Honeywell 14004210-001 Spring Kit

The Honeywell 14004210-001 Feedback Spring Kit is an essential component for technicians calibrating pneumatic damper actuators in the field. This versatile range conversion spring kit is specifically engineered for use with Honeywell MP909H and MP918A series actuators, providing the precise mechanical feedback required for proportional control. By selecting the appropriate spring from this kit, contractors can adjust the operating range and span of the actuator to match the specific requirements of HVAC mixing boxes or variable-volume terminal units.

Built for durability in demanding environments, the 14004210-001 kit includes three distinct springs?3 psi, 5 psi, and 10 psi?color-coded for rapid identification during installation. These high-tension springs allow for the conversion of standard pneumatic actuators into high-performance units with adjustable start points, ensuring accurate damper positioning and optimal airflow management. Whether performing a positioner retrofit or replacing worn internal components, this OEM-grade kit ensures your pneumatic control system maintains peak efficiency without erratic cycling or signal lag.

• Multi-Span Compatibility: Includes 3 psi, 5 psi, and 10 psi springs to satisfy diverse HVAC control sequences.
• Direct OEM Replacement: Guaranteed fit for Honeywell MP909H, MP918A, and MP904 series pneumatic operators.
• Enhanced Proportional Control: Facilitates precise feedback signaling for smoother damper modulation and energy savings.
• Simplified Calibration: Designed for easy field swapping, allowing technicians to adjust actuator span in minutes.

Which actuators are compatible with the 14004210-001 spring kit?
This kit is designed for use with Honeywell MP904, MP909H, and MP918A series pneumatic damper actuators featuring positive positioners.

How do I identify the different pressure ratings in the kit?
The springs are typically color-coded (orange for 3 psi, yellow for 5 psi, and blue for 10 psi) to ensure the correct span is applied to the positioner feedback loop.

Can this kit be used to convert an MP909E to an MP909H?
Yes, when used in conjunction with a positive positioner retrofit kit, these springs allow for the conversion of E-series models to high-precision H-series functionality.
