Composite Exhaust Valve

Composite exhaust valve is a barrel shaped valve body, which mainly contains a group of stainless steel balls, rods and plugs. Composite exhaust valve is installed at the pump water outlet or in the water supply and distribution pipeline to remove a large amount of air accumulated in the pipeline, or a small amount of air accumulated at a higher place of the pipeline is discharged into the atmosphere, so as to improve the service efficiency of the pipeline and the pump Valve quickly inhales outside air to protect the pipeline from damage caused by negative pressure.

4.Advantages of Composite Exhaust Valve 

1) Composite exhaust valve has reliable performance. It can discharge a large amount of air in the pipeline and a small amount of gas in the system operation to the outside air at high speed.
2) Composite exhaust valve is easy to maintain, it can be easily removed from the system for maintenance, and the water in the system will not flow out, so there is no need to empty the system.
3) Composite exhaust valve only exhausts and does not drain water. Special structure is adopted for steam and water separation design to ensure no drainage during exhaust. As long as there is pressure in the system, composite exhaust valve will exhaust continuously.
