Product Description

1.Composite exhaust air valve

Composite exhaust air valve is a barrel shaped valve body, which mainly contains a group of stainless steel balls, rods and plugs. Composite exhaust air 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.

3.Application scope of Composite exhaust air valve

Composite exhaust air valve is used at the highest point of the sewage pipe or the place with closed air. It dredges the pipe by removing the gas in the pipe to achieve normal work.
Composite exhaust air valve is used in independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system.

4.Advantages of Composite exhaust air valve

1) Composite exhaust air 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 air 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 air 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 air valve will exhaust continuously.
