How Does an Air Compressor Tank's Check Valve Work?

Tools are easily powered by an air compressor.

Air compressors serve workshops and home hobbyists with their powerful motors. Various parts comprise the air compressor, including the imperative check valve. Without this part, the compressor would not function.

Identification

An air compressor uses the surrounding air to fill its tank, and is subsequently pressurized. That pressurized air then pipes to power pneumatic tools, allowing the tools to work for a longer lifespan and be lighter in assembly.

Function

The check valve on an air compressor allows air inside the storage tank. As a one-way valve, the compressor's pump pulls air in through the check valve to become pressurized. The air that moves through the valve creates a back flow pressure against the check valve. As a result, this closes the valve and effectively seals it from leaking air.

Considerations

Over time, check valves can end up leaking. Before considering replacement, try cleaning it with soapy water to release any built up debris hindering the valve's functioning. If cleaning does not help, it will require replacement.
