Features of Air Release Valve

Air release valves are designed to automatically vent accumulated air from pressurized piping systems, preventing issues like flow restrictions, pressure surges, and potential damage to the system.

 

Air release valves automatically vent air pockets that accumulate in pipelines, especially at high points, ensuring smooth and efficient flow. The small orifice allows for the release of small amounts of air during system operation, preventing pressure build-up and potential water hammer.

 

Application of Air Release Valve

Water treatment

Air release valves are used to remove air from water treatment systems, such as water distribution systems, water treatment plants, and sewage treatment plants.
Oil and gas production

Air release valves are used to remove air from oil and gas production systems, such as pipelines, tanks, and wellheads.
Chemical processing

Air release valves are used to remove air from chemical processing systems, such as reactors, mixers, and storage tanks.
Power generation

Air release valves are used to remove air from power generation systems, such as steam turbines, gas turbines, and hydroelectric power plants.

Pulp and paper production

Air release valves are used to remove air from pulp and paper production systems, such as paper machines, pulp mills, and recovery boilers.

Mining

Air release valves are used to remove air from mining systems, such as mine dewatering systems, slurry pipelines, and tailings ponds.

Aerospace

Air release valves are used to remove air from aerospace systems, such as aircraft fuel systems, engine starters, and environmental control systems.

 

Components of Air Release Valve

 

Valve body

It contains the inner floats and upper mechanism inside a compact ductile iron body. The body is designed so that the inlet is completely free of float guides, making it possible to use butterfly valves directly under the air valve without sacrificing performance. A lower 316ss grade tamper-proof drain valve is built into each valve body, making it possible to drain and test the valve safely and quickly.

Inner float assemblies

Inner floats are made of bar stock polypropylene, which ensures they never change shape or mass over time. The four guide ribs on the valve body ensure that the floats are all guided squarely to the body, ensuring they do not become offset to the side.

FAQ

 

Q: What is automatic air release valve?

A: During the working process of the air release valve, it is the pressure of the gas that controls the opening and closing of the air release valve, without manual operation. This is why air release valves are also called automatic air release valves.

Q: Do air release valves leak water?

A: When the air release valve exhausts from the exhaust hole, it will leak water. The amount of leak water depends on the sealing performance of the air release valve.

Q: What is an air release valve?

A: An air release valve is typically used in water or irrigation schemes to ensure that any entrained air in the water system is automatically released in order to maximize the system performance.

Q: What is the difference between air release valve and air relief valve?

A: Furthermore, a relief valve won't vent accumulated air at pressures below the set point. Unlike a pressure relief valve, an air release valve is open at atmospheric pressure, then closes automatically when liquid is present.

Q: Do I need an air release valve?

A: As a rule of thumb, air release valves and air vacuum valves should be installed every 800m on long pipe runs to properly vent and draw air into the system. When valves are suddenly shut off, vacuums can form downstream from the valve due to the momentum of the flow.

Q: How to test an air release valve?

A: With the inlet shutoff valve open, partially open the drain valve until flow can be heard. If the air valve is working properly, water should be exhausted from the drain valve.

Q: Where are air relief valves provided at?

A: Due to the accumulation of air, a backward pressure is created which causes a blockage to the flow of water. Thus, air valves are provided at the summit of the pipe to get rid of this accumulated air.
