The YUEFENG High-Temperature Pneumatic Butterfly Valve is a compact, high-efficiency flow control solution engineered for fast response and reliable performance in demanding industrial environments. Compliant with GB/12238 and API 609 standards, this valve series integrates a lightweight structure with powerful AT/AW Series pneumatic actuation, offering dual sealing options for both on-off and throttling control of media ranging from clean water to corrosive chemicals.
- Dual-sealing technology: soft-sealed (PTFE/graphite) for leak-proof clean media and hard-sealed for high-temperature, abrasive, or corrosive applications.
- Efficient pneumatic actuation: AT/AW Series with double-acting and spring-return options for rapid opening/closing and easy PLC integration.
- Durable construction: WCB or stainless steel body and disc with PTFE composite bushings for corrosion resistance and reduced friction.
- Customizable design: adaptable structural length, flange size, and material configurations to meet specific industrial process requirements.

Significantly smaller and lighter than traditional gate valves, the Pneumatic Butterfly Valve saves valuable installation space and reduces piping support costs. This makes it an ideal choice for space-constrained systems such as skid-mounted equipment, shipboard piping, and building HVAC systems.
Equipped with AT/AW Series pneumatic actuators (available in double-acting and single-acting/spring reposition options), the valve delivers fast opening and closing responses. This enhances operational efficiency in dynamic processes requiring rapid flow adjustments, while supporting easy integration with PLC and automated control systems.
The valve offers two sealing options: soft-sealed (PTFE/graphite) for leak-proof performance in clean media (e.g., water, food-grade fluids) and hard-sealed for high-temperature, abrasive, or corrosive applications. This versatility allows it to adapt to diverse industrial needs without compromising performance.
The valve body and butterfly plate are crafted from WCB or high-grade stainless steel alloys, while PTFE composite bushings reduce friction between moving parts. This combination of materials ensures corrosion resistance, wear resistance, and extended service life—lowering long-term operational costs.
Structural length, flange size, and sealing materials can be tailored to specific working conditions, such as corrosive media, high pressure, or hygiene requirements. The low flow resistance design minimizes pressure drop, reducing energy consumption for fluid transfer.
Perfect for heating, ventilation, and air conditioning systems, the valve’s fast response, low flow resistance, and compact size optimize energy efficiency and space utilization in commercial and residential buildings.
Soft-sealed (PTFE) options meet strict hygiene standards, making the valve suitable for transferring water, syrup, and other food-grade fluids in processing plants, breweries, and beverage production facilities.
Widely used in water supply networks, sewage treatment plants, and irrigation systems, the valve balances durability and cost-effectiveness for large-scale municipal projects requiring reliable flow control.
Corrosion-resistant materials and compact design make the valve ideal for shipboard piping systems, controlling ballast water, fuel, and cooling fluids in marine and offshore applications.
Resistant to corrosive chemicals (acids, alkalis, solvents) when equipped with ZG1Cr18Ni12Mo2Ti materials and PTFE sealing, the valve ensures safe and reliable operation in chemical processing plants.
No two industrial processes are perfectly identical. When off-the-shelf solutions fall short, our engineering capabilities adapt the hardware to your exact operational reality.
Tailored Dimensional Profiles: If your retrofitting project features non-standard gap lengths, we can machine custom face-to-face dimensions to ensure a perfect, stress-free fit.
Specialized Material Pairing: Our metallurgists assist in selecting the exact combination of body alloys and seat materials to combat your specific chemical cocktails, whether dealing with concentrated sulfuric acid or caustic lye.
Actuator Sizing Optimization: We calculate your exact line pressure, media viscosity, and flow rates to mount the perfectly sized AT or AW actuator, preventing sluggish operation or unnecessary air consumption.
Our technical team acts as an extension of your engineering department, reviewing your P&ID schematics to recommend the optimal valve placement and configuration for maximum system efficiency.
Securing a reliable supply chain for critical infrastructure components is paramount for maintaining uninterrupted production. Partnering with a dedicated manufacturer ensures you receive more than just physical hardware; you gain a strategic operational advantage.
Direct-to-Facility Efficiency: By eliminating intermediary layers, we drastically reduce lead times and procurement costs, ensuring your large-scale project stays on budget and on schedule.
Uncompromising Batch Consistency: Advanced CNC machining centers and automated foundry processes guarantee that the thousandth valve performs exactly like the first, eliminating unpredictable variables in your plant.
Robust Inventory Management: We maintain strategic reserves of standard DN50-DN800 components and raw materials, allowing us to rapidly fulfill urgent bulk orders and minimize your facility's downtime.
Lifecycle Technical Support: From initial specification consulting to post-installation troubleshooting, our dedicated engineering support team ensures your fluid control systems operate at peak efficiency for decades.
Review these technical insights to better understand how our pneumatic butterfly valves integrate into your complex systems.
The valve is designed to seamlessly integrate with both AT Series (AT063D to AT270D) and AW Series (AW20 to AW40S) pneumatic actuators. Depending on your safety protocols, you can select double-acting configurations for standard operation or single-acting (spring reposition) models that ensure a fail-safe closure or opening during a power or air supply failure.
Absolutely. For aggressive environments containing strong acids, alkalis, or industrial solvents, we configure the valve with high-grade stainless steel alloys such as ZG1Cr18Ni9Ti or ZG1Cr18Ni12Mo2Ti. When paired with our advanced PTFE composite seals, the valve offers exceptional, long-lasting resistance to chemical degradation.
One of the primary engineering advantages of this butterfly valve is its highly compact architecture. It typically requires 30% to 50% less face-to-face installation space and is significantly lighter than a gate valve of the same nominal diameter (DN). This drastically reduces the need for extensive structural pipe supports and makes it ideal for tight spaces like skid-mounted units or shipboard piping.
The valve excels at both. While it provides rapid and bubble-tight on-off isolation, the precision of the AT/AW pneumatic actuators allows for highly accurate throttling control. This makes it an excellent choice for dynamic processes that require variable flow rates, such as automated chemical dosing or precise HVAC temperature management.
Our standard production line covers a massive nominal diameter range from DN50 up to DN800, catering to everything from small process lines to major distribution mains. Furthermore, if your specific project requires non-standard structural lengths, unique flange drilling, or specialized material combinations, our engineering team can manufacture custom units tailored precisely to your blueprints.
Note: The main spare parts and sealing-ring materials of butterfly valve series can be designed for options as per real working conditions and users' special requirements.
Note: The strrctural length and connecting flange size of butterfly valve series can be designed and manufactured as per JB/T79 standard or users' requirements.
