Our JIS F7480 Marine Butterfly Valve is engineered specifically for the demanding environments of ship piping systems. We understand that every vessel has unique requirements, which is why we offer extensive customization options to ensure a perfect fit for your specific application, enhancing system reliability and operational efficiency.
This valve is designed to meet the rigorous standards of marine service, offering robust construction and reliable performance for controlling the flow of seawater, ballast water, bilge water, fuel oil, and other shipboard fluids. Our focus is on delivering valves that contribute to the safety, longevity, and maintenance ease of your maritime operations.
Key Features and Technical Advantages:
- JIS F7480 Compliance: Manufactured in strict accordance with Japanese Industrial Standard F7480 for marine valves, ensuring international recognition and suitability for global shipbuilding and repair projects.
- Tailored Custom Design: We work closely with clients to adapt valve specifications—including materials, pressure ratings, connection types, and actuation methods—to match the precise needs of specific ship piping layouts and fluid media.
- Corrosion-Resistant Construction: Utilizing materials such as ductile iron with epoxy coating, cast steel, or stainless steel for the body, paired with discs made from stainless steel or aluminum bronze, to withstand harsh marine atmospheres and corrosive fluids.
- High-Performance Sealing: Available with various seat materials like EPDM for general water, NBR for oils, or PTFE/Viton for chemicals, providing a tight, bubble-tight shut-off and extended service life.
- Low Torque Operation: The optimized disc design ensures smooth, low-torque operation, which is crucial for manual levers and reduces the power requirement for automated actuators, saving energy and cost.
- Compact and Lightweight Design: The wafer-style design offers a space-saving and weight-saving advantage compared to other valve types, a critical factor in ship design where space and weight distribution are paramount.
- Multiple Actuation Options: Can be supplied with manual lever, gear operator, electric actuator, or pneumatic actuator, allowing for integration into local control or centralized automated ship management systems.

Frequently Asked Questions (FAQ):
Q1: What does JIS F7480 standard mean, and why is it important for marine valves?
A1: JIS F7480 is the Japanese Industrial Standard specifically for marine butterfly valves. It defines requirements for materials, design, pressure ratings, testing, and marking. Using a valve compliant with this recognized standard ensures it meets the performance and safety levels expected in marine applications, facilitating approval processes in international shipbuilding and repair.
Q2: How extensive are your customization options for this valve?
A2: Our customization is comprehensive. We can adjust the valve's size (DN), pressure class, body/disc/seat materials, connection type (wafer or lug), and actuation method (manual lever, gearbox, electric, or pneumatic). We tailor these parameters based on your specific fluid, pressure, temperature, piping layout, and control system requirements.
Q3: Which seat material should I choose for seawater service?
A3: For standard seawater applications, EPDM (Ethylene Propylene Diene Monomer) is a commonly recommended seat material due to its good resistance to seawater, ozone, and weathering, along with a wide temperature range. For higher temperatures or specific chemical exposure, alternatives like PTFE or Viton can be considered.
Q4: Can this valve be used for fuel oil lines on ships?
A4: Yes, it can be configured for fuel oil service. This typically involves selecting appropriate body and disc materials with corrosion resistance (e.g., coated ductile iron or stainless steel) and a seat material compatible with fuel oil, such as NBR (Nitrile Rubber), which offers good resistance to oils and fuels.
Q5: Do you provide valves with actuators for remote operation?
A5: Absolutely. We can supply the valves pre-fitted with electric or pneumatic actuators suitable for marine environments. These actuators enable remote operation and can be integrated into the ship's control panel or automation system, allowing for centralized flow control.
Q6: What is the typical lead time for a custom-designed order?
A6: Lead time varies depending on the complexity of customization and order quantity. For standard configurations with minor modifications, it can be relatively short. For fully custom-engineered solutions, we provide a timeline upon review of your specifications. Our efficient manufacturing processes aim to meet project schedules.
Q7: What kind of testing do these valves undergo before shipment?
A7: Each valve undergoes rigorous factory testing, which typically includes a shell test (body strength) and a seat leakage test to ensure tight shut-off. Testing is performed according to relevant standards. Test certificates can be provided upon request to support your quality documentation.
Q8: How do you ensure protection against corrosion during sea transport and storage?
A8: Valves are properly cleaned, dried, and protected before packing. Internal and external surfaces are coated with suitable rust preventive oils or varnishes. They are then packaged in sealed plastic bags and placed in sturdy export-grade wooden cases to prevent moisture ingress and physical damage during transit.
