How do the pneumatic valves on the equipment work? For example, in a cylinder, how is the switching function achieved, and where is the gas released?

The gas for two-position on-off valves is released from the solenoid valve, while the gas with a positioner is released from the positioner (the pressure in the cylinder is equal to the pressure output by the positioner). ——What is a solenoid valve?

Pneumatic valves are controlled in two ways: on-off type and control type. The on-off type is generally controlled by solenoid valves, while the control type is usually controlled by positioners!
Turn the valve on and off at the site; by feeling where the instrument air comes from, you’ll know
To solve problems, one needs to take action more often, observe more, think more, use one’s brain actively, and carefully identify and analyze issues. I think the problem of how to remove air isn’t difficult.
