Compound exhaust valve
Product overview
The compound exhaust valve is installed at the pump outlet or in the water distribution pipeline, which is used to remove the air accumulated in the pipe, so as to improve the use efficiency of the pipeline and the water pump. Once the negative pressure is generated in the pipe, the valve quickly sucks in the outside air to prevent the pipeline from being damaged due to the negative pressure.
