Air compressor valves are valves that control the flow and pressure of liquids, gases, and slurries within a system. They are also known as regulators and are used in a wide variety of applications. For all types of media that are conveyed through pipes, there must be valves to control their flow. 
They operate based on pressure difference: if the pressure below the valve is greater than the pressure above plus the spring force, it opens. 
It is vitally important to select a valve that will provide the most satisfactory performance, long valve life, and least amount of maintenance.
