The build-up of air in a pipeline restricts the flow of fluid through the pipeline and causes a significant reduction in the pipeline’s efficiency, which shortens its lifespan. In addition to this, it is essential to choose the appropriate size of the valve to ensure the accurate release of air in accordance with the requirements for air flow.
Prevents the production of bubbles and air pockets on the surface – In a pressurized pipeline, one of the most important functions of air release valves is to vent the built-up pressure by releasing the air that has accumulated inside the pipeline. The collected air can lead to cavitation, which can significantly hinder pump operations and corrode the pump or pipeline. Cavitation can also result in the creation of further bubbles.

Requires little to no upkeep – After they have been installed, air release valves do not require routine maintenance or lubrication because of the totally automated nature of these valves and their operation. This results in a reduction in the expenses associated with maintenance and the procurement of replacement components. To guarantee flawless operation, optimum performance, and the absence of any leaks, a periodic examination is essential. The strong and straightforward design of the air release valve eliminates the need for any kind of maintenance.If there is, however, a leakage, the valve must be removed so that it may either be reinspected or replaced. In most cases, a leak may be traced back to particles of debris that have been lodged in the orifice.
Efficient use of energy – Because they prevent the build-up of excessive air pressure, air release valves have the significant benefit of reducing the amount of energy required to operate a system. In most cases, an excessive amount of air in the pipeline system can substantially lower the capacity, which results in an increase in the need for power since the pumps must work harder to maintain the required flow.
The following advantages can be obtained by properly utilizing the air valves:
- Decrease in expenses associated with operations as well as energy consumption
- Decreased air pressure drop
- Reduced waiting times during the filling of the pipe system
- Reduced potential for water hammer effects
- Flow metering with fewer instances of failure or inaccurate readings
- Decreased degree of corrosion
Positioning recommendations for the air valves
Particularly noteworthy is the combined air valve.Long horizontal routes should have air release or combination valves installed at intervals ranging from 380 to 760 meters.Combination air valves are placed at intervals ranging from 380 to 760 meters for long descents.

When running a pipeline horizontally for a very long distance, it is best practice to alternate between using air release valves and combination air valves at various points along the pipeline. In any case, we wish you the best in figuring out air valves for your needs.
