As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance marine valves for global markets. Our JIS F7480 10K Marine Butterfly Valve series, available from DN50 to DN800, is engineered to meet the rigorous demands of marine and offshore applications. We combine robust construction, reliable sealing, and operational efficiency to deliver a product that ensures system integrity and safety. With an annual export value of US$1-1.5 million and a presence across continents from North America to Southeast Asia, our commitment to quality and customer support is proven.
This valve series is designed for critical flow control in seawater cooling systems, ballast handling, fire mains, and other shipboard piping networks. Key features include:
- JIS F7480 Compliance: Manufactured to Japanese Industrial Standards, ensuring compatibility with international marine piping specifications.
- 10K Pressure Rating: Suitable for working pressures up to 10 kgf/cm², providing dependable performance under standard marine operating conditions.
- Broad Size Range: Available from DN50 (2") to DN800 (32") to accommodate various pipeline diameters.
- Durable Construction: The valve body is typically made from high-grade cast steel or ductile iron, offering excellent corrosion resistance and mechanical strength.
- Superior Sealing: Utilizes resilient seat materials like EPDM, NBR, or PTFE, ensuring bubble-tight shut-off and long service life even with abrasive media.
- Multiple Operation Options: Can be supplied with a manual lever, gear operator, or automated actuator (pneumatic/electric) for remote control integration.
- Flanged Connection: Features JIS standard flanges for secure and leak-free installation.
- Low Torque Operation: The disc design minimizes operating torque, making manual handling easier and reducing actuator size requirements.
- Bi-Directional Flow: Effective for flow control in either direction, enhancing installation flexibility.
- Maintenance-Friendly: Some models feature a top-entry design, allowing for seat replacement without removing the valve from the pipeline.

Frequently Asked Questions (FAQ)
Q1: What does the "10K" pressure rating mean for this valve?
A: The "10K" designation indicates that the valve is rated for a nominal pressure of 10 kgf/cm² (approximately 142 psi or 0.98 MPa). This is a standard pressure class suitable for many marine piping systems, including cooling water, ballast, and general service lines.
Q2: Are these valves suitable for seawater service?
A: Yes, they are designed for marine environments. We offer body materials like cast steel with protective coatings and disc/seal materials such as stainless steel and EPDM or PTFE, which provide good resistance to corrosion from seawater. The exact material combination can be customized based on your specific media and service conditions.
Q3: Can I get valves with actuators for automated control?
A: Absolutely. While standard models come with manual levers or gear operators, we can supply the valves pre-fitted with pneumatic (air) or electric actuators. Please specify your required torque, control signal (e.g., 4-20mA, on/off), and fail-safe mode when inquiring.
Q4: Do you provide documentation like test certificates and material reports?
A: Yes, standard documentation includes a manufacturer's data report, and material test certificates can be provided upon request. Our ISO9001 quality system ensures traceability and proper documentation.
Q5: What is included in the warranty?
A: Our warranty covers defects in materials and workmanship under normal use for a specified period. The exact terms will be detailed in the sales contract. Our technical support team is also available to assist with any operational issues.
Q6: Are the flanges compatible with ANSI or other international standards?
A: These valves are manufactured with JIS 10K standard flanges as per the F7480 specification. While dimensions differ from ANSI, adaptor flanges or transition spools are available upon request to connect to ANSI, DIN, or other piping systems.
Q7: What is the typical lead time for an order?
A: Lead time depends on the size, material, quantity, and any special configurations (like actuators). Standard sizes in common materials typically have shorter lead times. We can provide a specific delivery schedule upon receipt of your detailed inquiry.
Q8: How do I select the right seat material (EPDM, NBR, PTFE)?
A: Seat material selection depends on the fluid temperature and chemical compatibility. EPDM is suitable for hot water and mild chemicals, NBR is common for oils and fuels at moderate temperatures, and PTFE offers excellent chemical resistance and a wider temperature range. Our technical team can help you choose based on your application.
