An air valve control is a device used to regulate the flow of air in a system. It is typically used in air-conditioning, ventilation, and heating systems to regulate the air pressure and temperature. Air valve controls are also used in industrial applications, such as controlling the flow of air in a pneumatic system. The air valve control is typically composed of a valve body, a diaphragm, and a control knob. The valve body is connected to the system’s air supply, and the diaphragm is connected to the control knob. When the knob is turned, the diaphragm is pushed or pulled, which in turn opens or closes the valve. This allows the user to adjust the flow of air in the system. Air valve controls are essential for maintaining a comfortable environment in any building, as they help to regulate the air pressure and temperature. They are also important for industrial applications, as they help to control the flow of air in a pneumatic system.
