Product Description
Electric Gate Valve For Large-Diameter Pipelines With Zero Pressure Loss And Automatic Shut-Off
The electric gate valve uses an electric actuator to control the lifting of the gate plate, achieving complete opening or complete shut-off of the pipeline automatically. It combines the advantages of low flow resistance and good sealing of the gate valve with the advantages of remote control and high thrust of the electric actuator.
- Automation Control: Remote operation is possible and it can be integrated into SCADA/DCS systems.
- High Output Torque: Electric actuators can provide greater thrust, making them suitable for high-pressure and large-diameter applications.
- Precise Positioning: Equipped with position sensors, it can accurately display the valve status.
- No Air Source Required: Unlike pneumatic valves, it does not need a compressed air system.
- Urban water supply and drainage and sewage treatment
- Power station cooling water and steam systems
- Long-distance pipelines for oil and natural gas
- Large-scale industrial water supply networks
| Characteristics | Electric Gate Valve | Electric Ball Valve |
|---|---|---|
| Flow Resistance | Very low (no difference from a straight pipe when fully open) | Low (but still with the ball as an obstruction) |
| Opening and Closing Speed | Slow (multiple turns/long stroke) | Fast (90° rotation) |
| Sealing Performance | Good (metal seal) | Excellent (soft seal can achieve zero leakage) |
| Thrust/Torque | Requires large thrust | Requires large torque |
| Installation Space | Large height (especially for rising stem type) | Compact structure |
| Applicable Conditions | Large diameter, high pressure, and zero pressure loss required for shut-off (such as main water supply lines in cities, main steam pipelines in power plants) | Medium and small diameters, fast shut-off, and zero leakage required for shut-off |
- Choose electric gate valve: For very large pipe diameters (such as DN300 and above), high working pressure, and situations where pipeline pressure loss is a critical factor (such as main water supply lines in cities, main steam pipelines in power plants).
- Choose electric ball valve: For medium and small diameters where shut-off speed, sealing grade (zero leakage), and installation space have higher requirements.
Electric gate valves are a combination of "powerhouses" and "energy savers" in industrial pipeline systems. With the huge thrust generated by electric actuators, they can drive large-diameter high-pressure gate valves. At the same time, with their nearly zero flow resistance characteristics, they play an irreplaceable role on key trunk lines where the energy consumption of pumping needs to be minimized to the greatest extent. Although they are bulky, slow and expensive, in large-scale pipeline networks that have extreme demands for energy efficiency and high-pressure sealing, they remain the undisputed kings.
