Combination Type Air Release Vent Valve

Δ Brief Introduction : The KARFAR model CARX air vent is in shape of oval barrel. The trim mainly includes stainless steel ball, stem and disc. This air vent is usually mounted at outlet side of  pump or water distribution pipeline. It performs to release the air collected inside so as to improve the working capacity of pump station and pipeline. When the pipeline is under negative pressure, the plug will  open rapidly to fill in air to protect pipeline from negative pressure damage.

Δ Working process:
When water starts filling into pipeline, the air valve disc is in open position and releases gas in large amount; when there is no gas and the valve is full of water, SS ball floats upwards to drive the valve disc to close and stop air releasing. During normal working process, small amounts of gas will be produced in the pipeline. When gas collects to a certain amount, water level falls and the float ball drops down. At this moment gas is exhausted from the small hole. When the pump stops working, pipeline will be empty or under negative pressure. The plug then will open quickly and fill in air to ensure pipeline safety. 

Note: This model can NOT be used in sewage pipeline.
 (We have another air valve model designed specially for sewage pipeline)
