1, the flow direction of the medium should be consistent with the arrow direction of the valve body; 2, self-operated pressure differential control valve should be installed in the return pipe, the valve connected to the pressure pipe, the Other end of the pressure pipe connected to the water supply pipe, The water supply side of the pipe is installed with a 1/2 "ball valve so as to start the function of eliminating clogging 3. A filter should be installed on the water supply pipe in front of the pressure pipe to prevent the valve from losing the automatic adjustment function due to poor water quality 4. The water supply pipe and the pipe The back of the valve before the return pipe should be equipped with pressure gauges, easy to adjust the control pressure. 5, found that the system flow is too large or too small, the possible reason is that pipe fittings installed in the block stuck in the valve plug, Close the 1/2 "ball valve 3-5 minutes, then if it is lighter blocked, you can automatically eliminate, if still can not be eliminated, you have to open the valve check to eliminate clogging. 6, control pressure differential adjustment method: anti-clockwise to adjust the pressure regulator stem to observe the pressure.
