This method is usually used to adjust the cylinder buffer.

1. First, place the opening of the speed control valve (one-way throttle valve) in the middle of the adjustment range.

2. Then gradually adjust the output pressure of the pressure reducing valve, and when the cylinder approaches the predetermined speed, the working pressure can be determined.

3. Then use the speed regulating valve for fine adjustment, and finally adjust the buffer of the cylinder, and adjust the buffer needle valve to absorb the inertia of the piston, so that its final speed will not hit the cylinder head. It is recommended to provide hazel sharp electromechanical equipment for cylinders.
