The Sporlan 180921, also identified as the KT-83-VZ Element Kit, is a critical replacement component for field-serviceable Thermostatic Expansion Valves (TXVs). Featuring a Size 83 element and a Z charge specifically engineered for R-22 systems, this kit is designed for low-temperature applications where precise superheat control is required. The 5-foot capillary tube provides sufficient length for remote bulb placement on the suction line, ensuring accurate feedback to the power head. For technicians servicing industrial refrigeration or commercial HVAC systems, the Sporlan KT-83-VZ allows for direct power element replacement without removing the entire valve body from the line, significantly reducing downtime. The stainless steel diaphragm and rugged construction ensure the R-22 expansion valve element maintains calibration under varying pressure conditions. When troubleshooting hunting or a loss of charge in a Sporlan thermostatic valve, this genuine 180921 replacement kit provides the technical precision necessary to restore system efficiency and prevent compressor slugging. Key Benefits Precise Superheat Regulation: The Z-charge is optimized for low-temperature suction pressures, ensuring the R-22 refrigerant flow remains stable. Field Service Efficiency: Direct compatibility with Sporlan Size 83 valve bodies facilitates a faster TXV power element replacement. Durable Capillary Design: A 60-inch (5-foot) capillary tube offers flexibility for proper bulb mounting and insulation. OEM Reliability: Genuine Parker Sporlan parts ensure the internal diaphragm meets exact factory specifications for long-term reliability. Common Questions Is the KT-83-VZ compatible with refrigerants other than R-22? The V-code indicates a specific R-22 charge; using this with other refrigerants may lead to improper superheat and potential system failure. What does the 'Z' charge signify in this Sporlan kit? The Z-charge is a specialized thermostatic charge designed primarily for low-temperature refrigeration applications to maintain consistent control at lower evaporator temperatures. Does this kit include the replacement gasket? Standard Sporlan element kits typically include the necessary replacement gaskets to ensure a leak-proof seal during the reassembly of the power head to the valve body.
