1. The tightness of the solenoid valve.
The sealing performance of a solenoid valve directly determines whether the solenoid valve will leak. The current solenoid valve seals are mainly hard seals and soft seals. have their own suitable medium.

2. Solenoid valve action sensitivity and reliability
This refers to the sensitivity of the solenoid valve to the change of the medium parameters and respond accordingly. For solenoid valves used to adjust medium parameters such as throttle valves, pressure reducing valves, and regulating valves, as well as solenoid valves with specific functions such as safety valves and pigging valves, their functional sensitivity and reliability are very important technical performance indicators .

3, is the opening and closing speed of the switch
The opening and closing speed is expressed by the time required for the solenoid valve to complete an opening or closing action. Generally, there are no strict requirements for the opening and closing speed of the solenoid valve, but some working conditions have special requirements for the opening and closing speed. Some require rapid opening or closing to prevent accidents, and some require slow closing to prevent water hammer, etc. , which should be considered when selecting the type of solenoid valve.

4. It is a problem of medium circulation
The recirculation of the medium is suitable for the product pressure. Therefore, when designing the solenoid valve, the resistance of the solenoid valve to the medium should be reduced as much as possible.
