Wabco 4340140000 is a check valve, a genuine Wabco part from Pro Gear and Transmission.
A check valve of this kind lets compressed air pass in one direction and closes to stop it flowing back, which helps hold pressure in the tanks and lines it protects. The valve is spring loaded: pressure from the inlet side opens it, and it seats again when outlet pressure plus the spring force beats the inlet pressure.
