상품 소개

The HVAC damper actuator combines a reversible electric motor, reduction gear train, position electronics and universal shaft clamp in one sealed housing. It mounts directly on a round or square damper shaft, with an anti-rotation bracket preventing the body from turning. Adjustable stops limit the travel angle, while a manual release allows the blade position to be set during installation. Non-spring and spring-return versions support ordinary modulation, shut-off and selected safety-position duties.

주요 기능

A universal clamp accepts common round and square shafts without a separate crank linkage.

Mechanical end stops define the usable rotation range and protect the damper linkage from overtravel.

Manual override disengages the gear train for blade positioning during installation or service.

Control variants cover two-position, three-point floating and proportional analog operation with optional feedback.

고객 제품 관심사

Actuator reliability depends on correct torque, shaft geometry, travel direction, supply voltage and a fail-position strategy matched to the controlled damper.

The actuator reaches full torque but the damper still leaks because the blade bank needs more closing force.Required torque is calculated from blade area, differential pressure, seal drag and linkage efficiency before selecting the drive.

A loose shaft clamp slips after repeated reversals.A correctly sized self-centering clamp and anti-rotation bracket secure both the shaft and actuator housing.

The control signal opens the damper when the sequence expects closure.Selectable rotation direction and clearly set end stops align actuator travel with the blade position indication.

Loss of power leaves an isolation damper in an uncontrolled intermediate position.A spring-return model drives the shaft to the specified safety endpoint without relying on the controller.
