As a leading manufacturer with a strong commitment to quality and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our JIS F7301 Marine Ball Valve, engineered specifically for demanding fuel oil systems onboard vessels. With our ISO9001-certified production processes and a focus on the global maritime industry, we understand the critical need for valves that ensure safety, prevent leaks, and withstand harsh marine environments. This carbon steel ball valve with PTFE seals represents our dedication to providing robust and dependable flow control solutions that shipbuilders and operators can trust for seamless and secure operations.
Designed to meet the rigorous JIS F7301 standard for marine valves, this product is built for longevity and performance in fuel oil transfer, bunkering, and internal ship piping systems. Its construction and features directly address the common challenges in maritime applications, such as corrosion, pressure surges, and the need for frequent operation.
- Superior Sealing and Durability: The valve incorporates high-quality PTFE (Polytetrafluoroethylene) seats and seals. This material offers exceptional chemical resistance to fuel oils, excellent low-friction operation, and reliable sealing across a wide temperature range from -20°C to 180°C, ensuring leak-tight shut-off and extended service life.
- Robust Carbon Steel Construction: The body and major components are made from forged or cast carbon steel, providing high mechanical strength and pressure integrity. The material is suitable for the pressures and mechanical stresses encountered in marine fuel systems.
- Versatile Design and Configuration: Available in sizes from DN15 to DN50, the valve supports various connection types and operation methods to fit specific system layouts and automation needs.
- Corrosion Resistance: While carbon steel offers strength, appropriate surface treatments or coatings are available upon request to enhance corrosion resistance against saltwater atmospheres and splashes.
- Easy Operation and Maintenance: The quarter-turn operation allows for quick open/close functions. The stem sealing system is designed for easy adjustment or repacking, minimizing downtime during maintenance.

Frequently Asked Questions (FAQ)
-
Q: Is this valve suitable for heavy fuel oil (HFO) as well as marine diesel oil (MDO)?
A: Yes, the PTFE sealing material offers excellent resistance to both types of marine fuels, making the valve suitable for various fuel oil services within its pressure and temperature ratings. -
Q: What are the available end connections for the DN15-DN50 size range?
A: We offer threaded connections (NPT, BSP) for smaller sizes and flanged connections (JIS 10K/20K, ANSI 150/300) as standard options. Custom end preparations can be discussed based on your piping specifications. -
Q: Can this valve be supplied with an actuator for remote operation?
A: Absolutely. The valve can be configured with pneumatic, hydraulic, or electric actuators. Please provide your required operation specifications (e.g., fail-safe mode, control signal) for a tailored solution. -
Q: Does the valve have a fire-safe design?
A: A fire-safe design, which includes secondary metal sealing in case the primary PTFE seal is compromised by fire, is available as an optional feature. Please specify this requirement when inquiring. -
Q: What surface treatment is applied to the carbon steel body for marine use?
A: Standard valves receive a protective coating or paint. For enhanced corrosion resistance in severe marine atmospheres, options like epoxy coatings or galvanizing can be provided upon request. -
Q: Are spare parts like seals and gaskets readily available?
A: Yes, as the manufacturer, we maintain an inventory of critical spare parts. We recommend keeping a set of maintenance kits for essential components to ensure quick turnaround during scheduled upkeep. -
Q: What documentation is provided with the valve?
A: Standard documentation includes a material test certificate, dimensional drawing, and a manual. Additional certificates, such as a pressure test report or third-party inspection reports, can be arranged. -
Q: What is the typical lead time for an order of these valves?
A: Lead time depends on the order quantity, specific configuration, and actuator requirements. For standard manual valves in common sizes, we often have stock or short production cycles. We provide a clear timeline upon receipt of your detailed inquiry.
