Air valve

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.
Note: This model can not be used in sewage pipeline

Features:
1, Reliable Sealing with special design
2, Automatic air releasing and filling without manual operation
3, Dependable performance and long service life
Float ball moves in fixed routine without hitting the shell
4, Short in height than other same kind air vents

Three functions:
1, large amount of air releasing (main vent )
2, small amount of air releasing (small vent overriding)
3, rapid air filling

It allows air to escape when filling the pipe.
It allows air to enter when emptying the pipe (preventing pipe collapse)
It allows continuous automatic control, eliminating accumulated air, even when the system is under pressure.
