Pneumatic Ball Valves Description
Pneumatic ball valve consists of a ball valve body and a pneumatic actuator. The valve stem is driven by compressed air to rotate 90°, which drives the ball to open and close, realizing rapid medium cutoff or flow control. Its core structure includes:
Ball and seal: The ball surface and the valve seat are sealed with carbide or elastic materials (such as PTFE), and the leakage level can reach ANSI VI level;
Actuator configuration: The pneumatic actuator supports AC220V/380V power supply, with the fastest switching speed of 0.05 seconds/time, and is suitable for PLC/DCS remote control.

Pneumatic Ball Valves
Advantages:
Fast opening and closing: 90° rotation can achieve full opening/closing within 0.05 seconds, and the emergency shut-off efficiency is high;
Low flow resistance: Full-diameter design, fluid resistance is close to the straight pipe section, reducing pumping energy consumption;
Corrosion resistance: Stainless steel (304/316) valve body and fluororubber seal combination, suitable for corrosive media such as acid, alkali, and organic solvents.
Applications
Chemical and petroleum: Control of sulfur-containing oil and gas, highly corrosive liquids (such as sulfuric acid, chlorine and alkali);
Pharmaceutical and food: Sanitary stainless steel ball valves are used for aseptic fluid transportation, meeting GMP clean standards;
Electricity and metallurgy: Rapid shut-off of high-pressure pipelines of high-temperature steam (≤425℃) and ash-containing media.
