Satchwell AET/AEST Controller-Actuator Data Sheet

This data sheet describes the Satchwell AET and AEST controller-actuators, which provide proportional control of valves or dampers for heating, cooling, and air conditioning systems using temperature detectors or 135 ohm potentiometric input devices. The AEST model includes a power failure return feature with a battery-powered DC motor, while both models offer selectable stroke angles, torque specifications, and linkage kits for various valve and damper applications.
