Lectotype of electric valve and solenoid valve: difference between electric valve and electromagnetism

Recently, many customers came to our company to ask for quotations. The solenoid valves and electric valves on their quotations belong to the same product, but in fact, they are not.
Now let me explain the detailed parameters of electric valves and solenoid valves.
Solenoid valve: the solenoid valve is usually controlled by the 220V power supply and power supply. The solenoid valve also belongs to the electric execution accessory. The two of them require electricity to open the valve, but the electric valve and the solenoid valve can produce a lift directly after the electrified valve, thus driving the valve stem and solenoid valve. After electricity, the coil produces electromagnetic force to drive the valve core open or close. The solenoid valve is widely used in the control of hydraulic and air pressure, control the state of cylinder and cylinder, and is used in the oil and gas control components. It acts like an electric contactor.
Electric valve: electric valve is usually the pipe diameter, widely used in fluid flow, stop, flow, pressure and so on control, flow, pressure control called electric valve; flow, stop control called electric switch valve. And the electric valve to produce lifting force to be higher than the solenoid valve, the same can open the valve larger diameter, but the electric valve has a disadvantage is the high temperature, the temperature is more than 140 degrees, the use of electric valves will easily lead to damage to the motor. Compared with the solenoid valve, the sealing performance is also poor, and it is also easy to cause the movement distortion when the stem is raised.
