Short Description:
The valve is suitable for working medium for water pipeline, as a device to eliminate gas pipeline, in order to improve the efficiency of the transmission of water equipment and protection is not the pipeline is not deformed, is the necessary equipment of the pipeline.
Features
1.Can eliminate the gas in the pipeline, reduce resistance, save energy.
2.When the pipeline negative pressure, the product can automatically suck air to prevent pipeline rupture.
3.Floating ball for stainless steel, long life, safe and reliable.
