Teach you how to select the solenoid valve according to the parameters

Solenoid valve product selection should pay attention to several basic parameters, such as operating mode, fluid medium, solenoid valve material requirements, temperature and so on. The basic parameters of solenoid valve products can be different according to the following introduction. Users need to select the model according to the following data:
1, Type: 2 pass, 3 pass, 4 pass, 5 pass. The connection of the solenoid valve means that the valve body has several interfaces that are not connected 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 may be used, and the normally closed solenoid valve may be selected instead.
3, fluid medium: air, water, oil, steam. This is based on different choices of electromagnetic valve transmission medium solenoid valve products.
4, material requirements: brass, stainless steel, aluminum, plastic. According to the electromagnetic valve material and durability and life cycle selection.
5, size requirements: diameter, diameter, flow coefficient. This is based on the flow rate selection of the solenoid valve.
6. Connection method: G thread, E thread, NPT thread, flange. Threaded valves are mainly used for valves with a nominal diameter of less than 50mm. The installation and disassembly of flanges are relatively convenient and expensive. They are more cumbersome than threaded valves, and they are adaptable to various pipe diameters and pressure connections. Other special models require a welded connection.
7. Pressure requirements: inlet pressure, outlet pressure, maximum operating pressure difference, minimum operating pressure difference. This is selected based on the actual working pressure of the solenoid valve.
8, temperature: ambient temperature, medium temperature. The solenoid valve product is selected according to the environment and the temperature of the medium. This is also related to the material of the solenoid valve. Different material 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 solenoid valve voltage selection.
11. Other requirements: Manual operation, mounting bracket. Due to the different working environments, there may be special requirements when selecting a user.
The user must choose the type according to the inherent factors of the working environment when selecting the solenoid valve. Otherwise, the incorrect selection of the model will cause the solenoid valve to be unstable or even unable to work. And the solenoid valve model and working conditions can not meet the environmental working conditions. It is easy to cause a malfunction of the solenoid valve, damage the solenoid valve product, and cause damage to the user.
