Installation Locations:
●At pump discharge outlets.
●At local high points along transmission and distribution pipelines.
●At elevated points immediately downstream of pipeline bends.
●It is recommended to install one air valve every 400–800 meters.
●The recommended air valve size is approximately 1/8 of the main pipeline diameter.
Functional Features:
●Rapid air release from the pipeline:
▶ Improves the operating efficiency of pumps and pipelines.
●Prevents air locking, water hammer, and unstable flow conditions.
Negative Pressure Protection:
●When negative pressure (vacuum) occurs inside the pipeline:
▶The air valve automatically admits air.
▶This prevents pipeline damage, deformation, or rupture.
Operating Principle of the Air Valve:

Operating Principle of the Air Valve:
Resilient Seated Gate Valve
The valve disc is rubber-coated and fits tightly with the valve seat, requiring low operating force and allowing easy installation and maintenance.
