As a professional manufacturer with ISO9001 certified quality management, Shanghai Zhibang Valve is proud to present our high-performance JIS F7480 standard butterfly valves. Engineered for reliability and durability in demanding industrial and municipal applications, these valves offer exceptional sealing performance and long service life. Our focus on precision manufacturing and rigorous testing ensures each valve meets the exacting standards required by our global clientele across diverse markets from North America to Southeast Asia.

This series of butterfly valves is designed to provide efficient flow control in a wide range of systems. The combination of a robust ductile iron body and a resilient EPDM seat creates a valve that is both strong and provides a reliable bubble-tight seal. We understand that different applications require different operation methods, which is why we offer flexible actuation options to suit your specific needs, whether for frequent manual operation or for systems requiring gear reduction.

Key Features & Technical Advantages:

Superior Material Construction: The valve body is crafted from high-grade ductile iron (nodular cast iron), offering excellent tensile strength, impact resistance, and durability compared to standard gray cast iron. This material is less brittle and provides better performance under pressure fluctuations and water hammer conditions.
High-Performance EPDM Sealing: The seat is made from Ethylene Propylene Diene Monomer (EPDM), a synthetic rubber known for its outstanding resistance to water, steam, mild acids, alkalis, and alcohols. It performs reliably across a wide temperature range, typically from -20°C to +120°C, ensuring a long-lasting, leak-free seal.
Flexible Actuation Solutions: Customers can choose the operation method that best fits their system requirements.
- Manual Lever Actuation: Ideal for applications where the valve is operated infrequently or where space and cost are primary considerations. The lever allows for quick 90-degree operation.
- Gear Actuation (Worm Gear Operator): Recommended for larger valve sizes (typically DN200 and above) or applications requiring higher torque, precise flow adjustment, or where the valve is located in hard-to-reach places. The gearbox provides mechanical advantage, making operation smoother and less strenuous.
JIS F7480 Standard Compliance: Manufactured in strict accordance with the Japanese Industrial Standard F7480, ensuring dimensional interchangeability, specified pressure ratings, and performance characteristics that are recognized and trusted in many international markets, particularly in Asia.
Optimized Disc Design: The disc is designed for minimal flow resistance in the open position and provides a smooth, 360-degree sealing surface when closed. It is often nickel-plated or coated to enhance corrosion resistance and reduce friction against the seat.
Versatile Connection Options: Available in standard wafer-type design (suitable for installation between two pipe flanges) or lug-type design (which allows the valve to be installed at the end of a pipeline or to isolate a section). The design conforms to JIS flange dimensions (10K pressure rating).

Benefits for Your Operations:

Reliable Flow Control: Ensures precise regulation or isolation of water, air, and other compatible media in your piping systems, contributing to system efficiency and safety.
Reduced Maintenance Costs: The durable ductile iron construction and high-quality EPDM seat are designed for longevity, minimizing the frequency and cost of replacements and downtime.
Ease of Installation & Operation: The compact wafer/lug design saves space and weight compared to gate valves. The chosen actuation (lever or gear) is engineered for user-friendly operation.
Global Market Compatibility: Built to the widely recognized JIS standard, these valves are suitable for projects and replacements in markets that specify or accept this standard, facilitating procurement and inventory management.

Backed by our ISO9001 certification and nearly a decade of manufacturing expertise since 2016, Shanghai Zhibang Valve delivers products that meet consistent quality benchmarks. Our annual export volume, serving markets from North America and Western Europe to Africa and Oceania, is a testament to the global trust in our valves.

Frequently Asked Questions (FAQ):

Q: What is the main difference between the manual lever and the gear operator option?
A: The manual lever is a simple, cost-effective handle for quick 90-degree on/off operation, suitable for easily accessible valves. The gear operator (worm gear) provides a mechanical advantage, reducing the effort needed to turn the valve, which is crucial for larger sizes (DN200+) or for fine flow control. It also allows for mounting in any orientation and is ideal for valves that are operated frequently or are hard to reach.
Q: Is this valve suitable for potable water applications?
A: With the standard EPDM seat, this valve is commonly used for cold and hot water applications. For potable water, it is essential to confirm that the specific EPDM compound used complies with relevant drinking water standards (like WRAS, KTW, or NSF/ANSI 61), which can be requested from our sales team.
Q: Can this valve be used with fluids other than water?
A: The EPDM seat offers good resistance to a range of media including weak acids, alkalis, alcohols, and steam. However, compatibility with specific chemicals, oils, or solvents must be verified. We can advise on seat material suitability for your specific media.
Q: What flange standard does this JIS valve match? Can it fit ANSI or DIN flanges?
A: This valve is designed for JIS 10K flanges. While the bolt hole circle and dimensions differ from ANSI or DIN standards, it can often be installed between flanges of other standards using suitable adapters or by checking the compatibility of drilling templates. It's recommended to provide your flange standard for verification.
Q: What is the delivery lead time for an order of DN250 valves with gear operators?
A: Lead times vary based on order quantity and current production schedule. For standard configurations, we typically maintain stock for common sizes or can produce within a few weeks. Please contact us with your specific quantity and requirements for an accurate delivery estimate.
Q: Do you offer any other seat materials besides EPDM?
A: Yes. While EPDM is our standard for general water service, we can often provide alternative seat materials like NBR (Nitrile) for oil applications or Viton (FKM) for higher temperature or more aggressive chemical services, subject to request and availability.
Q: Is the valve fully open at 90 degrees?
A: Yes, a quarter-turn (90 degrees) of the lever or gear handle moves the disc from the fully closed to the fully open position, allowing for unobstructed flow with low pressure drop.
Q: What kind of testing do your valves undergo before shipment?
A: In line with our ISO9001 quality system, our valves undergo routine tests which typically include a shell test (body pressure test) and a seat leakage test to ensure integrity and sealing performance before they are approved for shipment.
