Choosing a Solenoid Valve

Various types of solenoid valves are used in different applications. Choosing the correct valve for your application is crucial. It's important to choose a valve that can withstand the pressures and environments involved. It's also vital to know whether the valve can work with hardwired controls.

Some of the main components of a solenoid valve are the core tube, ferromagnetic plunger, and stem. All of these parts are used to regulate the flow of fluids.

When a magnetic field is applied to the core, the plunger moves upwards and down. The valve opens and closes depending on the position of the plunger. The core spring returns the core to its original position when the magnetic field is removed.

The material used for the valve body depends on the environment and the fluid it is designed for. Stainless steel and polyvinylidene fluoride are some materials used. They provide the best corrosion resistance and strength. However, they are not ideal for high temperature applications.

The process fluid affects the pH, temperature, and pressure of the fluid. It's also important to consider the type of seal used. It's a good idea to use a different type of seal for each type of media.

The material of the valve seat also varies depending on the application. Some solenoid valves use a diaphragm instead of a disc. A diaphragm is a good option for keeping the fluid pressure under control. It's also a good idea to use an electronic control to eliminate frictional effects.
