As a leading manufacturer with a strong commitment to maritime fluid control solutions, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our JIS F7480 Electric Butterfly Valve. Engineered specifically for demanding shipboard environments, this valve is a reliable and efficient solution for ballast and bilge line applications. With our ISO9001-certified production processes and extensive experience supplying global maritime markets, we ensure each valve delivers the durability, precise control, and compliance required for safe vessel operation. Our focus on robust design and consistent quality helps shipbuilders and operators manage critical fluid systems with confidence.
This valve series combines a high-performance butterfly valve design with an integrated electric actuator, offering remote operation and seamless integration into ship automation systems. Key features and advantages include:
- Marine-Grade Construction: Manufactured from materials like ductile iron, bronze, or stainless steel to resist corrosion from seawater and harsh marine atmospheres.
- JIS F7480 Compliance: Flange dimensions conform to the Japanese Industrial Standard F7480, ensuring easy installation and compatibility with existing shipboard piping networks common in many international shipyards.
- Reliable Sealing: Utilizes resilient seat materials such as EPDM or PTFE, providing excellent sealing performance for both ballast water (which can contain solids and organisms) and oily bilge water.
- Electric Actuator Flexibility: Available with various electric actuators offering standard voltages (24VDC, 110VAC, 220VAC) and control signals (on/off, 4-20mA modulating). This allows for centralized control from the ship's bridge or engine control room.
- Fail-Safe Options: Optional fail-safe (spring return) actuators are available to automatically open or close the valve in case of power loss, enhancing system safety.
- Low Maintenance Design: The simple, robust design minimizes moving parts, reducing the need for frequent maintenance—a critical advantage in hard-to-access shipboard locations.
- Customizable Configurations: We offer customization for specific requirements, including different materials, coatings (epoxy, galvanization), limit switches, positioners, and manual overrides.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of using an electric actuator over a manual or pneumatic one for this application?
A: Electric actuators enable remote and automated control from a central location like the bridge, which is crucial for managing ballast and bilge systems efficiently on modern ships. They eliminate the need for crew to access potentially hazardous or inconvenient valve locations manually. -
Q: Is this valve suitable for handling oily bilge water?
A: Yes, when configured with a compatible seat material like NBR or PTFE, the valve can effectively handle oily water mixtures typically found in bilge systems. It is important to specify the fluid composition when ordering. -
Q: How does the JIS F7480 flange standard differ from ANSI or DIN standards?
A: JIS F7480 is a Japanese standard with specific flange dimensions, bolt hole patterns, and pressure ratings. It is commonly used in shipbuilding, particularly in Asian shipyards. While similar in function to ANSI or DIN flanges, the physical dimensions differ, so compatibility with existing JIS-standard piping is assured. -
Q: Can this valve be operated manually if the electric power fails?
A> Yes, most of our electric actuator models can be supplied with a manual override feature (handwheel or crank). This allows for manual operation during power outages or for maintenance purposes. -
Q: What is the typical delivery lead time for a standard size valve?
A: For standard configurations and sizes, our typical lead time is 4-6 weeks after order confirmation. Lead times for customized orders or large quantities may vary and will be confirmed upon inquiry. -
Q: Do you provide any corrosion protection for the valve body?
A> Standard valves feature an epoxy coating for corrosion resistance. For more severe environments, additional protection like hot-dip galvanizing or specialized marine-grade coatings are available upon request. -
Q: Are spare parts readily available?
A: Yes, as the manufacturer, we maintain an inventory of common spare parts such as seals, gaskets, and minor actuator components. We can supply these parts to ensure the long-term operability of your valves. -
Q: Can your valves be integrated with a ship's existing PLC or control system?
A: Absolutely. Our electric actuators can be supplied with standard control signals (e.g., 4-20mA, dry contact) and feedback signals (e.g., open/close limit switches, position feedback) that are compatible with most marine PLC and control systems.
