Non return valve / check valve
This valve ensures that when the compressor unloads or stops generating
air, it retains the pressure in the downstream system.
About the part
A non-return valve (NRV) or check valve is a mechanical device that allows fluid to flow in one direction only. They are also known as reflux valves, retention valves, foot valves, or one-way valves. Check valves have two openings, one for fluid to enter and one for it to leave. They are flow sensitive and open when the upstream pressure is greater than the seat release pressure
