Description of the difference between solenoid valve and electric valve

1. The process requirements of solenoid valve and electric valve are different.
    Solenoid valves have some special process requirements in the production process. Because the function of the solenoid valve is relatively many, such as shunting, regulating and other functions, the requirements for the sealing performance of the medium and the compressive performance are relatively high, so the price is high.
    The function of the electric valve is relatively simple, mainly to adjust the function in the system, so the price is relatively cheap.
2. They work differently
    The principle of the solenoid valve is to use electric energy as the energy source, and then to drive the electromagnetic coil to perform the switching adjustment function. When the electromagnetic coil is energized, the magnetic attraction is generated to overcome the pressure of the spring to drive the spool. This structure is simple and inexpensive, but can only be realized. switch. Although the electric valve also uses electric power as the energy source, it passes through the electric motor and has three states of opening, closing and half opening.
3. Their use is also different
    Solenoid valve: For the switching control of liquid and gas pipelines, it is a two-DO control. It is generally used for the control of small pipes.
    Motorized valves: Analog adjustments for liquid flow in liquid, gas and wind systems, AI control. In the control of large valves and wind systems, electric valves can also be used for two-position switch control.
