These valves are used to vent the cylinders quickly and enhance the cylinder speed. For this, they are screwed directly on the cylinder using the connection 2. Breathing: The air flowing through the control valve can flow continuously from connection 1 to the connection 2. Venting: When the control valve switches over to venting, 1 becomes depressurized. The valve switches to flow from 2 to 3 and the air from the cylinder can be freely vented into the open.
Warning:
Only use with cylinders where sufficient damping is provided in the end positions (adjustable end cushioning, shock absorbers).
