Use

These actuators are designed for use in constant or variable air volume installations for the control of return air, mixed air, exhaust, and face and bypass dampers requiring up to 160 lb-in (18 Nm) torque. They are designed for applications that require the damper to return to a fail-safe position when there is a power failure.
