What is an air valve?

An air valve, also known as an air control valve or an air release valve, is a mechanical device used to regulate the flow of air within a system. It is commonly employed in various industries to control the release, intake, or exhaust of air, ensuring proper pressure and flow management. They can be manually operated or automated, depending on the application and requirements. In pneumatic systems, they play a crucial role in controlling the movement of air cylinders, actuating pneumatic actuators, and managing the flow of compressed air. Overall, they are essential components in various industries, providing reliable and efficient control over the flow of air within systems to ensure optimal performance.

Types:

Single Orifice: Features a single opening for air intake or release, providing precise control over airflow.

• Double Orifice: Has two separate openings for air intake and release, offering flexibility in airflow control and pressure management.
• Double Orifice Kinetic: Utilizes kinetic energy for efficient air release, with two openings and enhanced performance for high-flow applications.

Function:

Release of Air: Air valves allow for the controlled release of air from a system, preventing airlock and maintaining optimal performance.

• Intake of Air: They facilitate the intake of air into the system when necessary, ensuring proper ventilation and pressure regulation.
• Pressure Relief: Help relieve excess pressure buildup within the system, preventing damage to components and ensuring safe operation.
• Preventing Backflow: In pneumatic systems, prevent the backflow of air, maintaining the desired direction of airflow and system functionality.
• Priming: These valves assist in priming systems by ensuring the proper evacuation of air pockets, allowing for efficient operation.

Why and where should we install them?

• They are typically installed at specific locations within a pneumatic system to ensure optimal performance and functionality. Here are common locations and reasons for installing air valves:
• High Points: These are often installed at high points in the system to release trapped air and prevent airlock. This ensures efficient operation by allowing the system to maintain proper pressure and flow.
• End of Lines: Installing air valves at the end of lines helps to purge air from the system during startup or after maintenance, ensuring that the system is properly primed and ready for operation.
• Critical Points: These valves may be installed at critical points in the system where air accumulation is likely to occur, such as bends, elbows, or changes in elevation. This helps to prevent air buildup and maintain system efficiency.
• Water Hammer Prevention: In water systems, they are installed at high points to release air pockets and prevent water hammering, which can cause damage to pipes and fittings due to sudden pressure surges.
• Pump Intake: These valves may be installed at pump intakes to prevent air from being drawn into the pump, which can cause cavitation and damage to the pump.

Overall, the installation of air valves at strategic locations within a pneumatic system helps to ensure proper operation, prevent damage, and maintain system efficiency.
