As a professional manufacturer with a strong focus on marine fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our GB/T Marine Gate Valve designed specifically for fuel oil service. Engineered with precision and durability in mind, this valve is a critical component for ensuring safe, reliable, and efficient fuel transfer and isolation on board vessels. With our commitment to quality underscored by ISO9001 certification and years of experience since 2016, we deliver valves that meet the rigorous demands of the global maritime industry.
Our gate valves are constructed to provide a tight seal and full, unobstructed flow when open, making them ideal for on/off service in fuel oil lines. The robust carbon steel body offers excellent strength and corrosion resistance necessary for the challenging marine environment. We understand that downtime is costly at sea, which is why reliability is at the core of our design philosophy.
- Robust Construction: The carbon steel body and internal components are selected for their mechanical strength and compatibility with marine fuel oils, ensuring long service life even under constant vibration and pressure fluctuations.
- Precise Sealing: Features a metal-to-metal seated design that provides a bubble-tight shut-off, preventing fuel leakage and ensuring operational safety and environmental protection.
- Standard Compliance: Manufactured in strict accordance with GB/T (Chinese National Standard) specifications, which are widely recognized and accepted in international marine projects, particularly in our key markets across Asia, Europe, and the Americas.
- Easy Operation & Maintenance: The outside screw and yoke (OS&Y) design with a rising stem provides clear visual indication of the valve position (open or closed). The handwheel operation is designed for ergonomic use, and the packing gland is easily accessible for maintenance.
- Versatile Sizing: Available in a comprehensive range from DN50 to DN200, allowing for seamless integration into various pipeline diameters within a ship's fuel oil system, from bunkering lines to service lines to engines.
- Flanged Connection: Standard flanged ends per relevant standards facilitate secure and leak-free bolting to pipeline flanges, simplifying installation and replacement procedures.

Frequently Asked Questions (FAQ)
Q1: Is this valve suitable for other fluids besides fuel oil?
A1: While specifically designed for fuel oil service, this carbon steel gate valve can potentially handle other non-corrosive, moderate-temperature liquids such as lube oil or water. However, compatibility should be verified based on the specific fluid's properties. For aggressive chemicals or high-purity applications, alternative materials may be recommended.
Q2: What does "GB/T" standard mean, and is it accepted internationally?
A2: GB/T stands for "Guobiao/Tuijian," which are Chinese National Recommended Standards. They are well-established and widely accepted in many international markets, particularly in shipbuilding and industrial projects across Asia, Africa, and the Middle East. Many specifications align with common international practices.
Q3: Can you provide valves with different pressure ratings, like PN2.5MPa or PN4.0MPa?
A3: Yes, customization is available. While PN1.6MPa is a common rating for many fuel oil services, we can manufacture valves to other pressure classes (PN2.5, PN4.0, etc.) upon request. Please provide your specific pressure requirement during inquiry.
Q4: What is the lead time for an order of DN150 valves?
A4: Lead times vary based on order quantity and current production schedule. Generally, for standard sizes like DN150, we can often arrange shipment within a few weeks. We provide estimated lead times with every formal quotation and leverage our multiple port shipment options (Shanghai, Guangzhou, etc.) to optimize delivery.
Q5: Do you offer any actuation options besides the manual handwheel?
A5: Absolutely. We can equip these gate valves with electric actuators, pneumatic actuators, or gear operators to suit remote or automated control needs. This is a customizable feature; please specify your actuation requirements when you contact us.
Q6: How do I determine the correct flange standard for my existing piping?
A6: We typically manufacture flanges according to common international standards. To ensure compatibility, please provide the flange standard you require (e.g., ANSI, JIS, DIN) along with the pressure class and facing details. Our technical team can advise based on your system specifications.
Q7: What kind of testing do these valves undergo before shipment?
A7: Each valve undergoes standard factory tests, which typically include a shell test (body strength) and a seat test (sealing performance) using water or air as per standard procedures. Detailed test reports can be provided upon request.
Q8: Are spare parts like gland packing or gaskets readily available?
A8: Yes. We maintain an inventory of common spare parts and can supply them with the initial order or separately. Using genuine spare parts ensures optimal performance and longevity of the valve.
