Overview:

CARX compound exhaust valve consists of main valve and micro-exhaust valve. This valve is installed in the highest point of the pipeline where there is closed air, to improve the efficiency of the pipeline water transmission. When negative pressure is generated in the pipe, this valve quickly sucks in air to prevent damage to the pipeline due to negative pressure. When the pipe is filled with water, the main valve exhausts a lot of air, and when the air is exhausted, the valve closes. When the water flow in the pipe precipitated a small amount of gas gathered to a certain extent, the micro-exhaust valve began to exhaust, in order to prevent the pipe to produce air segregation, affecting the efficiency of the flow, can be customized according to different needs.
