Pneumatic Butterfly Valve, 304 Stainless Steel, DN100, Quick-Assembly Ventilation
A pneumatic butterfly valve is an industrial valve that controls the flow of fluids by rotating a butterfly plate through a pneumatic actuator. It is often the preferred choice in most medium and low pressure, large diameter industrial applications.
Similar to other pneumatic valves, to achieve automatic control, the following accessories are required:
| Characteristics | Pneumatic Butterfly Valve | Pneumatic Ball Valve | Pneumatic Gate Valve |
|---|---|---|---|
| Structural Length | Shortest | Short | Longest |
| Opening and Closing Speed | Fast (90°) | Very Fast (90°) | Slow (Linear Multi-turn) |
| Flow Resistance | Small | Small (Full Bore) | Minimal |
| Regulation Performance | Good | Poor | Prohibited |
| Sealing Performance | Soft Seal: Zero Leakage Metal Seal: Poor |
Excellent (Soft Seal) | Good |
| Main Diameter | Advantageous in Medium and Large Diameters | Advantageous in Medium and Small Diameters | Large Diameter, High Pressure |
| Cost | Low (Especially for Large Diameters) | Medium | High |
Pneumatic butterfly valves are the "versatile all-rounders" and "value-for-money champions" in industrial pipeline automation. They strike an ideal balance between functionality, cost, and space occupation. Although they have some limitations in high-pressure, high-temperature, and small-diameter applications, in their main battlefield - medium and low pressure, large-diameter on-off and regulation applications, they have become one of the most widely used pneumatic valves thanks to their unparalleled comprehensive advantages. Whether it's simple on-off control or complex flow regulation, you can always find a pneumatic butterfly valve that suits your working conditions.
