Whether the magnetic switch of the cylinder can directly control the solenoid valve.

Generally, the cylinder has a full stroke, and the solenoid valve is controlled to be fully open or closed. If you need to travel on the cylinder, you should add a travel switch.

For example, the steps of opening are:

1. Turn on the knob-the solenoid valve is energized-the compressed air is controlled to flow into the cylinder-when the travel limit is reached, the limit switch signals-the solenoid valve is de-energized, thus stopping in the middle of the travel.

2. Control the solenoid valve with pulse signal, so as to control the compressed air and cylinder stroke; In this control mode, the travel feedback is more accurate; Now some regulating valves are controlled by cylinders, which are more accurate.
