you supply valves with actuators for automated systems?
A: Absolutely. We can assemble and test the valves with pneumatic (double-acting or spring-return) or electric actuators from reputable brands, providing a ready-to-install automated valve package. -
Q: What does "OEM Factory" mean in your context?
A: It means we are the original manufacturer. We can produce valves according to your drawings, specifications, or private label them with your company's branding, offering a complete OEM/ODM service. -
Q: How do you ensure quality control during manufacturing?
A> Our ISO9001-certified quality management system mandates strict controls at every stage, including incoming material checks, in-process inspections, and final hydrostatic and pneumatic shell/seat tests before shipment.
