As a professional valve manufacturer with a strong commitment to maritime industry standards, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our JIS F7300 5K/10K Marine Ball Valve. Engineered specifically for the demanding environments of marine engineering, this valve series represents our dedication to providing reliable, durable, and compliant fluid control solutions for shipbuilding, offshore platforms, and port facilities. With our ISO9001 certified manufacturing processes and an annual export value reflecting global trust, we ensure each valve meets the rigorous performance criteria required for safe and efficient marine operations. The inclusion of a comprehensive Mill Test Report with every unit provides full traceability and quality assurance, giving engineers and procurement specialists the confidence they need for critical applications.

Our JIS F7300 Marine Ball Valves are designed to control the flow of seawater, ballast, fuel oil, lubricating oil, and other fluids onboard vessels and marine structures. They are constructed to withstand corrosive saltwater atmospheres, constant vibration, and the pressure fluctuations common in marine systems. The robust design ensures long service life with minimal maintenance, a crucial factor for operations where downtime is costly and access for repairs can be challenging.

Key Features & Technical Advantages:

JIS F7300 Compliance: Manufactured in strict accordance with the Japanese Industrial Standard for ship valves, ensuring compatibility and reliability for vessels built to international and Asian standards.
Dual Pressure Rating: Available in both 5K (PN10) and 10K (PN16) pressure classes, offering flexibility for different system pressure requirements from low-pressure services to more demanding applications.
Superior Corrosion Resistance: Offered in a range of materials including Cast Steel with protective coatings, 316 Stainless Steel, and Duplex Steel to match the specific corrosiveness of the medium and operating environment.
Reliable Sealing Performance: Utilizes advanced seat materials such as PTFE or reinforced PTFE for tight shut-off and low operating torque, with metal-seated options available for high-temperature services.
Versatile End Connections: Supplied with flanged ends (JIS 5K/10K, ANSI, DIN standards), threaded (NPT, BSP), or butt-weld ends to integrate seamlessly into existing piping systems.
Multiple Actuation Options: Standard manual operation with a lockable lever handle is available, alongside optional gear operators, pneumatic actuators, and electric actuators for remote or automated control systems.
Full Documentation: Each valve is supplied with a complete Mill Test Report (MTR), providing chemical and mechanical property certificates for the materials used, ensuring full material traceability for quality audits and classification society approvals.

Frequently Asked Questions (FAQ)

What is the significance of the JIS F7300 standard for marine valves?
JIS F7300 is a Japanese Industrial Standard specifically for valves used on ships. It defines requirements for design, materials, manufacturing, testing, and marking, ensuring the valves are suitable for the harsh marine environment. Using JIS-compliant valves is often required or preferred for vessels being built or serviced in Asian shipyards or for owners specifying these standards.
What is the difference between 5K and 10K pressure ratings?
The "K" rating denotes pressure class in the JIS system. 5K corresponds roughly to PN10 (10 bar), and 10K corresponds to PN16 (16 bar). The choice depends on the maximum working pressure of your specific piping system. We offer both to cater to different application pressures onboard.
What is included in the Mill Test Report (MTR)?
The MTR is a certificate from the material mill that provides verified data on the chemical composition and mechanical properties (like tensile strength, yield strength, impact values) of the raw materials (e.g., castings, forgings, bars) used to manufacture the valve body and critical components. It is essential for quality verification and classification society approvals.
Can these valves be used for both seawater and fuel oil lines?
Yes, but the material selection is critical. For seawater services, we typically recommend 316 Stainless Steel or Duplex Steel for superior corrosion resistance. For fuel oil lines, Cast Steel with appropriate coatings is often suitable. Please consult with our engineers for the optimal material selection based on your specific fluid media.
Do you offer fire-safe certified versions of this valve?
Fire-safe design features, such as secondary metal seals that function in case the primary soft seal is damaged by fire, are available as an option. Please specify your requirement for fire-safe certification (e.g., API 607, API 6FA) when inquiring.
What actuation methods are available?
The valve is available with a standard manual lever handle. For larger sizes or high-pressure applications, we offer bevel gear or worm gear operators. For automated systems, we can supply the valve fitted with pneumatic (air) actuators or electric motor actuators. Actuator selection depends on your available power source and control requirements.
What is your lead time for standard sizes?
Lead times vary based on size, material, and quantity. Standard configurations in common sizes often have shorter lead times. We recommend contacting our sales team with your specific list for an accurate production and delivery schedule.
How do I ensure I order the correct valve for my application?
To ensure a perfect match, please provide the following details: Fluid media, operating pressure and temperature, pipe size and connection standard, required material, preferred operation type (manual/auto), and any special requirements (fire-safe, low temperature, etc.). Our technical team will assist in the selection.
