As a professional manufacturer with a solid foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing high-performance fluid control solutions for demanding industrial applications. Our JIS F7481 Electric Butterfly Valve, certified by both ABS and NK, is engineered specifically to meet the rigorous standards of the shipbuilding and offshore industries. This valve represents our commitment to reliability, safety, and operational efficiency in critical marine environments, offering a robust and dependable solution for your piping systems.
This valve combines precise electric actuation with a design compliant with the Japanese Industrial Standard F7481, ensuring compatibility and performance in a wide range of marine applications. From ballast and bilge systems to cooling water, fuel oil, and general service lines on vessels and offshore platforms, this valve delivers consistent shut-off and control. We understand the importance of minimizing downtime and ensuring crew safety, which is why every valve is built to withstand harsh sea conditions and provide long-lasting service.
Key Features & Technical Advantages:
- Dual Certification for Marine Assurance: The ABS (American Bureau of Shipping) and NK (Nippon Kaiji Kyokai) certifications are not just stamps; they are a testament to the valve's design, material selection, manufacturing process, and quality control meeting the strict rules of these leading marine classification societies. This provides peace of mind for shipyards, owners, and operators.
- JIS F7481 Standard Compliance: Manufactured in accordance with JIS F7481, this valve guarantees dimensional interchangeability and performance benchmarks recognized globally in shipbuilding, particularly in Asian markets.
- Reliable Electric Actuation: The integrated electric actuator allows for remote operation, precise flow control, and easy integration into automated ship management systems. Options for different control signals (e.g., 4-20mA, 0-10V) and voltages are available.
- Robust Construction for Harsh Environments: The valve body is typically constructed from durable materials like cast iron or cast steel, with corrosion-resistant coatings. The disc and stem are often made from stainless steel to prevent seizing and corrosion.
- Superior Sealing Performance: Utilizing high-quality seat materials such as EPDM, NBR, or PTFE, the valve ensures tight shut-off even after numerous cycles, suitable for various media including seawater, oil, and air.
- Compact & Lightweight Design: Compared to gate or globe valves, the butterfly design offers a significant space and weight saving, a critical factor in ship design where every kilogram and cubic meter counts.
- Low Maintenance & Easy Installation: The simple design translates to easier installation, inspection, and maintenance, reducing lifecycle costs. The wafer or lug style connection simplifies piping integration.

Frequently Asked Questions (FAQ):
-
Q: What is the primary advantage of having both ABS and NK certification on this valve?
A: Holding dual certification from ABS and NK significantly broadens the valve's acceptance in international shipbuilding. Many shipowners and yards require equipment certified by specific societies. Having both covers a wider range of project requirements, streamlining procurement and approval. -
Q: Can this electric butterfly valve be used for modulating (throttling) control, or is it only for on/off service?
A> We offer both on/off and modulating control versions. The electric actuator can be specified with proportional control (e.g., 4-20mA input) for precise flow regulation in applications like cooling systems. -
Q: Are the valves supplied with the actuator pre-mounted and tested?
A> Yes, as a standard practice, the electric actuator is assembled, calibrated, and tested with the valve body before shipment. This ensures proper operation and saves installation time at your site. -
Q: What are the available options for the electric actuator's power supply and control signal?
A> Common options include AC 110V, 220V, 380V, 440V, 50/60Hz and DC 24V. Control signals can be dry contact, 4-20mA analog, or 0-10V. Please specify your requirements. -
Q: How does the JIS F7481 standard differ from other butterfly valve standards like API 609 or ISO 10631?
A> JIS F7481 is a Japanese standard widely adopted in Asian shipbuilding. It defines specific dimensions, pressure-temperature ratings, and testing requirements tailored for marine use. While functionally similar, dimensional differences may affect direct interchangeability with API or ISO valves. -
Q: What kind of maintenance does this valve typically require?
A> Maintenance is minimal. Periodic checks of the actuator's operation and lubrication (if specified) are recommended. The seat and disc may require inspection/replacement after extended service depending on the media and cycle count. -
Q: Can you provide valves with materials suitable for handling seawater or aggressive chemicals?
A> Absolutely. We can recommend and supply valves with body coatings (epoxy, etc.), stainless steel discs (316SS), and chemically resistant seat materials like PTFE or Viton to handle corrosive media. -
Q: What is your lead time for standard sizes of this certified valve?
A> Lead times vary based on size, material, and actuator specifications. For standard configurations, typical production lead time is 4-8 weeks. We recommend contacting us with your detailed needs for an accurate schedule.
