Pneumatic inflatable butterfly valve is a type of butterfly valve that achieves efficient sealing through a combination of pneumatic actuation and inflatable sealing structure.
Its core features are as follows:

• Actuation mode: Equipped with a pneumatic actuator (piston or diaphragm type), which drives the valve stem to open and close the disc via compressed air.
• Sealing mechanism: An inflatable sealing ring (made of rubber or elastic material) is installed at the valve seat. When inflated, the sealing ring expands and tightly adheres to the edge of the disc to form a seal; when deflated, the ring contracts to reduce friction and facilitate valve operation.
• Core advantages: Adjustable sealing force, zero leakage (especially suitable for low-pressure / vacuum environments), and excellent wear resistance. It is ideal for shut-off or regulation of media such as powder, granules and fluids containing impurities.

Pneumatic Triple Eccentric Soft-Sealed Butterfly Valve is a high-performance control valve specially designed for high-pressure, high-temperature and high-wear working conditions.
Adopting a triple eccentric structure plus soft sealing technology, it achieves zero-leakage sealing and low-friction operation.
Widely used in complex pipeline systems in chemical, power, metallurgy, environmental protection and other industries, it is an ideal solution to the problems of high leakage rate and short service life of traditional butterfly valves.

Pneumatic Three-Position Butterfly Valve is an automated valve driven by compressed air, with three controllable working positions (usually full open, full close, and intermediate regulating position).
It is suitable for pipeline systems requiring precise flow control or multi-state switching, and is widely used in chemical, environmental protection, energy, water treatment and other fields.

It realizes quick shut-off or regulation of pipeline media through rotation (0°~90°). Featuring both corrosion resistance and high strength, it is widely used in scenarios with high anti-corrosion requirements, such as chemical industry, food, pharmaceuticals and seawater treatment.

The pneumatic PVC butterfly valve is a lightweight control valve specially designed for pipeline systems conveying corrosive media. Adopting a combination of a PVC valve body and pneumatic actuation, it safely shuts off and regulates the flow of acidic, alkaline, salt solutions and neutral fluids. Featuring excellent corrosion resistance, low flow resistance and cost-effective performance, it is widely used in low-pressure piping systems in industries such as chemical engineering, water treatment, environmental protection and food processing.

Pneumatic Powder Butterfly Valve is an automatic control valve specially designed for dry materials such as powder, granules and dust.
Powered by compressed air, it realizes rapid shut-off, regulation or diversion of materials through the rotation of the butterfly disc.
It is widely used in powder conveying systems in chemical, food, pharmaceutical, building materials and other industries.

Pneumatic lined fluorine butterfly valve is an automatic control valve specially designed for highly corrosive media. Adopting a structure of fully lined fluoroplastic + pneumatic actuator, it realizes safe shut-off and precise flow regulation for high-risk media such as acids, alkalis and solvents. Widely used in chemical, pharmaceutical, environmental protection, printing and dyeing industries, it is an ideal choice for severe corrosive working conditions.

Pneumatic flanged hard-sealed butterfly valve is a high-performance control valve specially designed for high-temperature, high-pressure and severe wear working conditions.
It adopts a combination of metal hard sealing technology, flanged connection and pneumatic actuation to achieve precise regulation and reliable shut-off for steam, heat transfer oil, and media containing particles.
Widely used in industrial fields such as electric power, metallurgy, chemical industry and building materials, it serves as key equipment ensuring the safe operation of pipeline systems under harsh working conditions.

Pneumatic control butterfly valve is an automatic valve powered by compressed air. It realizes the regulation of medium flow rate and pressure in the pipeline by precisely controlling the opening degree of the butterfly plate (continuously adjustable from 0° to 90°). It is widely used in industrial scenarios requiring continuous flow control, such as chemical industry, petroleum, water treatment, HVAC and other fields.
