It allows airflow in a single direction while blocking reverse flow, protecting the system from pressure loss and backflow contamination. The valve body is brass with a straight-through design, 1/2-inch NPT female inlet and male outlet ports, and comes with pre-applied thread sealant. It is typically replaced when it fails to seal, causing air pressure drops or abnormal brake behavior.
