Honeywell 14004264-001 Positioner Kit

The Honeywell 14004264-001 Positioner Kit is a field-installable pneumatic actuator accessory designed specifically for integration with MP918A Series Damper Actuators. This positive positioner kit ensures precise control of the actuator stroke in response to varying control signals, effectively overcoming damper linkage friction and high static pressure resistance. By establishing a definite relationship between the pneumatic control signal and the actuator’s mechanical position, this kit prevents actuator hunting and enhances the accuracy of air handling sequences. The bracket assembly provides a rigid mounting interface, maintaining alignment under heavy load conditions. As a direct Honeywell pneumatic replacement part, it is essential for multi-actuator configurations where synchronized operation is required. Utilizing a force-balance mechanism, the 14004264-001 allows for adjustable start points and operating spans, making it a critical component for technicians optimizing HVAC pneumatic control systems and ensuring reliable damper automation.

• Enhanced Positioning Accuracy: Eliminates hysteresis and ensures the MP918A actuator reaches the exact commanded position regardless of shifting load forces.
• Robust Build Quality: The heavy-duty bracket assembly manages mechanical stress in high-torque applications without flexing or losing calibration.
• Field Versatility: Supports adjustable pneumatic signal spans, allowing technicians to fine-tune the damper response to specific building automation requirements.
• Improved System Stability: Significantly reduces control loop oscillations by providing a stable mechanical feedback loop for the pneumatic pilot signal.

Is this positioner compatible with actuators other than the MP918A?
This specific kit is engineered for the MP918A series. Attempting to mount this assembly on different pneumatic cylinders may result in improper stroke alignment or mechanical failure.

Does the kit include the necessary feedback spring?
Yes, the 14004264-001 includes the positioner, mounting bracket, and standard feedback components required to convert a basic actuator into a positioned pneumatic drive.

Can the start point be adjusted for sequencing multiple dampers?
The internal mechanism allows for precise adjustment of the start pressure and operating range, facilitating sequence operation where one damper opens at a different PSI than another on the same branch line.
