Honeywell 14004242-001 Operator Assembly

The Honeywell 14004242-001 is a high-performance Top Mount Operator Assembly engineered specifically for integration with MP918A and MP918B Series Damper Actuators. This critical pneumatic actuator accessory provides the mechanical interface necessary for driving medium-to-large-size dampers in demanding commercial HVAC environments. As a professional-grade replacement operator assembly, it ensures the precise translation of pneumatic force into rotational or linear movement required for accurate airflow control and proportional damper positioning.

Designed for field durability, this assembly features low-friction tolerances to maintain the operational efficiency of the rolling diaphragm piston-type actuators it supports. For technicians managing commercial HVAC systems, the 14004242-001 serves as a reliable top-mount shaft adapter and linkage component, securing a robust connection between the actuator shaft and the 5/16-inch pushrod. Its construction is optimized to handle the high actuator force typical of the MP918 series, supporting system stability even under varying load conditions without the risk of mechanical slippage.

• Precise Actuator Alignment: Specifically machined for top-mount installation on Honeywell MP918 series pneumatic actuators to ensure zero-offset linkage.
• Heavy-Duty Mechanical Linkage: Facilitates a secure connection to 5/16-inch pushrods, essential for driving large damper blades in industrial air handlers.
• Field Reliability: Built with high-tolerance components that reduce wear on the actuator shaft and maintain proportional control accuracy.
• Direct OEM Compatibility: Serves as the factory-spec Honeywell 14004242-001 replacement part, eliminating the need for improper field modifications.

Which actuators are compatible with the 14004242-001 assembly?
This operator assembly is specifically designed for use with Honeywell MP918A and MP918B series pneumatic damper actuators.

What is the standard pushrod size for this operator?
The assembly is engineered to adapt the actuator shaft to a standard 5/16-inch pushrod for robust mechanical transmission.

Can this be used for both normal and smoke-rated dampers?
Yes, provided it is paired with the appropriate MP918 series actuator model rated for those applications, as it maintains the required stroke and force tolerances.
