How do two three-position four-way valves control a cylinder?

Two three-position four-way air valves control one cylinder according to the following steps:

1. Connect the air pipes: connect the air pipes of two three-position four-way valves to the air inlet and air outlet of the cylinder. Ensure that the trachea is connected correctly to avoid air leakage or blockage.

2. Set the initial state: set the two three-position four-way air valves to the initial state, that is, both air valves are in the non-working state. At this time, both ends of the cylinder are open, and no air pressure acts on the cylinder.

3. Control cylinder action: By controlling the on-off state of two three-position four-way gas valves, the cylinder can expand and contract.
