The Alltrux ATX21897 Dash Control Valve replaces OEM 800260 and is designed as an MV-3™ style air brake control valve used in heavy-duty truck air systems.

This dash-mounted push-pull valve controls air delivery to the parking brake and trailer air supply circuits. It allows the operator to apply or release spring brakes and manage tractor protection functions within the vehicle’s air brake system.

Built for commercial truck applications, the ATX21897 is engineered to meet OEM performance standards for durability and reliable air system control. It is commonly used in tractors equipped with spring brake systems requiring MV-3 style dash control functionality.

Always verify plumbing configuration and port compatibility before installation.
