As a dedicated manufacturer of industrial valves since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing reliable fluid control solutions for demanding environments. Our Marine Compressed Air Ball Valve, engineered in strict compliance with the JIS F7301 standard, is a cornerstone of our product line, designed to deliver unwavering performance and safety in critical marine and offshore compressed air systems. With an annual export value reflecting our global reach, we understand the rigorous demands of international markets, from North America and Europe to Southeast Asia and Africa. This valve is crafted to meet those demands, offering a robust, leak-proof solution for managing compressed air lines where failure is not an option.
This valve is specifically designed for the unique challenges of marine service, handling compressed air in applications such as starting air systems, control air, and general service air lines on vessels and offshore platforms.
- Robust Construction for Marine Duty: Manufactured from materials selected for corrosion resistance in saltwater atmospheres, including bronze, stainless steel (CF8/CF8M), and carbon steel with protective coatings. The full-port or reduced-port design ensures minimal pressure drop, optimizing system efficiency.
- JIS F7301 Compliance: This is a critical feature, as the Japanese Industrial Standard (JIS) F7301 outlines specific requirements for marine valves, including materials, design, pressure testing, and marking. Compliance ensures the valve meets recognized international benchmarks for quality and safety in maritime applications.
- Precise Pressure Management: Rated for pressures from PN1.0 MPa to PN2.5 MPa (approximately 145 PSI to 363 PSI), this valve is built to withstand the operating pressures typical of marine compressed air systems. Each valve undergoes rigorous hydrostatic and pneumatic shell and seat tests to guarantee integrity.
- Superior Sealing and Operation: Features advanced seat materials like PTFE or reinforced PTFE, which provide excellent sealing with low operating torque and high cycle life. The blow-out proof stem design enhances safety, preventing stem ejection under pressure. Operation is smooth via a standard lever, optional locking handle, gear operator, or pneumatic/electric actuators for remote control.
- Versatile Configurations: Available in a wide range of sizes and connection types to fit various piping layouts. Common end connections include JIS flanges, threaded (NPT, BSP), and socket weld ends.
The technical specifications below outline the standard configurations available. Customizations regarding materials, pressure ratings, actuators, and certifications are available upon request to meet specific project requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the significance of JIS F7301 compliance for this valve?
A: JIS F7301 is a Japanese Industrial Standard specifically for marine valves. Compliance ensures the valve is designed, manufactured, and tested to meet rigorous requirements for materials, strength, pressure tightness, and marking suitable for marine service. It is a widely recognized and respected standard in the global shipbuilding industry. -
Q: Can this valve be used with media other than compressed air?
A: While designed and optimized for compressed air service, it can potentially handle other inert gases or fluids compatible with its construction materials (e.g., water, oil). However, the seat material and pressure/temperature ratings must be verified for the specific media. Consultation with our technical team is recommended for non-air applications. -
Q: What types of actuators can be fitted to this ball valve?
A: The valve is designed for easy integration with various actuators. We can supply or configure it with pneumatic (double-acting or spring-return), electric (on/off or modulating), or hydraulic actuators. The appropriate mounting bracket and coupling are provided based on the selected actuator model. -
Q: Are these valves suitable for cryogenic service or very high temperatures?
A: The standard temperature range is -20°C to +150°C with PTFE seats. For lower temperatures (cryogenic) or higher temperatures (up to 200°C or more), special designs with extended stems, low-temperature materials, or metal seats are available. Please inquire about your specific temperature requirements. -
Q: Do you provide documentation like test reports and material certificates?
A: Yes. Standard delivery includes a manufacturer's data report. Upon request and depending on the order, we can provide additional documentation such as material test certificates (MTC), hydrostatic/pneumatic test reports, and certification of compliance with JIS F7301. -
Q: What is the lead time for standard and customized orders?
A: Lead times vary based on size, material, and quantity. Standard configurations in common sizes may have shorter lead times, while customized orders (special materials, actuators, painting) require additional manufacturing time. We provide estimated lead times with every quotation and strive to meet project schedules. -
Q: How do I determine the correct size and pressure rating for my application?
A: You will need the pipe size (Nominal Diameter), the maximum operating pressure and temperature of your system, and the connection type. Our technical sales team can assist you in selecting the correct valve (DN/PN, material, trim) based on your provided system parameters. -
Q: What warranty do you offer on your marine ball valves?
A> We stand behind the quality of our products. Our valves carry a standard warranty against defects in materials and workmanship under normal use and service conditions for a specified period from the date of shipment. Specific warranty terms are provided with our commercial terms and conditions.
