Johnson Controls SET29A-630R Sensing Element

As a seasoned technician, you know that maintaining precise temperature regulation in HVAC and industrial systems requires reliable hardware. The Johnson Controls SET29A-630R is a high-performance replacement sensing element specifically engineered for V47 series temperature actuated modulating valves. This Penn sensing element is designed for heating applications, featuring a calibration range of 160 to 230°F (71 to 110°C). When your existing 1-1/2 inch modulating valve loses its responsiveness, swapping in this heavy-duty temperature probe is far more cost-effective than a total valve assembly replacement.

The unit features a cross-ambient sensing capability and a durable 11/16 x 16-1/4 inch bulb, ensuring accurate thermal feedback even in demanding environments. Built with a nylon-armored capillary for physical protection, the SET29A-630R sensing element ensures your fluid or air control systems maintain stable operating setpoints. Whether you are servicing a boiler system or an industrial process loop, this Johnson Controls replacement part provides the exact OEM specifications needed to restore factory-level performance and prevent system drift.

• Precise Modulation: Specifically calibrated for heating cycles with an opening point range of 160 to 230°F.
• OEM Compatibility: Direct drop-in replacement for 1-1/2" V47 series temperature-actuated valves.
• Industrial Durability: Includes a high-grade sensing bulb and protected capillary for long-term field reliability.
• Field Serviceable: Allows for rapid restoration of valve function without removing the valve body from the piping.

• What valve sizes is the SET29A-630R compatible with? This element is standard for 1-1/2 inch V47 series modulating valves designated for high-temperature heating.
• Can this be used for cooling applications? No, this specific model is calibrated for 160-230°F heating cycles; for cooling or lower ranges, a different SET29 series element is required.
• Is the bulb well included? No, as is standard for replacement sensing elements, the well must be ordered separately if the original is damaged.
