Sporlan 183387 KT-43-SC Element Kit

The Sporlan 183387 KT-43-SC Element Kit is a professional-grade thermostatic expansion valve power head replacement designed for commercial refrigeration and HVAC service. Featuring a 30-inch capillary tube, this Type 43 element is specifically engineered for systems utilizing R-404A, R-502, and R-408A refrigerants. As a direct replacement for the discontinued 180330, the 183387 incorporates a Type C thermostatic charge, making it the industry standard for medium and low-temperature applications where precise superheat control is critical for system stability. The large, flat stainless steel diaphragm provides the sensitivity required to manage widely varying load conditions, preventing liquid slugging while maximizing evaporator efficiency. For technicians performing field repairs on Sporlan TXVs, this genuine OEM kit ensures seamless compatibility with standard valve bodies, maintaining the hydraulic integrity of the refrigeration circuit without requiring extensive piping modifications.

• Universal Compatibility: Serves as the official replacement for 180330 and 181530, ensuring a perfect fit on existing Sporlan valve bodies.
• Precise Superheat Control: The Type C charge is optimized for commercial refrigeration, providing reliable performance in walk-in coolers and freezers.
• Durable Construction: Features a stainless steel diaphragm and laser-welded element for high-pressure reliability and resistance to corrosion.
• Extended Reach: The 30-inch capillary length offers flexibility for remote bulb placement on various evaporator orientations.

Is the Sporlan 183387 compatible with R-404A systems?
Yes, this KT-43-SC element kit is specifically designed for the R-404A/R-507 refrigerant family, commonly used in medium and low-temp refrigeration applications.

Will this replace my older 180330 power head?
Correct. The 183387 is the direct engineering successor to the 180330, maintaining the same technical specs and mounting footprint.

What does the "C" charge indicate in the specifications?
The C charge refers to the thermostatic charge type, which is calibrated for refrigeration applications to provide a rapid response to suction line temperature changes.
