As a professional valve manufacturer with years of expertise, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance JIS F7480 Pneumatic Butterfly Valve with Double Acting Actuator. Engineered for reliable and efficient flow control in demanding industrial applications, this valve combines robust JIS standard construction with precise pneumatic actuation. Our commitment to quality, backed by ISO9001 certification, ensures that every valve delivers consistent performance, durability, and value for our global clientele across North America, Europe, Asia, and beyond.
This valve series is designed to meet the rigorous requirements of modern piping systems. The core of its design is the integration of a JIS F7480 standard butterfly valve with a powerful double-acting pneumatic actuator, providing excellent shut-off and modulating capabilities for liquids, gases, and slurries.
- Robust JIS Standard Design: Manufactured in strict compliance with JIS F7480 standards, ensuring dimensional accuracy, material integrity, and reliable performance compatible with JIS flange systems.
- Efficient Double-Acting Actuator: The pneumatic actuator operates with air supply to both sides of the piston, providing powerful torque for opening and closing. It offers fast response and is ideal for applications requiring frequent operation or fail-safe in the last position.
- Wide Size and Pressure Range: Available in a comprehensive range from DN50 to DN600, with flange pressure ratings of 5K (approx. PN10) and 10K (approx. PN16), offering flexibility for various system design pressures.
- Superior Sealing Performance: Features a precision-machined disc and a resilient seat (options include EPDM, NBR, PTFE) that ensures bubble-tight shut-off and long service life, minimizing leakage and maintenance.
- Durable Construction Materials: The valve body is typically constructed from high-grade cast iron or ductile iron, with stainless steel (CF8/CF8M) available for corrosive applications. The shaft is usually stainless steel for strength and corrosion resistance.
- Versatile Application Scope: Suitable for a wide array of industries including water supply and treatment, chemical processing, HVAC, power generation, food and beverage, and general industrial services.
- Easy Installation and Maintenance: The flanged design allows for straightforward installation between pipeline flanges. The modular actuator design facilitates easy maintenance or replacement without removing the valve from the line.
- Optional Configurations: Various accessories are available, including limit switches, solenoid valves, positioners, filter regulators, and manual overrides, allowing for customized automation control systems.

Frequently Asked Questions (FAQ)
Q1: What is the main difference between a 5K and a 10K flange rating on this valve?
A1: The 5K and 10K ratings refer to the pressure-temperature class of the JIS flange. A 10K flange is designed to withstand higher pressures at a given temperature compared to a 5K flange. The selection depends on your system's maximum operating pressure. We can advise on the suitable rating for your application.
Q2: Can this valve be used for throttling or flow control, or is it only for on/off service?
A2: While excellent for on/off service, this pneumatic butterfly valve is also well-suited for throttling or modulating flow control when paired with a pneumatic positioner. The positioner receives a control signal (e.g., 4-20mA) to precisely position the disc, allowing for proportional flow regulation.
Q3: What are the available options for the valve seat material, and how do I choose?
A3: Common seat materials include EPDM for general water and mild chemicals, NBR for oils and fuels, and PTFE for high temperatures and aggressive chemicals. The choice depends on the fluid media, temperature, and required chemical resistance. Please provide your service conditions for our recommendation.
Q4: Is a manual override feature available for the pneumatic actuator?
A4: Yes, a manual override mechanism is available as an optional accessory. This allows for manual operation of the valve in case of air supply failure or during maintenance, providing an additional level of operational safety and convenience.
Q5: What is the typical lead time for an order of these valves?
A5: Lead time varies based on order quantity, size, and material specifications. Standard configurations often have shorter lead times. We maintain efficient production planning and can provide an estimated delivery schedule upon receipt of your detailed inquiry.
Q6: Do you provide complete packages including accessories like solenoid valves and limit switches?
A6: Absolutely. We can supply the valve as a complete automated package, including the pneumatic actuator, solenoid valve, filter regulator, limit switches, and any other specified accessories, pre-assembled and tested for your convenience.
Q7: Are these valves suitable for use with potable water?
A7: Valves configured with appropriate, certified seat materials like EPDM that meet relevant drinking water standards (certifications available upon request) can be used for potable water applications. Please specify this requirement when inquiring.
Q8: What kind of after-sales support and warranty do you offer?
A8: We stand behind our products with a standard warranty period. Our technical team provides support for installation guidance, troubleshooting, and spare parts supply. Our established export experience ensures we can effectively support international clients.
