Sporlan 180338 KT-43-PC Element

The Sporlan 180338 KT-43-PC Element is a critical replacement component for thermostatic expansion valves (TXV) in commercial refrigeration systems. Engineered specifically for R507C refrigerant and compatible with the R404A family, this Power Element features a 5-foot (60-inch) capillary tube, allowing for flexible bulb placement on the suction line. The KT-43-PC utilizes a "C" charge, optimized for low-temperature applications ranging from -10°F to -40°F. The stainless steel diaphragm and welded construction ensure long-term hermetic integrity, preventing refrigerant leaks and maintaining precise superheat control. As a veteran-preferred part, it is designed for seamless integration with Sporlan F, E, BF, and SBF valve bodies. Replacing a failed KT-43-PC power head allows for efficient system restoration without the need to un-sweat the entire valve body, significantly reducing labor time on the job site. This genuine OEM element is built to handle the high head pressures and demands of modern refrigeration cycles.

• Optimized Low-Temp Performance: The "C" charge provides stable operation for low-temperature evaporators and R507C refrigeration systems.
• Precision Superheat Control: The large flat diaphragm design ensures fine-tuned refrigerant flow to prevent liquid slugging.
• Application Flexibility: A 60-inch capillary tube provides ample reach for proper sensing bulb positioning on various evaporator configurations.
• Durable Construction: High-grade stainless steel fabrication prevents corrosion and maintains charge pressure in demanding environments.
• Service Efficiency: Field-replaceable design allows for rapid maintenance on thermostatic expansion valves without reclaiming the full charge in some valve configurations.

Is the KT-43-PC compatible with other refrigerants?
While optimized for R507C, this element is also frequently utilized in R404A systems due to the similar pressure-temperature relationship of these refrigerants.

How do I identify if the element has failed?
A lost power element charge typically results in a restricted valve, leading to high superheat, low suction pressure, and potentially an iced-up evaporator coil.

Does this fit all Sporlan valves?
This is a Type 43 element. It fits specific small-body valves including the F, E, BF, SBF, Q, and SQ series. Always verify the element size number stamped on the existing power head before replacement.
