As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. is proud to introduce our high-performance JIS F7481 Stainless Steel Butterfly Valve DN200 with Gearbox Operator. Engineered for demanding industrial applications, this valve combines robust construction with precise flow control, offering a reliable and durable solution for your piping systems. With an annual export value of US$1-1.5 million and a presence in markets worldwide including North America, Southeast Asia, and Europe, our products are trusted for their consistent quality and performance.
This butterfly valve is designed to meet the rigorous requirements of modern industrial fluid handling. Its core value lies in providing a leak-tight seal, smooth operation, and long service life even under challenging conditions, helping you minimize maintenance costs and system downtime.
Detailed Features and Technical Specifications:
- Premium Stainless Steel Construction: The valve body, disc, and stem are manufactured from high-grade stainless steel (304 or 316), providing excellent resistance to corrosion, erosion, and a wide range of chemicals, making it suitable for water treatment, chemical processing, food and beverage, and marine applications.
- JIS F7481 Standard Compliance: Manufactured in strict accordance with the Japanese Industrial Standard JIS F7481, ensuring dimensional accuracy, performance reliability, and interchangeability with other compliant components.
- Efficient Gearbox Operator: The integrated gearbox provides significant mechanical advantage, allowing for easy manual operation of the large DN200 valve even under high differential pressures. It reduces operator effort and enables precise throttling control.
- Superior Sealing Performance: Features a resilient seat (options include EPDM, NBR, or PTFE) that ensures a bubble-tight shut-off. The disc design minimizes turbulence and pressure drop across the valve when fully open.
- Versatile Connection Options: Available in both wafer and lug body styles. The wafer type is designed for installation between pipe flanges, while the lug type allows for end-of-line service and provides threaded inserts for bolt connections, offering installation flexibility.
- Robust Design for High Pressure: Engineered for standard pressure ratings such as PN10 and PN16, capable of handling a variety of industrial fluid services reliably.

Frequently Asked Questions (FAQ):
-
Q: What is the main advantage of a gearbox operator on a DN200 butterfly valve?
A: A gearbox provides a high gear ratio, making it much easier to open, close, or throttle a large-diameter valve against system pressure. It reduces operator effort, allows for precise control, and enhances safety compared to a direct lever operator. -
Q: Can this JIS F7481 valve be used with ANSI flanges?
A: While JIS and ANSI flange dimensions differ, our valves are often designed with consideration for interoperability. Many JIS F7481 valves can be installed between ANSI Class 150 flanges, but it's crucial to verify the specific face-to-face dimensions and pressure rating compatibility for your application. Please consult our technical team for guidance. -
Q: What are the differences between the Wafer and Lug body styles?
A: A Wafer-style valve is installed between two pipeline flanges, with bolts passing through both flanges. A Lug-style valve has threaded inserts (lugs) on both sides, allowing it to be bolted directly to each flange independently. This makes the lug style suitable for end-of-line service or where one side of the pipeline may need to be disconnected. -
Q: Is the seat material customizable?
A: Yes. We offer standard seat materials like EPDM for general water, NBR for oils, and PTFE for aggressive chemicals or high temperatures. The optimal choice depends on your fluid media, temperature, and pressure. We can advise on the best material for your needs. -
Q: What is the typical lead time for this product?
A: Lead times vary based on order quantity and specific configuration (material grade, seat type). Generally, for standard configurations, we maintain stock or can produce within a competitive timeframe. Contact us with your required quantity for an accurate delivery schedule. -
Q: Do you provide any warranty for this butterfly valve?
A: Yes, we provide a standard warranty against material and manufacturing defects. The specific warranty period and terms are provided with the commercial quotation and are based on the product's application and our general terms of sale. -
Q: Can this valve be fitted with an actuator for automated operation?
A: Absolutely. The gearbox operator is typically designed with a square drive input that can be easily adapted to accept electric, pneumatic, or hydraulic actuators for remote or automated control systems. Actuator mounting kits are available upon request. -
Q: What information do you need to provide an accurate quote?
A: To provide a precise quotation, please specify the required quantity, preferred material (304 or 316 stainless steel), seat material, connection type (wafer or lug), pressure rating, and any special requirements such as actuator needs or additional certifications.
