Adjust the valve if the screw tightening (clockwise adjustment) is to slow down the speed, that is, closing the door close the door to adjust the power. If the valve screw loose (counterclockwise adjustment) is the speed becomes faster, that is, increase the closing door closing force. Adjust the amplitude must be controlled in a small range, and each adjustment are tested door fan strength is appropriate, if the amplitude is too large may screw off, resulting in door closers oil spill.
