Sporlan 180941P Power Element

The Sporlan 180941P Power Element is a field-replaceable KT-83-FW/JW assembly designed for extreme-duty refrigerant flow management. For contractors dealing with erratic superheat or restricted flow, this thermostatic expansion valve element provides a reliable fix without requiring a full valve body replacement. Engineered for R-134a and R-12 systems, the KT-83-FW/JW utilizes a specific thermostatic charge tailored for medium to high-temperature applications ranging from 10°F to 60°F. The stainless steel diaphragm and welded construction are purpose-built to resist vibration and fatigue, maintaining precise pin-to-port alignment even in harsh commercial environments. With a 5-foot capillary tube length, this Sporlan power element replacement ensures flexible bulb mounting for optimal thermal contact on the suction line. Whether you are servicing a chiller, a reach-in cooler, or a residential air conditioning unit, utilizing the correct Sporlan KT-83 replacement part is critical to preventing liquid flood-back and ensuring the long-term protection of the compressor.

• Refined Superheat Control: The KT-83-FW/JW charge is stabilized for R-134a systems, preventing hunting and maintaining a consistent evaporator discharge temperature.
• Durable Construction: Features a high-grade welded element and large flat diaphragm for increased sensitivity and a longer operational life cycle.
• Direct OEM Compatibility: This 180941P part number ensures a perfect mechanical fit for Sporlan valve bodies requiring an 83-series element.
• Versatile Application: Ideal for HVACR refrigeration units, including commercial walk-ins and industrial cooling systems.

Common Questions

How do I know if my Sporlan power element is dead?
If you observe a high superheat condition that does NOT respond to adjustment, or if the valve remains closed despite a warm sensing bulb, the thermostatic charge has likely leaked out of the power element. You can test this by holding the bulb in your hand; if the suction pressure does not rise, the element is likely spent and needs replacement.

Can I use this KT-83-FW/JW element for R-404A or R-22?
No, this specific element is charged for R-134a and R-12. Using an incorrect thermostatic charge will result in poor superheat control and potential system damage. Always match the element charge to your specific refrigerant and operating temperature range.

What is the lock ring size for this element?
The KT-83 series uses a standard lock ring size consistent with Sporlan's larger-capacity replaceable elements. Always ensure the valve body threads are clean and undamaged before seating the new diaphragm to maintain a leak-proof seal.
