bleed valve

Air purge port

A bleed valve is a valve that releases small amounts of fluid or gas from a pressurized system.

Mechanics open bleed valves to remove trapped air from brake lines or radiators: You'll need to open the bleed valve to get the air bubbles out.

In aviation and industrial settings, bleed valves regulate pressure by venting excess gas.
