How to make the cylinder rise faster

There are two screw-like things (speed control valves) on the cylinder. Which direction do you want to go? Hurry up and slow down. Adjust which end of the speed regulating valve (tighten slowly and loosen quickly).

Adjustment principle: adjusting the speed control valve is to adjust the running speed of the cylinder by accelerating or slowing down the exhaust.

Just master this method, because ordinary cylinders are exhaust regulated. Because the exhaust regulation has the characteristics of smooth operation.
