Industrial 800840RT Brake Control Module Recessed Plate

Rig Tough 800840RT MV-3 Dash Valve with a recessed mounting plate is a compact brake-control valve designed for dash-mount installations in heavy‑duty trucks. Identified as 800840RT (often listed with the internal code R62), this unit represents the recessed‑plate variant of the MV‑3 dash valve family, built to integrate into dashboard cavities with a flush, low-profile profile. The recessed plate uses M6 x 1 threaded mounting holes (6H) for secure attachment to compatible dash panels, enabling reliable operation in demanding commercial-vehicle environments. As part of the MV‑3 lineage, it serves as a manual control element within air-brake systems, allowing the operator to influence brake application in a compact, dashboard-mounted form factor. This makes it well-suited for installations where space is at a premium or where a clean, integrated appearance is required on the vehicle’s control console. Typical applications include medium- and heavy-duty tractor-trailer configurations and other commercial trucks that utilize Bendix MV‑3–style dash valves, where a recessed-plate mounting approach is specified. When selecting this part, verify that the mounting hole pattern and thread size match your dash plate (M6 x 1, 6H) and confirm that the MV‑3 recessed-plate configuration aligns with your vehicle’s installation requirements.
