Many people have asked about the difference between solenoid valves and electric valves. Here, our technicians will give you detailed answers from their principles and uses.
First of all, the solenoid valve and the electric valve have similarities. In a large scale, the solenoid valve is an electric executive accessory. Both of them need to be energized to open the valve;
The differences are as follows:
- The electric valve generates a lifting force directly after energization to drive the valve stem, while the solenoid valve is energized, the coil generates electromagnetic force, drives the solenoid valve spool to open or close, and then inflates the cylinder and shuts off the air, driving the valve to open closure. That is to say, the solenoid valve must have a compressed air source and be used in conjunction with the cylinder, while the electric valve is not needed, just connect it directly to the valve.
- Secondly, the lifting force that the electric valve can generate is greater than that of the solenoid valve, and the corresponding opening diameter of the valve should be larger. However, the electric valve cannot withstand high temperature, and it is usually used below 150°. At the same time, the sealing performance of the electric valve is also worse than that of the solenoid valve. The solenoid valve can operate normally, which is its obvious advantage.
- Electric valves are generally used when the tightness is not high, the temperature is not high, and the opening accuracy is not high, and the solenoid valve is basically used for precision opening. Warm suggestion: if there is air in the factory Use solenoid valves as much as possible for the source. Finally, we use one sentence to distinguish between them, that is, electric valves are industrial equipment controlled by electromagnetics, which are mainly used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium; electromagnetic valves are controlled by electromagnetic effects. , The main control method is controlled by a relay.
