Dźwignia Honeywell „221455A”
This is a Honeywell 221455A lever, listed under actuator components. Parts of this type are used within the actuator assembly that positions air dampers or mixing valves in burner and heating systems. A lever of this kind typically serves as a mechanical link between the actuator motor and the driven component, or as a manual override handle that allows the engineer to move the damper or valve when the actuator is not powered. It may also be part of the coupling that connects the actuator shaft to the damper or valve spindle. When replacing such a lever, the critical factor is matching the mechanical interface—the bore diameter, keyway or flat pattern, and overall length—to both the actuator output shaft and the driven spindle. The lever must engage securely without play to avoid erratic positioning or stripped connections. Check the original part for signs of deformation, cracking, or corrosion, especially if the actuator has been exposed to heat or moisture. Also verify that any retaining screws or pins are still serviceable. Since levers are often specific to a given actuator series, confirm the Honeywell actuator model and the lever’s intended function (e.g., manual release, coupling, or position indicator) before ordering.
