Open close pneumatic circuits for heavy door

pneumatic system for operating a heavy door typically uses a double-acting cylinder controlled by a 5/2 directional valve.

Opening the door: Pressing a button activates the valve, directing air to the cylinder's extend side, which pushes the door open.
Closing the door: Pressing another button directs air to the retract side of the cylinder, causing the door to close.
Additional components like limit switches, check valves, and flow control valves may be used to ensure smooth operation and safety.
