Air Valves
An air valve is a valve used to control the flow of air. Air valves can also be used in various systems, such as in HVAC systems, where they are used to regulate the flow of air. The most common type of air valve is the check valve, which is a valve that allows air to flow in one direction only. Other types of air valves include relief valves, which relieve pressure from a system; control valves, which regulate air flow; and solenoid valves, which are electrically-operated valves.
