In any pipeline system—whether it's water distribution, wastewater treatment, or industrial processing—air management plays a crucial role. One often overlooked yet essential component in this process is the air valve. Specifically, Air Valves Single and Double are engineered to enhance pipeline performance and prevent damage caused by air accumulation.
At resilientgatevalve, we take pride in manufacturing high-quality air valves along with a full range of flow control products such as Resilient Seated Sluice Valves, Metal Seated Sluice Valves, Non Return Valves, and Pressure Reducing Valves. This article will guide you through everything you need to know about air valves and help you decide which type suits your application best.
What Are Air Valves and Why Are They Important?
Air valves are specialized devices installed on pipelines to release trapped air and admit air as needed. These valves protect the system from vacuum conditions, reduce energy loss, and prevent pipe rupture or water hammer.
Without air valves, pipelines can suffer from pressure fluctuations, reduced flow efficiency, and even structural damage. Installing the right type of air valve can be the difference between a smooth operation and costly repairs.
Understanding Air Valves: Single vs. Double
1. Single Orifice Air Valve
Function:
The single orifice air valve is primarily used for the continuous release of air from a pressurized pipeline. It typically functions during normal operation when small air pockets form due to turbulence or fluid movement.
Structure:
It has a small orifice at the top and a float mechanism that allows air to escape while preventing water from leaking.
Applications:
Municipal water pipelines
Irrigation systems
Fire protection systems
Industrial pipelines
Advantages:
Prevents air locking
Maintains system efficiency
Compact and easy to install
2. Double Orifice Air Valve
Function:
The double orifice air valve is a combination of a large orifice (used during pipeline filling and emptying) and a small orifice (used during regular operation). It releases large volumes of air when the pipeline is filling and allows air intake when the pipeline is being drained.
Structure:
This valve contains two mechanisms: one for large air release and another for continuous air evacuation, ensuring dual functionality.
Applications:
Long-distance water transmission
Wastewater lines
Pump stations
Systems with rapid changes in flow
Advantages:
Dual functionality
Prevents vacuum conditions
Ensures smooth pipeline operations
Key Differences Between Single and Double Orifice Air Valves
| Feature | Single Orifice Air Valve | Double Orifice Air Valve |
|---|---|---|
| Air Release Capacity | Small air volume | Small and large air volume |
| Primary Use | Continuous air release | Pipeline filling and draining |
| System Suitability | Low-pressure systems | High-pressure or long pipelines |
| Cost | More economical | Slightly more expensive |
| Installation Points | High points in the system | Critical points like pump discharge |

How Do Air Valves Complement Other Valves?
While air valves play a specific role in air management, their function is enhanced when used alongside other flow control valves:
Resilient Seated Sluice Valve Manufacturer:
Perfect for on/off water flow control. Works seamlessly with air valves to prevent water hammer and ensure steady flow.Metal Seated Sluice Valve:
Ideal for abrasive or high-temperature applications. Ensures reliability in tough environments where air management is still essential.Non Return Valve:
Prevents backflow, ensuring one-way fluid movement. Air valves assist by removing trapped air that might hinder NRV performance.Pressure Reducing Valve:
Controls downstream pressure. Air valves ensure pressure remains stable by removing excess air from the system.
Common Installation Tips
To maximize performance, consider the following when installing air valves:
Install at System High Points:
Air naturally rises to the highest points in a pipeline, making this the best location for air valve placement.Use Isolation Valves:
For maintenance, always install an isolation valve below the air valve.Regular Inspection:
Though low-maintenance, air valves should be inspected periodically for debris and function checks.Match the Valve to System Pressure:
Choose air valves based on the working pressure of your pipeline system.
Real-World Applications
Urban Water Supply Systems
Air valves ensure uninterrupted water flow, reduce pressure fluctuations, and prevent burst pipes in city infrastructure.
Agricultural Irrigation Networks
In vast fields with changing elevations, double orifice air valves prevent pipeline damage during start-up and shutdown.
Industrial Cooling Systems
Air removal is essential to maintain flow rate and prevent heat build-up. Single orifice air valves serve this purpose efficiently.
Frequently Asked Questions
Q: Can air valves work with corrosive fluids?
A: Yes. At resilientgatevalve, we offer air valves made from corrosion-resistant materials suitable for a wide range of media.
Q: What size air valve should I use?
A: It depends on pipeline diameter, flow rate, and system design. Our team can help recommend the correct size based on your needs.
Q: Do I need both single and double orifice air valves in the same system?
A: In complex systems, using both types can enhance air management. For example, double orifice at pump discharge and single orifice at high points.
