Product Introduction

The larger gear housing and shaft coupling address dampers whose resistance exceeds the smaller actuator class. A floating three-point command drives the motor in either direction and stops it at the commanded position.

Key Features

The larger torque output suits mechanically demanding blade banks.
A manual release assists alignment during shaft installation.

Solutions for Your Application

A small actuator cannot overcome the damper operating torque.

The 40 Nm output provides a higher torque class for the mechanical load.

The controller provides directional contacts rather than an analog signal.

Floating three-point operation accepts separate opening and closing commands.

Available Options

Jackshaft linkage
Shaft extensions
Mounting brackets
