Honeywell 43196000-038 Temperature Kit

The Honeywell 43196000-038 High Temperature Kit is a critical accessory for Honeywell ML6421B and Honeywell ML7421B linear actuators requiring enhanced thermal protection. Engineered specifically for actuators with 1 1/2" stroke (38 mm), this field-installable kit acts as a thermal barrier, increasing the maximum operating fluid temperature to 428 degrees Fahrenheit (220°C). This makes it essential for high-pressure steam and hot water applications where standard valve actuators would otherwise exceed their ambient or process temperature limits. As a veteran technician, you know that keeping the gear within spec is the only way to prevent premature failure. This kit provides the necessary actuator heat protection and high temperature valve kit performance needed for demanding hydronic and steam systems. Note that this component is not compatible with Q5022B linkages, so verify your hardware before heading to the job site. The stem button attachment ensures a precise mechanical connection for reliable HVAC valve linkage operation under extreme conditions.

• Extends process temperature limits up to 428°F, enabling safe use in high-pressure steam applications.
• Designed for a perfect fit on Honeywell ML6421B and ML7421B actuators with a 38 mm stroke.
• Provides a robust thermal spacer to protect internal actuator electronics and motor components from excessive heat.
• Ensures actuator compatibility with high-performance globe valves in commercial HVAC environments.
• Simplifies field upgrades without needing to replace the entire valve actuator assembly.

Can I use this kit on the ML7421A version?
No, the -038 kit is specifically sized for the 1 1/2" (38 mm) stroke found on "B" models. For the 3/4" (20 mm) stroke "A" models, you must use the 43196000-001 variant.

What is the maximum fluid temperature after installation?
Once properly installed on the compatible valve and actuator, the assembly can handle media temperatures up to 428°F (220°C).

Is this compatible with the Q5022B linkage?
This kit is not compatible with Q5022B. Always check your specific linkage and valve body pairing to ensure the 1.5-inch stroke path is clear and compatible.
