Sporlan 180402P Power Element

The Sporlan 180402P Power Element, also identified as the KT-46-VX100, is a critical replacement component for thermostatic expansion valves (TEV) utilized in diverse refrigeration and HVAC environments. Engineered with a large flat stainless steel diaphragm, this power head ensures precise superheat control and consistent refrigerant metering across varying load conditions. It features a 60-inch capillary tube length and is optimized for systems utilizing R-22, R-407C, or R-422D refrigerants. The "VX100" designation indicates a 100 PSI Maximum Operating Pressure (MOP) charge, making it ideal for air conditioning and heat pump applications where motor protection against overloading is required during high-pressure pull-down periods. As a veteran-grade Sporlan replacement part, it offers a durable, welded construction that prevents leak paths and maintains factory-set calibration throughout the equipment's operational life. This element is compatible with Sporlan valve bodies including the Type EG series, providing a high-integrity refrigeration valve component solution for field technicians seeking to restore system equilibrium and evaporator efficiency.

• Precise Superheat Regulation: The large diaphragm surface area delivers high sensitivity to pressure changes for tighter evaporator control.
• Engineered MOP Protection: The 100 PSI pressure limit charge prevents compressor motor overload by restricting suction pressure during startup.
• Durable Construction: Features a corrosion-resistant stainless steel diaphragm and welded element for long-term hermetic integrity.
• Extended Reach: Equipped with a 5-foot capillary tube to accommodate flexible sensing bulb placement on the suction line.
• Multi-Refrigerant Compatibility: Works effectively with R-22, R-407C, and R-422D systems, reducing truck stock requirements for contractors.

Is the KT-46-VX100 compatible with R-410A systems?
No, this power element is designed for R-22 and compatible replacements like R-407C. R-410A systems require high-pressure elements specifically rated for that refrigerant's operating envelope.

Does this element include the sensing bulb strap and insulation?
This SKU typically covers the power head and capillary assembly. It is standard practice to reuse or replace the bulb clamps and specialized thermal insulation to ensure accurate temperature sensing at the suction line.

How do I know if my current power element has failed?
Loss of charge in the element usually results in the TEV remaining closed or restricted, causing low suction pressure and high superheat. If the diaphragm is "flat" or lacks tension, replacement of the power head is necessary.
