As a dedicated manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd specializes in producing high-performance valves for demanding marine applications. Our DN50-DN200 Marine Gate Valve is engineered specifically for ship fuel oil systems, offering reliable flow control and shut-off in critical onboard pipelines. With an annual export value ranging between US$1 Million and US$1.5 Million, we have built a strong reputation for supplying durable and dependable valves to global markets including North America, South America, Eastern Europe, Southeast Asia, Africa, and beyond. This valve represents our commitment to quality, manufactured under an ISO9001 certified process to ensure consistent performance and longevity in marine environments.
This gate valve is designed to meet the rigorous requirements of marine fuel oil systems. Its robust carbon steel body provides excellent resistance to corrosion and mechanical stress, essential for handling various fuel oils. The valve features a full bore design to minimize flow resistance and pressure drop, ensuring efficient fuel transfer. The non-rising stem mechanism is particularly advantageous in confined ship spaces, as the handwheel position remains constant regardless of the valve's open or closed state. A metal-to-metal seal offers superior durability and leak prevention compared to soft seals, which can degrade over time with fuel exposure.
Key Advantages for Your Operations:
- Enhanced System Reliability: Provides a positive shut-off, crucial for maintenance, safety, and system isolation procedures on board.
- Long Service Life: The carbon steel construction and metal sealing are resistant to the chemical composition of marine fuels, reducing maintenance frequency.
- Space-Efficient Design: The non-rising stem design is ideal for installations with limited vertical clearance, a common challenge in ship engine rooms and piping manifolds.
- Easy Operation and Maintenance: Standard flanged connections facilitate installation and integration into existing systems. The manual handwheel operation is straightforward and does not require complex external power sources.

The valve's design prioritizes functionality in fuel service. The internal components are selected to withstand the specific properties of marine fuels, which may include viscosity variations and potential contaminants. The gate and seat are precision-machined to ensure a tight seal when closed, preventing leaks that could lead to safety hazards or operational inefficiencies. For installations requiring specific flange standards (such ASME, DIN, JIS), dimensions can be customized upon request to ensure compatibility with your existing piping.
Frequently Asked Questions (FAQ)
-
Is this valve suitable for high-pressure fuel oil lines?
This valve is designed for standard industrial pressure ratings common in ship fuel oil transfer and service systems. For specific high-pressure applications, please consult our technical team for a customized solution. -
Can the valve be operated remotely or automated?
The standard version is manual. However, adaptations for actuator mounting (electric, pneumatic) are available as an optional feature to suit automated control systems. -
What types of fuel oil is this valve compatible with?
It is compatible with common marine fuels such as Marine Diesel Oil (MDO), Heavy Fuel Oil (HFO), and similar petroleum-based fuels. Material selection ensures resistance to their chemical properties. -
How does the non-rising stem benefit marine installation?
It saves vertical space, as the handwheel does not move upward when opening. This is critical in tight engine rooms where overhead clearance is limited. -
Are spare parts like gaskets or seals readily available?
Yes. As a manufacturer, we maintain stock of critical spare parts and can supply them alongside the valve or separately to support your maintenance needs. -
What is the typical lead time for orders?
Lead times vary based on order quantity and specific customization. Standard sizes in our DN50-DN200 range often have shorter production cycles. We ship from major ports including Shanghai, Guangzhou, Hongkong, and Beijing. -
Does the valve come with any specific certifications for marine use?
The valve is manufactured under an ISO9001 certified quality system, ensuring consistent production control. Specific marine society approvals can be discussed based on project requirements. -
Can I request valves with different end connections besides flanged?
Yes. While flanged is standard, other connection types like welded ends can be provided as a customizable option to match your piping design.
