Structural principle of three position three way solenoid valve

Three position three way solenoid valve is a common control component commonly used for controlling gases or liquids such as carbon dioxide, air, steam, etc. It includes a valve body, a valve core, and two coils, with each valve core having three positions: P, T, and R. P and T represent the inlet and outlet, respectively, while R is the transitional position in the middle. When the valve core is in the P and T positions, the valve opens and gas enters the valve body from the P position and is discharged from the T position. When the valve core is in the P and R positions, the valve closes and the gas stays in the pipeline, which is equivalent to the valve being in a closed state. When the valve core is in the R and T positions, gas enters the valve body from the R position and is then discharged from the T position.
