Product Description
Combined Type Air Vent Air Release Valve 

(CARX) Combined Type Vacuum Breaker Air Release Valve

Combination Type Air Release Vent Valve 
 (both single oriface and double oriface are available)

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 vent disc is open and releases a large number of gas; when there is no gas and the valve is full of water, SS ball floats up to drive the valve disc close the vent port and stop air release. 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 so at this moment gas is exhausted from vent port. When the pump stops working, the tube 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
