The industrial valve market is always diversified and rich, changing and improving constantly to deliver quality products to allied industries. And the exhaust valve is the topic that Dai Nam wants to talk about in this article. Let's find out the importance and application of the exhaust valve!
What is the air release valve?
Air release valve is a line of valves that discharges excess air from the pipeline system, avoiding overpressure and air leakage in the pipeline.

Structure of the air release valve
Each air release valve consists of the following main components:
- Body: cast iron / copper material. Depending on the system and the project to choose the best material.
- Valve cap: usually designed with the same material as the valve body. Usually on the valve cap there is a vent to the environment.
- Ball float: made of light material such as plastic or stainless steel, is attached to a lever coupling to help open and close the plug to release the air.
- Air discharge hole: made of rubber, this button is connected from the float ball through the levers to the air outlet, which moves up and down to circulate the air out.
- Entrance: for small and medium sized pipes, we often use a threaded connection convenient for installation. With industrial systems, valves are connected in a threaded way to create a firm, tight working system. For DN sizes above 50, a flanged connection type air release valve is used.
Types of air release valves
- Automatic air release valve
- Single air release valve
- Dual air release valve
Application of the exhaust valve
- Air valves are used in water pipes, water supply and drainage pipes in urban areas and industrial zones.
- Applications in fire protection systems, closed water systems in chains.
- Air valves are used in irrigation systems, chemical transmission systems, and swimming pools.
- Used in hydroelectric projects, pipelines in oil and gas exploitation, mining.
- Used in boilers and refrigeration systems.

Instructions on how to install and maintain the air release valve
- How to install:
The valve is usually fitted at the end of the fluid flow or at the ends of the manifold segments. When the liquid rushes to the end of the pipeline, the valve will automatically expel the amount of gas in the pipeline. The valve is connected to the pipe by a threaded connection (for small DN) or a flanged connection (for large DN).
- How to maintain:
In the process of air-release valve, if the air release is not regularly checked, some residue will stick in the air vent, causing blockage of the valve. Therefore, we should regularly check the valve, check the sensitivity of the spring, the inner float.
