As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for demanding global markets. Our Butterfly Valve for Marine and Offshore Applications, designed in full compliance with the JIS F7480 standard, represents our commitment to reliability and durability in the harshest environments. Engineered to withstand corrosive seawater, high pressure, and extreme operational conditions, this valve is a critical component for ensuring the safety and efficiency of marine and offshore systems. With over seven years of manufacturing expertise and an annual export value exceeding one million USD, we deliver robust solutions trusted by clients across North America, Southeast Asia, Europe, and beyond.
This marine-grade butterfly valve is meticulously crafted to meet the stringent requirements of shipbuilding, offshore platforms, and coastal facilities. Its design focuses on providing a secure, long-lasting seal and smooth operation under continuous use.
- Superior Corrosion Resistance: Key components like the disc and body are available in materials such as stainless steel CF8M (316) or nickel-aluminum bronze, offering exceptional resistance to saltwater corrosion, pitting, and biofouling.
- Robust Construction & Leak-Proof Design: The valve features a sturdy, pressure-rated body and a precision-engineered disc that ensures a bubble-tight shut-off, crucial for ballast, cooling, and fuel oil systems.
- Compliance & Traceability: Manufactured strictly according to JIS F7480, the valve guarantees performance consistency and material traceability, which is essential for classification society approvals.
- Versatile Actuation Options: To suit various control needs, the valve can be fitted with a manual lever, gear operator, or automated electric/pneumatic actuators, enabling easy integration into remote control systems.
- Low Maintenance & Easy Operation: The streamlined design minimizes flow resistance and pressure drop. The seated design allows for simple inline maintenance without removing the valve from the pipeline.
- Wide Application Range: Ideal for seawater cooling, firefighting, bilge and ballast systems, tank venting, and cargo handling on vessels, FPSOs, and offshore rigs.

Frequently Asked Questions (FAQ)
Q1: What is the JIS F7480 standard, and why is it important for marine valves?
A1: JIS F7480 is a Japanese Industrial Standard specifically for marine butterfly valves. It defines requirements for materials, design, pressure ratings, and testing to ensure suitability for shipboard and offshore use. Compliance is often required or highly recommended by marine classification societies for safety and reliability.
Q2: Can this valve be used for both seawater and oil/fuel applications?
A2: Yes, but the seat material must be selected accordingly. We offer EPDM or NBR for general water service and specialized materials like PTFE or HNBR for fuel oil and hydrocarbon services. Please specify your media during inquiry.
Q3: What are the main differences between wafer, lug, and flanged connection types?
A3: Wafer valves are sandwiched between two pipeline flanges, suitable for bidirectional flow. Lug valves have threaded inserts allowing them to be installed at the end of a pipeline or between flanges without long bolts. Double flanged valves have integral flanges for bolting directly to pipeline flanges, offering the highest mechanical strength.
Q4: Do you provide valves with actuators for automated control systems?
A4: Absolutely. We can supply the valves fitted with electric or pneumatic actuators suitable for remote operation. Actuator specifications (torque, voltage, control signal) can be customized to match your control panel requirements.
Q5: What is the typical lead time for an order?
A5: Lead time depends on order quantity, specifications, and material availability. For standard configurations, we typically ship within 30-45 days. Expedited production may be available upon request.
Q6: Which marine classification society approvals do your valves hold?
A6: While our manufacturing is ISO9001 certified, specific classification society approvals (like ABS, DNV, LR, BV) are typically obtained by the shipyard or end-client through product testing and documentation review. We provide all necessary material certificates and test reports (e.g., PMI, NDT) to support such approval processes.
Q7: Are spare parts like seals and gaskets available for long-term maintenance?
A7: Yes, we maintain an inventory of critical spare parts and can supply complete maintenance kits for our valves. This ensures you can perform repairs efficiently and extend the valve's service life.
Q8: Can you customize the valve for non-standard sizes or special coatings?
A8: Yes, we offer engineering support for custom sizes, special pressure ratings, and applied coatings like epoxy or rubber lining for enhanced corrosion protection. Please provide your detailed specifications for a feasibility assessment.
