Sporlan 180399P Power Element
The Sporlan 180399P (KT-46-SZ) is a replacement thermostatic power element designed for field servicing of Sporlan thermostatic expansion valves. This Type 46 element features a 60-inch capillary tube and is engineered for precise refrigerant metering in specialized R-404A and R-507 applications. Given the SZ charge characteristics, this element is optimized for sub-zero temperature ranges, ensuring consistent superheat control and preventing compressor floodback during low-evaporator temperature operations. The stainless steel diaphragm provides the necessary durability to withstand pressure fluctuations and corrosive environments typical in commercial refrigeration racks and walk-in freezers.
When performing a TXV power element replacement, the KT-46-SZ offers a direct fit for Sporlan "S" and "M" body valves, maintaining the integrity of the original refrigeration system design. Proper installation requires ensuring the sensing bulb is securely strapped to a clean, horizontal section of the suction line. This HVAC mechanical part is critical for technicians troubleshooting refrigeration expansion valve failure where the original element has lost its charge or suffered capillary fatigue. Utilizing this genuine Sporlan replacement part ensures the valve responds accurately to load changes, maximizing system efficiency and protecting the compressor.
Key Benefits for Technicians- System Compatibility: Specifically calibrated for R-404A and R-507 systems with sub-zero (SZ) temperature requirements.
- Extended Capillary: The 60-inch capillary length provides flexibility for bulb placement in complex piping configurations.
- Reliable Superheat Control: Precision-engineered diaphragm ensures stable refrigerant flow under varying thermal loads.
- Durable Construction: High-grade materials resist fatigue and environmental stress, reducing the frequency of call-backs.
What are the symptoms of a failed power element?
A failed element typically results in the TXV remaining closed or restricted, causing low suction pressure and high superheat. If the capillary is broken, the valve will not open regardless of temperature changes.
Can I use a KT-46-SZ on an R-22 system?
No. The KT-46-SZ is charged specifically for R-404A/R-507. Using it with R-22 will result in incorrect pressure-temperature relationships and poor superheat control.
How do I verify if the element charge is still intact?
Check for resistance when pressing on the internal diaphragm. If the diaphragm is slack or can be depressed easily by hand with no spring-back, the power element has likely lost its thermostatic charge.
