As a professional valve manufacturer with ISO9001 certification, Shanghai Zhibang Valve is proud to present our high-performance JIS F7481 5K Wafer Butterfly Valve. Engineered for reliability in demanding industrial applications, this valve series combines a robust cast iron body with a corrosion-resistant stainless steel disc, offering a durable and cost-effective solution for flow control. Designed to meet the stringent JIS F7481 standard, our valves ensure consistent performance and compatibility with a wide range of piping systems, making them a trusted choice for our global clientele across North America, Southeast Asia, Europe, and beyond.
Our butterfly valves are meticulously manufactured to provide superior sealing, easy operation, and long service life. The core design focuses on minimizing pressure drop and ensuring bubble-tight shut-off, which is critical for process efficiency and safety.
Key Features & Technical Advantages:
- Robust Construction: The combination of a cast iron body (providing strength and vibration dampening) and a stainless steel disc (ensuring excellent corrosion resistance and durability) creates a valve built to withstand harsh operating conditions.
- JIS F7481 Compliance: Manufactured in strict accordance with the Japanese Industrial Standard F7481 for wafer-type butterfly valves, guaranteeing dimensional accuracy, performance reliability, and interchangeability.
- 5K Pressure Rating: Rated for a nominal pressure of 5K (approximately 0.5 MPa), suitable for a broad spectrum of low to medium-pressure applications in water, air, and other non-aggressive fluids.
- Versatile Size Range: Available from DN50 to DN300 (2" to 12"), offering flexibility for various pipeline dimensions and flow capacity requirements.
- Superior Sealing: Features a resilient seat (typically EPDM or NBR) that ensures a bubble-tight seal, minimizing leakage and enhancing system integrity.
- Multiple Actuation Options: Can be operated manually via a lever or gearbox, or automated with pneumatic or electric actuators, allowing for integration into automated control systems.
- Easy Installation & Maintenance: The wafer design simplifies installation between flanges without the need for nuts on the valve side, reducing installation time and cost. The compact design also saves space.

Frequently Asked Questions (FAQ):
-
Q: What does "5K" pressure rating mean?
A: "5K" is a Japanese Industrial Standard (JIS) pressure class, approximately equivalent to 0.5 MPa (5 bar, ~73 psi). It indicates the maximum allowable pressure the valve is designed to handle. -
Q: Can this valve be used for hot water applications?
A: Yes, with the standard EPDM seat, it is suitable for temperatures up to 120°C. For higher temperatures, alternative seat materials like Viton can be explored. -
Q: What is the difference between a wafer and a lug-style butterfly valve?
A: A wafer valve is installed between two flanges using longer bolts. A lug-style valve has threaded inserts (lugs) allowing it to be installed using bolts only on one side, useful for end-of-line applications. Our standard is wafer type; lug type is optional. -
Q: Is the stainless steel disc suitable for corrosive fluids?
A: The standard stainless steel (CF8/304) offers good resistance to many mildly corrosive environments like water, air, and certain chemicals. For highly corrosive media, SS316 disc material is available upon request. -
Q: Do you provide valves with actuators?
A: Yes. We can supply the valve as a manual unit (lever/gear) or fully assembled and tested with pneumatic or electric actuators to meet your automation needs. -
Q: What certifications does your manufacturing process hold?
A: Our production is certified under the ISO9001:2015 Quality Management System, ensuring consistent quality control throughout the manufacturing process. -
Q: What is the lead time for an order of DN150 valves?
A: Standard sizes are typically available from stock. For larger or customized orders, lead times vary; please contact our sales team with your specific quantity and configuration requirements for an accurate timeline. -
Q: From which ports do you ship?
A: We ship globally from major Chinese ports including Shanghai, Guangzhou, Hong Kong, and Beijing, ensuring flexible and efficient logistics.
