Dayton MP-208VT Actuator

The Dayton MP-208VT is an HVAC actuator designed for damper and valve control in commercial building systems. It suits facilities engineers and maintenance technicians who need a direct replacement for worn or failed units on compatible air-handling equipment.

Replaces Grainger items 2FTV1

This actuator replaces a wide range of Grainger-listed part numbers including 4HX64 to 4HX71 and 5NKN7 to 6WRK9. The jump is worth it when the existing actuator shows drift, noise or complete loss of position control on the same mounting pattern.

Mounts on existing bracket with standard wiring

Installation uses the original mounting bracket and wiring terminals, so no new holes or adapters are required. The most common issue is mismatched shaft coupling or incorrect voltage selection, which prevents the actuator from stroking fully.

Questions about this item

Which Grainger items does the MP-208VT actuator mount to?

It fits Grainger items 2FTV1, 3TZ50, 4HX64 through 4HX71, 3HHL4 through 3HHL9, 3HHN1 through 3HHN3, 2FTW8, 2FTU9, 2FTV7, 2FTX4, 2FTX5, 6WRK7 through 6WRK9, and 5NKN7 through 5NKN9.

How is the actuator installed and what step is often missed?

Mount it to the compatible damper or valve body, then wire the 208 V supply; the step often missed is verifying the shaft rotation direction before tightening the linkage.

What maintenance will the MP-208VT need over time?

Periodically inspect the shaft seal and linkage for wear, listen for abnormal motor noise, and replace the unit if the actuator no longer drives the damper through its full stroke.
