Johnson Controls SET29A-624R Sensing Element

The Johnson Controls SET29A-624R Sensing Element is a critical replacement component engineered specifically for 1/2" Johnson Controls V47 Series temperature-actuated modulating valves. Built for high-demand HVACR environments, this sensing element kit provides the thermal responsiveness required to maintain precise setpoints in industrial and commercial refrigeration systems. Designed as a direct OEM replacement part, it ensures 1/2-inch valve compatibility without the need for extensive field modifications, allowing for rapid restoration of seasonal system efficiency.

This Johnson Controls sensing element is calibrated for specialized temperature ranges, typically supporting 115°F to 180°F applications. It effectively translates ambient or fluid temperature changes into mechanical force, modulating water or refrigerant flow to stabilize condenser pressures. For technicians troubleshooting V47 valve maintenance or inconsistent cooling cycles, installing a SET29A-624R is the professional standard for ensuring long-term reliability and accurate thermal feedback within the control loop.

Common Questions

Is the SET29A-624R compatible with larger V47 series valves?
No, this specific sensing element is sized and calibrated exclusively for 1/2" valves. Using it on larger bodies will result in improper seating and inaccurate modulation.

What is the standard bulb size for this replacement kit?
This kit typically features a standard sensing bulb and capillary length designed for Johnson Controls water valves, usually measuring approximately 11/16" x 3-1/4".

Can this element be field-installed without removing the valve body?
Yes, the SET29A-624R is designed for top-entry replacement, allowing technicians to service the 1/2" modulating valve without breaking the main piping connections.
