Electric parallel gate valve: used for analog adjustment of medium flow in liquid, gas, and air system pipelines, and is AI controlled. Electric parallel gate valves can also be used for two position switch control in the control of large valves and air systems.
Electric parallel gate valve: can have AI feedback signal, can be controlled by DO or AO, and is more commonly seen in large pipelines and air valves.
1. Switch form: Electric parallel gate valves are generally driven by motors, and the opening or closing action requires a certain amount of time for analog measurement, which can be adjusted.
2. Job nature: Electric parallel gate valves are generally driven by motors, which are more resistant to voltage surges. Electromagnetic valves are quick opening and quick closing, generally used in places with low flow and low pressure, requiring high switching frequency. Electric parallel gate valves are the opposite. The opening of the electric parallel gate valve can be controlled, with states including open, closed, and half open/half closed, which can control the flow rate of the medium in the pipeline. However, the solenoid valve cannot meet this requirement.
