Dayton MP-460VT HVAC Control Actuator

HVAC Control Actuator for Damper Systems

The Dayton MP-460VT actuator operates dampers and valves in commercial heating, ventilation and air-conditioning installations. It mounts directly to compatible damper shafts and provides proportional control for airflow regulation. Facility managers and HVAC contractors use it to automate zone control in office buildings, schools and hospitals.

Compatible with Multiple Damper Models

This actuator fits Grainger items 2FTW4, 3TZ50 and the 4HX series from 64 through 71. It also matches the 3HHL, 2FTW, 2FTX, 2FTU, 2FTV, 3HHN, 6WRK and 5NKN series listed in the specifications. Installers should verify the damper model number before ordering to ensure proper shaft engagement and torque delivery.

Direct Replacement for Worn Actuators

The unit replaces failed or ageing actuators on the listed Grainger damper assemblies without bracket modifications. Swapping the old unit restores modulating control and eliminates hunting or stuck damper blades. The upgrade is worthwhile when existing actuators no longer hold position or respond erratically to control signals.
