As a professional manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in producing high-performance industrial valves for global markets. Our JIS F7481 Large Diameter Butterfly Valve is engineered for reliable, long-term service in demanding flow control applications. Combining a robust 316 stainless steel body with a PTFE seat and manual lever operation, this valve offers an excellent balance of corrosion resistance, tight sealing, and user-friendly control, making it a trusted choice for engineers and procurement managers worldwide.
This valve is designed to meet the rigorous JIS F7481 standard, ensuring dimensional interchangeability and performance consistency. Its construction is focused on durability and minimal maintenance, providing significant lifecycle cost savings for your operations. Whether you're managing water treatment plants, chemical processing lines, or HVAC systems, this valve delivers the performance you need.
Core Features & Technical Advantages:
- Superior Corrosion Resistance: The valve body is crafted from 316 stainless steel, which offers enhanced resistance to chlorides and a wide range of corrosive media compared to standard 304 stainless steel. This material choice extends the valve's service life in harsh environments.
- Excellent Seal Integrity: The PTFE (Polytetrafluoroethylene) seat provides a bubble-tight shut-off. PTFE is known for its chemical inertness, low friction, and ability to handle a broad temperature range, ensuring reliable sealing even after numerous cycles.
- Robust Large Diameter Design: Engineered specifically for large pipeline applications, the valve's design ensures structural integrity and smooth operation even at high diameters, minimizing pressure drop and flow turbulence.
- Simple & Reliable Manual Operation: The manual lever operator allows for quick, quarter-turn operation from fully open to fully closed. It provides clear visual indication of the valve position and requires no external power source, making it ideal for locations where power is unavailable or for emergency isolation.
- JIS Standard Compliance: Manufactured to JIS F7481 specifications, this valve guarantees precise dimensions, flange compatibility, and performance metrics that are recognized and trusted in many international markets, particularly in Asia.
- Versatile Configuration Options: The valve is available in various configurations to suit specific needs, including wafer or lug body styles for different piping system requirements. Pressure ratings (like PN10, PN16) and specific port sizes are customizable upon request.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of the JIS F7481 standard for this butterfly valve?
A: The JIS F7481 standard specifies precise dimensions, performance requirements, and testing methods. Using a valve built to this standard ensures reliable interchangeability with other compliant components in your system and provides a clear, internationally recognized quality reference. -
Q: Why choose 316 stainless steel over 304 for the valve body?
A: 316 stainless steel contains molybdenum, which significantly increases its resistance to corrosion from chlorides (like salt) and many industrial chemicals. This makes it the preferred material for more aggressive environments, offering greater long-term durability. -
Q: Is the PTFE seat suitable for high-temperature applications?
A: PTFE seats have a wide operational temperature range, typically from approximately -20°C to 200°C. For specific high-temperature limits or alternative media, please consult our technical team for seat material recommendations. -
Q: Can this manual lever valve be later converted to an actuated (electric/pneumatic) version?
A> Yes, the design of this butterfly valve often allows for the later addition of a pneumatic or electric actuator. The manual lever can usually be replaced with an actuator mounting kit. Please inquire about compatibility for your specific valve size. -
Q: What are the available connection types for this large diameter valve?
A> We typically offer both wafer and lug body styles. Wafer valves are designed to be installed between two flanges with through-bolts, while lug valves have threaded inserts allowing them to be installed at the end of a pipeline. The choice depends on your piping system design. -
Q: How do I determine the correct pressure rating (PN) for my application?
A> The pressure rating should be selected based on the maximum working pressure and any potential surge pressures in your system. Common ratings include PN10 and PN16. Our sales engineers can assist you in selecting the appropriate rating. -
Q: What is your lead time for custom-sized large diameter valves?
A> Lead times vary based on the specific size and quantity. As a manufacturer, we have control over our production schedule. Once we receive your detailed requirements, we can provide an accurate delivery timeline. -
Q: Do you provide documentation like test reports or material certificates?
A> Yes, as an ISO9001 certified manufacturer, we can provide standard documentation, including material test certificates. More detailed inspection and test reports (e.g., for hydro-testing) are available upon request.
