As a professional manufacturer with a solid foundation since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in delivering high-performance industrial valves for global markets. Our Gear Operated JIS F7481 10K Wafer Butterfly Valve, designed for pipelines from DN50 to DN600, represents our commitment to engineering robust, reliable, and cost-effective flow control solutions. This valve is engineered to meet the stringent requirements of diverse industries, offering a durable and efficient sealing mechanism suitable for a wide range of media.
The core value of this valve lies in its combination of a standardized design, operational ease, and adaptability. Built to comply with the Japanese Industrial Standard JIS F7481, it ensures compatibility and reliability in international projects. The gear operation mechanism provides precise control and reduces manual effort, making it ideal for applications requiring frequent adjustment or where lever operation is impractical. The wafer-style design facilitates easy installation between flanges, saving space and reducing overall system weight and cost.
- Robust Construction & Material Selection: The valve body is typically constructed from durable carbon steel, while the disc is made from stainless steel to resist corrosion and wear. The seal, available in EPDM or NBR, ensures tight closure and longevity against various fluids.
- Precise Gear Operation: Unlike simple lever-operated valves, the gear operator allows for fine-tuned positioning of the disc, enabling better flow regulation and reducing the risk of seal damage from sudden opening/closing.
- Space-Efficient Wafer Design: Its wafer (flange insert) configuration eliminates the need for separate valve flanges, making it a compact solution that simplifies installation and lowers material costs.
- Broad Size & Application Range: Available in a comprehensive size spectrum from DN50 (2 inches) to DN600 (24 inches), this valve serves numerous sectors including water treatment, HVAC systems, chemical processing, and general industrial piping.
- Standard Compliance & Reliability: Adherence to JIS F7481 standard guarantees consistent dimensions, pressure ratings, and performance, providing confidence in system integration and long-term operation.
Below is a summary of key technical specifications for common sizes:
| Nominal Diameter (DN) | Approx. Inch Equivalent | Pressure Rating (10K) | Typical Body Material |
| 50 | 2" | 10K (approx. 1 MPa) | Carbon Steel |
| 150 | 6" | 10K (approx. 1 MPa) | Carbon Steel |
| 300 | 12" | 10K (approx. 1 MPa) | Carbon Steel |
| 600 | 24" | 10K (approx. 1 MPa) | Carbon Steel |
The advantages of choosing our Gear Operated Wafer Butterfly Valve extend beyond its specifications:
- Cost Efficiency: The wafer design and gear operator offer a balance of performance and affordability compared to more complex valve types.
- Operational Safety & Convenience: The gear mechanism allows for controlled operation, reducing strain on operators and minimizing potential for accidental rapid valve movement.
- System Flexibility: Its wide size range and standard compliance make it a versatile component suitable for system upgrades, new installations, and international procurement requirements.
- Reduced Maintenance: The robust material selection and design contribute to a longer service life with minimal maintenance needs.
For clients, these benefits translate into reliable pipeline performance, simplified installation and maintenance workflows, and overall project cost savings. It is a valve designed for practicality and durability in demanding environments.

Frequently Asked Questions (FAQ):
-
What does "10K" pressure rating mean?
"10K" is a Japanese standard pressure rating, approximately equivalent to a pressure class of 1 MPa (about 145 psi). It indicates the valve's designed maximum working pressure. -
Can this valve be used with aggressive chemicals?
The standard seal materials (EPDM, NBR) suit many common fluids. For highly aggressive chemicals, alternative seal materials like Viton may be available upon request. Please consult with us for your specific media. -
Is the gear operator standardized?
The gear operator is designed to provide a standardized interface for manual operation. The gear ratio and operation torque are engineered for the specific valve size to ensure manageable operation. -
How does the wafer installation differ from a lug-type valve?
A wafer valve is installed between two pipeline flanges using bolts through the flanges. A lug-type valve has threaded inserts (lugs) allowing it to be bolted directly to a single flange. Our valve is primarily wafer-type, but lug design can be an optional feature for certain applications. -
What is the temperature range for the standard EPDM seal?
The standard EPDM seal typically performs well within a temperature range of approximately -20°C to +120°C, depending on the specific fluid and pressure conditions. -
Are these valves suitable for throttling (flow control)?
While butterfly valves can be used for throttling, the gear operator provides better control than a simple lever. However, for precise throttling applications, the specific valve characteristics and system requirements should be evaluated. -
Do you provide installation guidelines or drawings?
Yes, installation guidelines and dimensional drawings are available for all sizes. They can be provided upon request to assist in your project planning. -
Can I order a single size or a mixed set of sizes?
We cater to both bulk orders for specific sizes and mixed orders for projects requiring multiple valve sizes. Please contact our sales team for flexible ordering options.
