The pilot valve and the main valve are welded together. A brief introduction to the working principle of the four-way valve: When the electromagnetic coil is in a power-off state, as shown in the figure below: the pilot slide valve \u2461 moves to the right under the drive of the compression spring \u2462, and the high-pressure gas enters the capillary tube \u2460 and then enters the piston cavity \u2464. On the other hand, the gas in the piston cavity \u2463 is discharged.
