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.

To assist technical directors and procurement specialists in their evaluation process, we have compiled detailed responses to the most critical engineering inquiries regarding this pneumatic valve series.
What specific actuator models are compatible with this valve series?
The valve is natively designed to integrate with the AT Series (AT063~DAT270D) and AW Series (AW20~AW40S) pneumatic actuators. Depending on your fail-safe requirements, you can specify either double-acting configurations or single-acting (spring reposition) models. Actuator sizing is precisely calculated based on the valve's nominal diameter (DN) and the maximum differential pressure of your pipeline.
Can this valve be utilized for precise throttling control, or is it strictly for on-off applications?
Yes, it is highly capable of both. While it excels at rapid, bubble-tight on-off isolation, equipping the pneumatic actuator with a smart electro-pneumatic positioner transforms it into a highly accurate throttling device. This allows for granular flow regulation, making it ideal for variable-flow processes like chemical dosing or HVAC temperature balancing.
How does the dual-sealing technology perform in highly corrosive environments?
Exceptionally well. For highly corrosive media such as strong acids or alkalis, we configure the valve with high-grade stainless steel components (ZG1Cr18Ni9Ti or ZG1Cr18Ni12Mo2Ti) paired with a virgin PTFE soft seal. This specific material matrix is chemically inert to most aggressive solvents, ensuring long-term resistance to chemical degradation and maintaining a leak-proof boundary.
What is the standard nominal diameter range, and how do you handle custom sizing requests?
Our standard production line covers a wide nominal diameter (DN) range from DN50 up to DN800, accommodating the vast majority of industrial applications. However, if your project requires custom diameters, non-standard structural lengths, or specific flange drillings, our engineering department will design and manufacture bespoke units to perfectly align with your unique pipeline architecture.
In terms of installation footprint, how does this pneumatic valve compare to traditional alternatives?
This valve series offers a massive spatial advantage. Due to its optimized structural design, it is typically 30% to 50% more compact and significantly lighter than traditional gate valves of the exact same nominal diameter and pressure rating. This makes it the superior choice for tight installations, such as skid-mounted modular systems, shipboard piping networks, or retrofitting within congested facility galleries.
Note: The structural length and connecting flange size of gate valve series can be designed and manufactured as per users' requirements.
