Air Dash Tract Trailer Valve

Dash Air Valve (Part #150413), commonly used on Capacity yard trucks and industrial terminal tractors for controlling air routing between the tractor (dash) and trailer circuits. It’s a key pneumatic component in the brake/air system that helps manage air flow for safe trailer braking and tractor air functions. When this valve wears or fails, you can experience improper air distribution. This leads to trailer braking issues, air leaks, or poor system responsiveness
