The hydraulic fluids move through the ports, triggering the spring. Valve and hydraulic fluids regulate how fast the door moves when being opened and closed. When it closes, it’s opposed by a hydraulic fluid which regulates the speed that the door shuts.
The door’s mechanism to close comes with three different settings: back check, speed of swing, and latch speed. Back check provides resistance, and lets you control how large the door opens. Speed of swing determines the speed at which you close the door. The latch can be adjusted to a speed so that you can control the speed at which the door is locked. The latch and swing speed can be adjusted so that your door is closed in just 5-7 minutes from a 90 degree direction.
It is possible to use a kickdown stopper to stop doors from opening. Or, put one under the handle. Small weights can be placed in the door as long as it’s weight isn’t too large. Make sure to not put the wedge between door hinges or the frame. To stop smoking from spreading, ensure that doors made from commercial wood shut whenever there is flame. mv8eq6qakq.
