As a professional manufacturer with a proven track record since 2016, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance JIS F7480 Butterfly Valve. Engineered for reliability and durability in demanding industrial applications, this valve series combines robust construction with precise control. Our extensive experience exporting to global markets, including North America, Southeast Asia, and Europe, ensures our products meet international expectations for quality and performance. This valve is designed to offer a dependable sealing solution for fluid control systems, providing excellent value for a wide range of industrial and municipal projects.
This butterfly valve series is meticulously crafted to deliver superior performance and long service life. Key features and benefits include:
- Robust Construction: The valve body is made from high-grade ductile iron, offering exceptional strength and impact resistance compared to standard cast iron, ensuring reliability in high-pressure and high-stress environments.
- Superior Sealing Performance: Equipped with an EPDM (Ethylene Propylene Diene Monomer) seal, the valve provides excellent leak-tight closure. EPDM is renowned for its outstanding resistance to water, steam, mild chemicals, and weathering, making it suitable for a broad spectrum of media.
- Precise and Effortless Operation: Each valve comes with an integrated gearbox operator. This design provides significant mechanical advantage, allowing for smooth and easy opening and closing even at higher pressure ratings, reducing operator fatigue and enabling precise flow control.
- Standard Compliance: Manufactured in strict accordance with the JIS F7480 standard, these valves guarantee dimensional interchangeability and performance consistency, which is crucial for system integration and replacement parts in projects following Japanese Industrial Standards or similar specifications.
- Versatile Application Range: Ideal for handling water, air, and other non-aggressive fluids in various sectors including water treatment, HVAC, power generation, chemical processing, and general industrial piping systems.
- Wide Size Availability: Available in a comprehensive range from DN50 (2") to DN300 (12"), providing a solution for different pipeline diameters within a single, coherent product family.

Frequently Asked Questions (FAQ)
Q1: What is the main difference between JIS F7480 and other standards like API 609?
A1: JIS F7480 is a Japanese Industrial Standard specifying dimensions, materials, and testing for butterfly valves. While API 609 is an American Petroleum Institute standard often used in oil & gas. Our valve meets JIS F7480, ensuring compatibility with piping systems designed to this standard, particularly in Asian markets and specific industrial sectors.
Q2: Is the gearbox operator standard for all sizes in this range?
A2: Yes, for this specific product series from DN50 to DN300, a gearbox operator is included as a standard feature. This provides easier operation compared to a simple lever, especially for larger valve sizes and higher differential pressures.
Q3: Can this valve be used for steam service?
A3: With the standard EPDM seal, the valve is suitable for low-pressure saturated steam within its temperature rating (up to approx. 120°C). For higher temperature steam applications, alternative seal materials like PTFE may be required and can be discussed as a customization option.
Q4: What are the available connection types?
A4: The valve is typically designed as a wafer type for installation between two pipeline flanges. A lug-style version, which allows the valve to be bolted directly to the flanges and supports the pipeline weight, is also available as an option. Please specify your requirement when inquiring.
Q5: Does the price include flanges?
A5: No, the butterfly valve is supplied as a unit (body, disc, stem, seat, and gearbox operator). The mating flanges are part of the piping system and are not included with the valve unless specifically requested as part of a package.
Q6: What is the lead time for an order?
A6: Lead time depends on the order quantity and specific configurations. For standard sizes and materials, we generally maintain stock for faster delivery. Our efficient supply chain and multiple shipment ports (Shanghai, Guangzhou, Hong Kong, Beijing) enable us to offer competitive lead times. Please contact us for a precise delivery schedule.
Q7: Are other seal materials available besides EPDM?
A7: Yes, we can offer other elastomer seat materials such as NBR (Nitrile) or Viton® (FKM) upon request to handle different media like oils or more aggressive chemicals. Material selection depends on the specific fluid, temperature, and concentration.
Q8: What kind of warranty do you provide?
A8: We stand behind the quality of our products. Specific warranty terms are provided with the commercial contract and are based on proper installation, operation within specified parameters, and intended use. Our ISO9001 certification underpins our commitment to quality assurance.
