As a dedicated manufacturer with a focus on precision and reliability, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our JIS F7300 Marine Ball Valve. Engineered for demanding marine and industrial applications, this full bore carbon steel valve is designed to deliver superior flow capacity and minimize system pressure drop. Since our establishment in 2016, we have committed to producing valves that meet rigorous international standards, backed by our ISO9001 certified quality management system. This valve is a testament to our expertise, offering a robust solution for clients in shipbuilding, offshore platforms, and process industries worldwide who require dependable performance and documented material traceability.
Our JIS F7300 Marine Ball Valve is constructed to provide optimal flow with minimal resistance. The full bore design ensures a smooth, unrestricted passage for fluids, which is critical for maintaining system efficiency and reducing pump energy consumption. Each valve is accompanied by a Mill Test Report (MTR), providing verifiable documentation of the chemical composition and mechanical properties of the carbon steel materials used, ensuring compliance with project specifications and quality assurance protocols.
Key Features & Technical Advantages:
- Full Bore Design: The valve's internal diameter matches the pipeline, offering a straight-through flow path that significantly lowers pressure loss and prevents turbulence.
- Robust Carbon Steel Construction: Manufactured from high-grade carbon steel, the valve exhibits excellent strength, durability, and resistance to corrosion in marine environments.
- JIS F7300 Compliance: Manufactured in strict adherence to the Japanese Industrial Standard for marine valves, ensuring reliability and interchangeability in marine applications.
- Versatile End Connections: Available in various configurations including threaded (NPT, BSP), flanged (JIS, ANSI, DIN), and socket weld to suit different piping system requirements.
- Superior Sealing Performance: Utilizes advanced seat materials such as PTFE or reinforced PTFE for tight shut-off and reliable service across a wide temperature range. Metal-seated options are available for high-temperature or abrasive service.
- Low Torque Operation: The precision-machined ball and stem assembly allows for easy quarter-turn operation, even under high differential pressure.
- Fire-Safe Design (Optional): Certain models can be configured with fire-safe features per API 607/API 6FA standards upon request.
- Extended Service Life: Anti-static and blow-out proof stem design enhances safety and operational longevity.

Frequently Asked Questions (FAQ):
-
Q: What is the significance of the JIS F7300 standard for this valve?
A: JIS F7300 is a Japanese Industrial Standard specifically for marine valves. It defines requirements for materials, design, testing, and marking, ensuring the valve's suitability and reliability for shipboard service, including resistance to vibration and corrosive marine environments. -
Q: Why is a Full Bore design important, and when should I use it?
A: A Full Bore (or Full Port) valve has an internal diameter equal to the pipeline. This design minimizes pressure drop, prevents clogging in slurry services, and allows for easy pigging (cleaning) of the pipeline. It is recommended for applications where flow efficiency is critical or where line cleaning is required. -
Q: What information is included in the Mill Test Report (MTR)?
A: The MTR is a certified document from the steel mill. It typically includes the heat number, chemical analysis (percentage of carbon, manganese, etc.), mechanical properties (tensile strength, yield strength, elongation), and the results of any supplementary tests like impact tests, verifying the material meets specified standards. -
Q: Can this valve be used with media other than water?
A: Yes. While ideal for seawater, fresh water, and ballast systems, the selection of appropriate seat and seal materials (like PTFE, Nylon, or Metal) allows it to handle a variety of media including oils, gases, and certain chemicals. Please consult with our engineers for your specific media. -
Q: Are different actuation options available for this valve?
A: Absolutely. While standard operation is via a manual lever or wrench, we can equip the valve with pneumatic, hydraulic, or electric actuators for remote or automated control systems. Gear operators are also available for high-torque applications. -
Q: What are the available pressure ratings and sizes?
A: Pressure ratings commonly follow JIS classes (10K, 16K, 20K) or ANSI classes (150, 300). Sizes are customizable. We recommend providing your specific pipeline size (DN or NPS) and required pressure class so we can offer the most suitable model. -
Q: Do you offer valves with different end connections besides threaded?
A: Yes. We provide a range of end connections including flanged (to JIS, ANSI, DIN standards), socket weld, and butt weld ends to ensure compatibility with your existing piping infrastructure. -
Q: What is your typical lead time and packaging for export?
A: Lead time depends on the order quantity and specifications. Standard models may have shorter lead times. For export, valves are typically packaged in wooden cases or crates suitable for sea freight, with protective coatings to prevent corrosion during transit.
