Quick Release Valve / Schnellentlüftungsventil 4-4704

Description

Quick release valves vent the brake chambers straight to atmosphere instead of returning the air along the line to the brake valve. The shorter exhaust path releases the brakes faster, which matters most on long-wheelbase vehicles and trailers.

It cross-refers to the original equipment numbers 973 500 017 0.
