As a specialized manufacturer with ISO9001 certified production since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to present our precision-engineered JIS F7480 Wafer Style Butterfly Valve. Designed for demanding industrial applications, this valve combines the reliability of Japanese Industrial Standards with the superior corrosion resistance of 316 stainless steel and a full bore design for minimal pressure drop. We serve a global clientele across North America, Europe, Asia, and beyond, exporting over US$1 million annually, ensuring that our products meet the rigorous requirements of diverse markets and applications.
This valve is engineered for performance and longevity. Key features and benefits include:
- Superior Corrosion Resistance: The body and disc are constructed from 316 stainless steel, offering excellent resistance to a wide range of corrosive media, including chlorides, making it suitable for chemical, marine, and food processing applications.
- Full Bore Design: Provides an unobstructed flow path equal to the pipeline diameter, significantly reducing pressure loss and allowing for easy passage of cleaning pigs or inspection tools.
- JIS F7480 Compliance: Manufactured in strict accordance with Japanese Industrial Standard F7480, ensuring dimensional accuracy, pressure ratings, and performance reliability trusted in industries worldwide.
- Robust Wafer Style Construction: The compact wafer design is lightweight, saves space, and is installed between two pipeline flanges using through-bolts, making installation and maintenance straightforward.
- Versatile Seating Options: Available with PTFE or EPDM seats to suit different temperature ranges and fluid compatibilities, ensuring a reliable bubble-tight seal.
- Multiple Actuation Methods: Can be supplied with a manual lever for quick operation, a gearbox for higher torque applications, or configured for automated pneumatic/electric actuation.

Frequently Asked Questions (FAQ)
-
Q: What is the main advantage of a "Full Bore" design in a butterfly valve?
A: A full bore design has an internal diameter that matches the pipeline's inner diameter. This minimizes flow restriction, reduces pressure drop, allows for easier cleaning (pigging), and is often preferred for applications requiring high flow efficiency or where line cleaning is necessary. -
Q: Can this JIS F7480 valve be installed in a pipeline system using ANSI flanges?
A: While JIS and ANSI flange standards have different dimensions, our wafer-style valve can often be installed between ANSI flanges using appropriate adapters or by checking specific dimensional compatibility. It's recommended to confirm face-to-face and bolt circle details before installation. -
Q: What media is the 316 stainless steel construction particularly suitable for?
A: 316 stainless steel offers enhanced corrosion resistance, especially against chlorides and acids, compared to 304 stainless steel. It is well-suited for chemical processing, seawater applications, pharmaceutical, food and beverage, and pulp & paper industries. -
Q: What are the available seat material options and how do I choose?
A: Standard seat is PTFE, suitable for a wide temperature range and chemically inert fluids. EPDM is an option for hot water and mild chemicals. NBR is for oils and fuels. Viton (FKM) handles higher temperatures and more aggressive chemicals. Selection depends on fluid type, temperature, and pressure. -
Q: Is this valve suitable for throttling (flow control) applications?
A: While primarily designed for on/off service, this butterfly valve can be used for throttling, especially when paired with a precise actuator (electric or pneumatic). The disc design and seat material influence its throttling characteristics and lifespan. -
Q: What actuation options are available?
A: The valve can be supplied with a manual lever for simple operation, a worm gear operator for higher torque and precise control, or it can be prepared for the direct mounting of pneumatic (double-acting or spring-return) or electric actuators for automated control systems. -
Q: What pressure classes (10K, 16K) are offered, and what do they mean?
A: These are JIS standard pressure ratings. 10K corresponds to a nominal pressure of 10 kgf/cm² (approx. 142 PSI), and 16K corresponds to 16 kgf/cm² (approx. 227 PSI). The choice depends on your system's maximum working pressure. -
Q: Do you offer lug-style versions of this valve?
A: Yes, a lug-style body version is available as an option. Lug-style valves have threaded inserts (lugs) on the valve body, allowing them to be bolted directly to each flange, which can be beneficial for end-of-line service or when one side needs to be disconnected.
