As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance industrial flow control solutions. Our JIS F7481 Electric Wafer Butterfly Valve embodies our commitment to precision engineering and reliability, designed to meet the rigorous demands of modern industrial applications. This valve combines the trusted JIS standard with a compact electric design, offering superior sealing and control for a wide range of fluid handling systems. With an annual export value reflecting our global reach, we ensure each valve is backed by stringent quality control and comprehensive documentation, including the Mill Test Report.
The core of this product is its integration of a robust electric actuator with a precision-machined wafer butterfly valve body. The compact design is a significant advantage, allowing for installation in space-constrained piping systems without compromising performance. The electric actuator provides precise, automated control over flow rates, enabling seamless integration into PLC-controlled systems and reducing manual labor. The valve disc, typically manufactured from durable materials, rotates 90 degrees to open or close, providing a tight seal with low torque operation. This design minimizes pressure drop across the valve, enhancing system efficiency.
Key Technical Features & Advantages:
- JIS F7481 Compliance: Manufactured to Japanese Industrial Standards, ensuring dimensional accuracy, material quality, and performance reliability suitable for international projects.
- Electric Actuation: Enables remote operation, precise positioning, and easy integration with automation systems for improved process control.
- Wafer Style Body: Designed to be sandwiched between two pipe flanges, providing a lightweight and cost-effective solution with a simplified installation process.
- Compact & Space-Saving Profile: Ideal for retrofit projects or systems where space is limited, reducing overall piping layout footprint.
- Superior Sealing Performance: Utilizes advanced seat materials (options available upon request) to ensure bubble-tight shut-off and long service life, even with varying media.
- Low Maintenance Design: The streamlined construction with fewer external components reduces the need for frequent maintenance.

Frequently Asked Questions (FAQ)
-
What does "JIS F7481" mean for this valve?
JIS F7481 is a Japanese Industrial Standard that specifies the requirements for flanged, wafer, and lug-type butterfly valves. It covers dimensions, materials, pressure-temperature ratings, and testing. A valve built to this standard ensures compatibility with JIS flange dimensions and offers a recognized level of quality and performance. -
What is the main advantage of a wafer-style butterfly valve over other types?
Wafer-style valves are designed to fit between two pipeline flanges using longer bolts. They are typically lighter, more compact, and often more cost-effective than lug-style or flanged-end butterfly valves, making them ideal for applications where space and weight are considerations. -
Can the electric actuator be customized for specific control signals?
Yes. The electric actuators can be specified for simple on/off operation or for modulating control (4-20mA, 0-10V signals). Options for feedback signals (position indication), fail-safe modes (fail-open or fail-close), and local control via handwheel are also available upon request. -
What media is this valve suitable for?
With the appropriate seat and body material selection, this valve series can handle water, air, gases, oils, and many mild chemical fluids. The standard seat material (like EPDM) is suitable for water, while alternatives like PTFE or Viton are offered for more aggressive chemicals. Always confirm media compatibility with our technical team. -
What is included in the "Mill Test Report"?
The Mill Test Report (MTR) is a certified document from the material manufacturer. It provides chemical composition and mechanical property test results (like tensile strength, yield strength) for the metallic components (valve body, disc, stem) used in the valve, ensuring traceability and material conformity to specified grades. -
How does the compact design benefit installation?
The compact design significantly reduces the valve's face-to-face length and overall envelope. This allows for easier installation in tight spaces, reduces the need for extensive piping modifications during retrofits, and can lower the total weight supported by the pipeline. -
What is the typical lead time for an order?
Lead time depends on the valve size, material specifications, actuator options, and order quantity. Standard configurations often have shorter lead times. We provide reliable estimates upon receipt of your detailed inquiry and maintain efficient logistics from our Shanghai base to major global ports. -
Does the 1-year warranty cover both the valve and the electric actuator?
Yes, the standard warranty period covers defects in materials and workmanship for the complete assembled unit—both the valve body and the electric actuator—under normal use and service conditions as specified. Warranty terms and conditions are provided with the product documentation.
