Johnson Controls SET29A-626R Sensing Element

The Johnson Controls SET29A-626R is a high-precision replacement sensing element designed specifically for integration with 3/4" water modulating valves, such as the V47AC series. Engineered for heavy-duty HVAC and industrial refrigeration applications, this element features a heating bulb configuration with a control range of 115 to 180°F. As a veteran-grade modulating valve part, it ensures accurate temperature sensing and fluid flow regulation in systems where maintaining tight setpoints is critical for compressor efficiency and head pressure control. The rugged construction is optimized for sensing element replacement in existing valve bodies, offering a seamless mechanical fit without requiring extensive piping modifications. By utilizing a Johnson Controls temperature sensor element that responds rapidly to thermal changes, contractors can prevent water hammer and ensure smooth modulation across the entire V47 series valve stroke. This component is essential for technicians performing field repairs on temperature-actuated valves that have lost their charge or suffered capillary damage.

• Optimized Compatibility: Purpose-built for 3/4" Johnson Controls valves, ensuring precise physical alignment and reliable stroke performance.
• Wide Thermal Range: Operates efficiently within a 115 to 180°F range, ideal for heating applications and high-setpoint industrial processes.
• Industrial Durability: Designed to withstand the thermal stress of modulating water systems, reducing frequency of maintenance cycles.
• Rapid Technical Response: The high-sensitivity thermal bulb provides immediate feedback to the bellows, maintaining stable discharge temperatures.

• What valves are compatible with the SET29A-626R? This element is specifically designed for 3/4" V47 series modulating valves, particularly models like the V47AC-4C and V47AC-6C.
• Can this element be used in cooling applications below 115°F? No, this is a heating bulb element calibrated for the 115-180°F range. For lower temperature or cross-ambient needs, a different sensing bulb style is required.
• How do I ensure the bulb is installed correctly for optimal sensing? For the most accurate modulation, the capillary end of the bulb should be positioned higher than the plugged end to ensure proper volatile charge distribution.
