상품 소개

The motorized shut-off damper inserts a single circular blade into a short galvanized duct body. A direct-mounted actuator rotates the shaft through approximately ninety degrees to isolate or restore airflow. A perimeter blade seal reduces closed leakage, and the shaft mark provides a mechanical position reference visible outside the duct. Spring-return actuator versions move to the specified open or closed position when power or control pressure is lost, while auxiliary switches can confirm the endpoints.

주요 기능

A short round casing fits isolation points where a multiblade rectangular frame would require excessive space.

The single blade and direct shaft connection provide a simple open-close movement with few linkage components.

A compressible perimeter seal restricts leakage around the circular blade in the commanded closed position.

Spring-return and end-switch options support fail-position sequences and remote proof of isolation.

고객 제품 관심사

Reliable shut-off requires the correct fail position, enough actuator torque for seal compression and access to the drive after insulation and ceiling closure.

A modulating damper is used for isolation but never reaches a repeatable sealed endpoint.Defined open-close end stops and a matched actuator focus the mechanism on dependable shut-off travel.

Loss of control power leaves the process branch open.A spring-return actuator moves the blade to the selected normally closed safety position.

Duct insulation hides the shaft mark and actuator release.An extended mounting bracket keeps position indication, wiring and manual override outside the insulation layer.

Excessive differential pressure twists the shaft before the seal seats.Blade diameter, shaft size and actuator torque are selected together for the maximum closed pressure.
