    摘要: A multipurpose valve tool is provided. The multipurpose valve tool includes multiple flow control discs, a retention ring, and a valve key. The flow control discs are configured to be installed within a valve body of a valve assembly to modulate a flow of fluid through an outlet port of the valve body. The retention ring is configured to retain the flow control discs on a component of the valve assembly when the flow control discs are not installed within the valve body. The valve key includes a first end configured to engage an installation feature in a retention fastener for one of the flow control discs. The flow control discs, the retention ring, and the valve key are detachably coupled to each other.

    摘要: A fire damper actuation system in an HVAC system includes a damper system and an actuator system. The damper system includes damper blades rotatable between an open configuration and a closed configuration, a crank arm assembly configured to drive the damper blades, a spring assembly configured to be held in a loaded condition when the damper blades are in the open configuration, a temperature-activated fusible link, and a fusible link arm coupling the temperature-activated fusible link to the crank arm assembly. The actuator system includes a motor and a drive device. The drive device is coupled to the crank arm assembly and the temperature-activated fusible link. Operation of the drive device by the motor between a first end stop location and a second end stop location simultaneously rotates the crank arm assembly and the temperature-activated fusible link to complete a test inspection procedure.
