Honeywell 14004139-001 Retrofit Kit

The Honeywell 14004139-001 is a professional-grade Positive Positioner Retrofit Kit designed specifically for field-converting MP953A pneumatic actuators to the high-performance MP953E series. Engineered for 8-inch and 13-inch diameter actuators, this kit is essential for contractors looking to improve proportional control and eliminate hysteresis in existing HVAC pneumatic systems. This heavy-duty assembly includes the 14004211-001 feedback spring kit, a high-tolerance O-ring, and the internal positioner components required to maintain a consistent 3/4-inch stroke. By upgrading to a positive positioner, you ensure the valve stem reaches the exact position dictated by the controller, regardless of friction or varying line pressures. This direct-acting kit (identical to the 14004139-001/U) is built for modernizing steam and chilled water valve assemblies including V5011 and V5013 models. Its rugged construction supports a maximum safe operating pressure of 25 psi and is rated for ambient temperatures between 0°F and 140°F, making it a reliable solution for demanding commercial mechanical rooms.

• Precise Actuator Response: Integrates a positive positioning relay to ensure exact 3/4-inch travel for superior flow modulation.
• Simplified Field Upgrade: Converts MP953A to MP953E models without needing to replace the entire actuator housing.
• Complete Retrofit Package: Includes the 14004211-001 feedback spring kit and necessary O-rings for a leak-free seal.
• Broad Compatibility: Validated for use with 8" and 13" Honeywell pneumatic actuators used in high-volume air handling and central plant applications.
• System Efficiency: Reduces hunting and improves the lifecycle of rolling diaphragms by providing stabilized control signals.

Is the 14004139-001 compatible with reverse-acting actuators?
No, this specific kit is engineered for direct-acting MP953A and E series units. For reverse-acting MP953B or F models, you would typically require the 14004138-001 retrofit kit.

What diaphragm sizes does this positioner kit support?
This kit is specifically sized for the larger 8-inch and 13-inch Honeywell pneumatic actuators. It is not intended for the 5-inch versions, which require different spring calibrations.

Does this kit include the feedback spring?
Yes, the assembly includes the 14004211-001 feedback spring kit, which is critical for providing the mechanical counter-force required for accurate position sensing.
