Compatible with both GB Standard and ANSI Standard, this versatile valve series excels in high-pressure environments, offering reliable performance across diverse media and operating conditions. Crafted with premium materials such as stainless steel (1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti) and WCB (carbon steel), it ensures exceptional durability, corrosion resistance, and long service life. Whether for on/off control or throttling applications, this series delivers precise operation, supported by flexible pneumatic actuators (AT Series, AW Series) and a customizable design that adapts to user-specific requirements. Ideal for industries requiring dual-standard compliance and high-pressure resistance, this pneumatic butterfly valve is a trusted choice for critical flow management tasks.

Engineered to comply with both GB Standard and ANSI Standard, this valve eliminates compatibility issues in global projects, reducing procurement complexity and ensuring seamless integration with existing systems.
Rated for PN16 to PN40 (1.6MPa ~ 4.0MPa), the series handles high-pressure media with stability, making it suitable for demanding industrial processes where pressure fluctuations are common.
Adopting corrosion-resistant stainless steel alloys and robust WCB carbon steel, the valve resists wear, rust, and chemical erosion, extending service life and minimizing maintenance costs.
Offering double-acting and single-acting (spring reposition) actuator options, the valve adapts to different control needs, providing fast response times and reliable position control.
Structural length, flange size, and sealing materials can be tailored to user requirements and working conditions, ensuring optimal performance for specific applications.
Equipped with a durable plastic position indicator, operators can easily monitor valve status, enhancing operational safety and efficiency.
Ideal for controlling the flow of crude oil, chemicals, and petrochemical products, thanks to its corrosion resistance and high-pressure tolerance.
Used in thermal power plants and nuclear power facilities for boiler feedwater, cooling water, and steam control, ensuring stable operation under extreme pressure.
Suitable for municipal and industrial water treatment, handling raw water, treated water, and wastewater with reliable sealing and flow control.
Applied in steel mills and smelting plants for controlling cooling water, compressed air, and process fluids, withstanding high temperatures and harsh environments.
Perfect for long-distance pipeline networks transporting gases, liquids, and slurries, offering leak-proof performance and easy maintenance.
Yes, the series is designed to meet both GB Standard (GB/12238, GB/12221) and ANSI Standard (API 609, ANSI B16.10), ensuring seamless integration with global piping infrastructure.
The valve seat offers two main options: stainless steel+flexible graphite and PTFE, both providing excellent sealing performance and resistance to high temperatures and chemicals.
Absolutely. The valve’s structural length and flange size can be customized per JB/T79 standard or user-specific requirements, supporting unique project needs.
Double-acting actuators use air pressure for both opening and closing, while single-acting (spring reposition) actuators rely on air pressure for one direction and a spring for the return, enhancing safety during power outages.
Yes. With stainless steel (1Cr18Ni12Mo2Ti) material options and corrosion-resistant seals, the valve excels in handling corrosive media like acids, alkalis, and saltwater.
Note: The structural length and connecting flange size of butterfly valve series can be designed and manufactured as per users' requirements.
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.
