A pneumatic gate valve is a type of valve that uses compressed air as the power source to control the lifting and lowering of the gate plate to achieve the opening and closing of pipelines. It is a key device in automatic control systems for handling straight-through, fully open or fully closed working conditions.
Pneumatic gate valves are particularly suitable for applications that require full opening or full closing and minimal pressure loss.
| Characteristics | Pneumatic Gate Valve | Pneumatic Ball Valve |
|---|---|---|
| Flow Resistance | Extremely low (similar to a straight pipe when fully open) | Low (but still has local resistance) |
| Opening and Closing Speed | Slow (linear lift, multiple turns/long stroke) | Extremely fast (90-degree rotation) |
| Physical Dimensions | High (especially for rising stem types) | Compact structure |
| Sealing Surface Wear | Has friction during opening and closing | No friction during opening and closing |
| Throttling Capacity | Strictly prohibited for throttling | Not recommended, but can be used briefly for rough throttling |
| Main Applications | Large diameter, high pressure, and low flow resistance required for on-off operations | Medium and small diameters, fast opening and closing required for on-off operations |
If your primary goal is to reduce pipeline resistance and save energy (such as in main water supply lines), or if the pipe diameter is very large, choose a pneumatic gate valve.
If your primary goal is quick shut-off, frequent operation, or if installation space is limited, choose a pneumatic ball valve.
