As a professional valve manufacturer established in 2016, Shanghai Zhibang Valve is committed to delivering reliable and high-performance flow control solutions for global industrial markets. Our JIS F7481 Standard Electric Wafer Butterfly Valve exemplifies our dedication to quality and engineering precision. Designed for demanding applications, this valve combines robust construction with advanced electric actuation, offering a dependable solution for remote or automated fluid control systems where manual operation is impractical.
This valve is engineered to provide exceptional sealing performance and long service life. Its core value lies in its versatility and resilience, featuring an IP65 waterproof rating that ensures reliable operation even in harsh, wet, or dusty environments. With optional 24V DC or 220V AC power supplies and pressure ratings of 5K (PN10) or 10K (PN16), it can be tailored to fit a wide array of project specifications, from water distribution networks to industrial process lines.
The valve's design and construction offer several distinct advantages:
- Precise & Reliable Control: The electric actuator provides accurate on/off or modulating control, enabling seamless integration into Building Management Systems (BMS), SCADA, or other automated control networks.
- Superior Sealing & Durability: The valve utilizes a high-quality elastomer seat (EPDM or NBR) paired with a precision-machined disc (stainless steel or cast iron) to ensure bubble-tight shut-off and resistance to wear and corrosion.
- Easy Installation & Maintenance: The wafer-style design simplifies installation between flanges, reducing space and weight requirements. The modular actuator design allows for easy servicing or replacement without removing the valve body from the pipeline.
- Broad Compatibility: Compliance with the JIS F7481 standard ensures compatibility with a wide range of international flange dimensions and piping systems, facilitating its use in global projects.

Frequently Asked Questions (FAQ)
Q1: What does the "5K/10K" pressure rating mean?
A1: "5K" corresponds to a pressure rating of PN10 (10 bar), and "10K" corresponds to PN16 (16 bar). These indicate the maximum allowable pressure the valve body and seat can withstand under standard conditions.
Q2: Can this valve be used for both on/off and flow control (throttling)?
A2: Yes. The valve is available with either a simple on/off electric actuator or a more advanced modulating actuator. The modulating type allows for precise flow control based on an input signal (e.g., 4-20mA).
Q3: Is the IP65 rating sufficient for outdoor installation?
A3: Yes, the IP65 rating means the actuator is completely protected against dust ingress and against low-pressure water jets from any direction. It is suitable for most outdoor and damp indoor environments.
Q4: What are the main differences between the 24V DC and 220V AC options?
A4: The 24V DC option is often preferred for safety in certain applications and is common in control panels with DC power supplies. The 220V AC option is standard in many industrial power grids. The choice depends on your site's available power source and safety requirements.
Q5: What seat material should I choose?
A5: EPDM is suitable for hot water, cold water, and mild chemicals. NBR is typically used for oils, fuels, and gases. We can advise on the best material based on your specific media (fluid type), temperature, and pressure.
Q6: How is the wafer-style valve installed?
A6: The valve is placed between two pipeline flanges. Long bolts pass through holes in the flanges and the valve body, clamping it securely in place. This design is lightweight and requires less space than lug or flanged-end valves.
Q7: Do you provide custom configurations?
A7: Yes. While we offer standard models, we can customize various aspects such as disc/seat materials, actuator control signals, feedback switches, and paint coatings upon request to meet unique project specifications.
Q8: What is the lead time for orders?
A8: Lead times vary based on order quantity and specific configuration. Standard models typically have shorter lead times. We ship from major ports including Shanghai, Guangzhou, Hong Kong, and Beijing for efficient delivery worldwide.
