Air Valve

The air valve is a special valve used to prevent decompression waves during transients from creating a negative pressure in the tube. It is usually installed in the normal operation of the pipeline when the hydrodynamic pressure is low, during the transient flow process, there may be a high point of liquid column separation.
Air is taken in when the pressure inside the pipe is lower than atmospheric pressure and is exhausted when the pressure in the pipe rises above atmospheric pressure. During the exhaust process, the valve can automatically close when the liquid in the tube is filled with the pipe, and the liquid is not allowed to leak into the atmosphere.
Designed with the scientific principle, it has compact structure as well as endurable service life. Manufactured by our company as a reliable distributor, which is also one of the manufacturers, it is of high quality. It is one of the good solutions to wholesale the air valve from our factory with excellent service.
