Product Spotlights
As a dedicated manufacturer with a strong focus on marine and industrial fluid control, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our high-performance JIS F7481 10K Marine Wafer Butterfly Valve. Engineered to meet the rigorous demands of shipbuilding, offshore platforms, and coastal installations, this valve is designed for reliable, long-term service in critical applications. Our commitment to quality, backed by ISO9001 certification, ensures that every valve delivers consistent performance and durability. We understand the importance of operational continuity in marine environments, which is why we provide comprehensive full technical support and guarantee the availability of spare parts, offering our clients peace of mind and minimizing downtime.
This valve is constructed to comply with the Japanese Industrial Standard JIS F7481, specifically for marine use, with a pressure rating of 10K. The wafer-style design allows for easy installation between ANSI or JIS flanges, making it a space-saving and cost-effective solution for piping systems. The robust design ensures reliable shut-off and flow control for seawater, ballast, cooling, fuel, and other shipboard services.
Key Features and Technical Advantages:
- Marine-Grade Compliance: Manufactured in strict accordance with JIS F7481 standards, ensuring suitability for marine and offshore applications where corrosion resistance and reliability are non-negotiable.
- Robust Pressure Handling: The 10K pressure rating (equivalent to approx. 1.0 MPa or 150 psi) makes it suitable for a wide range of shipboard system pressures.
- Compact Wafer Design: The wafer type body fits snugly between pipe flanges, secured by bolts. This design reduces weight, saves space, and lowers overall installation costs compared to lug or flanged valves.
- Superior Sealing Performance: Utilizes a resilient seat (options include EPDM, NBR, or PTFE) that provides a bubble-tight seal against the precision-machined disc, minimizing leakage.
-
Durable Construction Materials: Available in various material combinations to suit specific media and environmental conditions. Common configurations include:
- Body: Cast Steel (WCB), Ductile Iron, or Stainless Steel (CF8/CF8M).
- Disc: Stainless Steel (316/316L) or Bronze.
- Stem: Stainless Steel for high corrosion resistance.
- Multiple Actuation Options: Can be supplied with a simple lever lock, manual gearbox, or automated with electric or pneumatic actuators for remote control and integration into ship automation systems.
- Low Torque Operation: The streamlined disc design and high-quality bearings ensure smooth, low-friction operation, reducing wear on the actuator and extending service life.
- Bi-Directional Flow Capability: Designed to seal effectively against flow from either direction, offering flexible installation in the pipeline.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a wafer-type butterfly valve over lug or flanged types for marine use?
A: The wafer design is significantly lighter and more compact, which is a major advantage in shipbuilding where space and weight are at a premium. It installs between flanges using through-bolts, reducing material costs and simplifying installation. -
Q: Can this valve be used with seawater?
A: Yes, it is specifically designed for marine applications. When ordered with appropriate materials like stainless steel (316/316L) body/disc and EPDM or PTFE seats, it offers excellent corrosion resistance for seawater, ballast, and cooling systems. -
Q: What does "10K" pressure rating mean, and is it suitable for high-pressure lines?
A: "10K" refers to a pressure rating of 10 kgf/cm², approximately equal to 1.0 MPa or 150 psi. It is suitable for most general shipboard services like cooling, ballast, and bilge lines. For higher-pressure fuel or hydraulic lines, please consult our team for valve options with higher ratings. -
Q: Do you provide actuators for automated operation?
A: Yes. We can supply the valve as a manual unit (lever or gear) or as a complete package with electric or pneumatic actuators tailored to your control system requirements (voltage, signal, speed). -
Q: How do I ensure I get the correct spare parts in the future?
A: We maintain detailed records for all orders. Providing the valve's serial number or our order reference ensures you receive the exact replacement parts. We recommend purchasing a critical spares kit at the time of order for essential components. -
Q: Is the valve fire-safe certified?
A: While the standard JIS F7481 valve is not inherently fire-safe, we can provide versions with metal-seated or fire-tested designs upon request for applications requiring such certification (e.g., fuel lines). -
Q: What is your lead time for standard sizes?
A: Lead times vary based on size, material, and quantity. Standard configurations in common sizes (DN80-DN300) typically have shorter lead times. Contact us with your specific requirements for an accurate delivery schedule. -
Q: Can you provide documentation like material certificates and test reports?
A> Yes. As an ISO9001-certified manufacturer, we provide full documentation packages, including material test certificates (MTC), pressure test reports, and certificates of compliance, which are essential for marine classification society approvals.
