Product Description
The Bendix K021464 MV-3 Dash Control Valve is a heavy-duty pneumatic control assembly designed for select Volvo, Mack, and International commercial trucks equipped with air brake systems. This multifunction dashboard valve combines tractor parking brake control, trailer air supply control, and dual-circuit air supply protection into a single compact assembly.
Featuring two push-pull control buttons, the MV-3 allows drivers to operate the tractor parking brakes and trailer air supply independently. Its integrated dual-circuit supply valve helps maintain the required air pressure for proper parking brake operation, while automatic pressure-sensitive functions provide protection when system pressure drops below specified limits.
The K021464 features integrated push-to-connect fittings that simplify installation and reduce the need for separate adapters. Its durable construction is designed for demanding commercial vehicle operating conditions, making it an excellent replacement for a damaged, leaking, or malfunctioning dashboard brake control valve.
