Heavy Duty Electric Actuator With Direct Coupling, 210 In-Lb Running Torque, Four Control Inputs, Position Feedback For Closed-Loop Control, Versatile, -4 To 122 F Operating Range
The M91xx Series direct-mount electric actuators are designed for damper and valve control in HVAC and industrial systems. They operate on AC/DC 24 V power, offer four control inputs, and provide output position feedback for simple closed-loop control. The rotation is mechanically adjustable from 0 to 90 degrees in 5-degree steps, with integral auxiliary switches available to indicate end-stop position. The housing is NPT threaded to fit electrical fittings, and shafts up to 3/4 in (20 mm) round or 5/8 in (16 mm) square are supported.

💡 What is a direct-coupled heavy-duty electric actuator used for in HVAC dampers and valves, and how does position feedback help with closed-loop control?
In HVAC and industrial control, this actuator provides reliable, direct drive to dampers or valves and uses feedback to ensure accurate positioning.
- Direct mounting to damper or valve shaft simplifies installation and reduces linkage loss
- Output position feedback enables precise end-stop sensing and repeatable positioning
- Multiple input types allow easy integration with standard controllers
- Rugged NPT threaded housing suits field connections
