How to choose the solenoid valve selection according to the parameters

The selection of solenoid valve products should pay attention to several basic parameters, such as the operation mode, the fluid medium to be adapted, the material requirements of the solenoid valve, and the temperature. The basic parameters of the solenoid valve products can be based on the following introductions. The user selection is also based on the following data:
1, type: 2 pass, 3 pass, 4 pass, 5 pass. The solenoid valve has several interfaces on the valve body that are not connected to each other and are connected to different pipes of the system. For example, there are three oil passages that are three links.
2, operation mode: normally open type, normally closed type, universal type. This is judged according to the opening time of the solenoid valve in the pipeline. If the solenoid valve in the pipeline needs to be opened for a long time, the normally open solenoid valve can be selected, and the normally closed solenoid valve is selected.
3. Fluid medium: air, water, oil, steam. This is a different solenoid valve product depending on the choice of the solenoid valve delivery medium.
4, material requirements: brass, stainless steel, aluminum, plastic. According to the material and durability of the solenoid valve and the service life.
5, size requirements: pipe diameter, diameter, flow coefficient. This is based on the flow rate selection under the working condition of the solenoid valve.
6, connection: G thread, E thread, NPT thread, flange. Threaded valves are mainly used for valves with a nominal diameter of 50mm or less. The flanges are easy to install and disassemble. They are expensive and more cumbersome than threaded valves. They are suitable for pipe connections of various diameters and pressures. Other special models require a soldered connection.
7. Pressure requirements: inlet pressure, outlet pressure, maximum operating pressure difference, minimum operating pressure difference. This is based on the actual working pressure of the solenoid valve.
8, temperature: ambient temperature, medium temperature. Select the solenoid valve product based on the temperature of the environment and the medium. This is also related to the material of the solenoid valve. Different materials of solenoid valve products have different high temperature and low temperature resistance.
9, use occasions: explosion-proof grade, IP protection grade
10, voltage: AC / DC, voltage value, single / double coil, wire / DIN socket type. According to the voltage selection of the solenoid valve.
11, other requirements: manual operation, mounting brackets. Due to the different working environments, there may be special requirements when selecting users.
When the user selects the solenoid valve, it must be selected according to the inherent factors of the working environment. Otherwise, the wrong selection of the model will result in unstable or even inoperable malfunction of the solenoid valve. And the type and working conditions of the solenoid valve can not meet the working conditions of the environment. It is easy to cause the solenoid valve to malfunction, damage the solenoid valve product, and cause losses to the user.
