Product Description
Pneumatic Gate Valve, Wear-Resistant, Slag Discharge, Corrosion-Resistant, Used For Coal Ash And Dust Discharge In Power Plants
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.
- Minimal flow resistance: When fully open, the gate is lifted completely above the valve cavity, creating a direct passage with almost zero flow resistance. This is its most prominent advantage.
- Excellent sealing performance: When fully closed, the sealing surfaces can achieve either a hard metal-to-metal seal or a soft seal, ensuring good sealing effect.
- Suitable for high pressure: The structure is robust, and there is no friction between the sealing surfaces during opening and closing, enabling it to withstand high pipeline pressure.
- Unrestricted flow control direction: The medium can flow in from either side without affecting the performance.
- Valve body and gate material: Choose based on medium pressure, temperature and corrosiveness.
- Sealing material: Hard seal (metal) or soft seal (rubber, PTFE).
- Structural form: Rising stem vs. Non-rising stem; Parallel vs. Wedge.
- Actuator: Double-acting vs. Single-acting (fail-safe position).
Pneumatic gate valves are particularly suitable for applications that require full opening or full closing and minimal pressure loss.
- Water supply and sewage treatment: Control of main pipeline on-off, as its flow resistance is small, it can save pumping energy consumption.
- Oil and gas industry: Long-distance pipelines for crude oil and natural gas.
- Power industry: Boiler feed water and steam systems.
- Chemical industry: Large-diameter, high-pressure process pipelines.
| 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.
