Sporlan 180318 KT-43-SZ Power Element

The Sporlan 180318 KT-43-SZ Power Element is a critical replacement component for thermostatic expansion valves (TEVs) operating in low-temperature refrigeration environments. Featuring a 5-foot capillary tube (60 inches), this Type 43 power element is engineered for precision and reliability. It utilizes a Z-charge, specifically optimized for systems utilizing R-404A, R-502, or R-507 refrigerants within an operational range of -40°F to 0°F. For contractors servicing commercial walk-in freezers or industrial cold storage, this OEM part ensures accurate superheat control and refrigeration system efficiency. The stainless steel diaphragm and durable construction provide the necessary mechanical strength to withstand high-pressure fluctuations, reducing the risk of sporlan valve failure and system downtime. This element is compatible with a wide range of Sporlan valve bodies, including the N, RCVE, F, and BF series, making it a versatile HVACR replacement part for your field service kit.

• Optimized for Low-Temp: The Z-charge thermostatic element is specifically designed for applications ranging from -40°F to 0°F, ensuring stable evaporator performance.
• Universal Compatibility: Fits various Sporlan valve series such as F, BF, SBF, Q, and SQ, allowing for streamlined refrigeration valve maintenance.
• Extended Reach: The 5' capillary length provides flexibility for bulb placement in complex piping configurations.
• OEM Precision: Genuine Parker Sporlan 180318 construction guarantees millisecond response times to load changes, preventing liquid slugging of the compressor.

What refrigerant types is the KT-43-SZ compatible with?
This power element is primary used with R-404A, but is also suitable for R-502, R-408A, and R-507 systems in low-temperature applications.

Will this element fit my existing valve body?
The Type 43 element is standard for many Sporlan small-to-medium capacity valves. Check the nut size and series (e.g., F, BF, or Q) to confirm a match with the 180318 model.

How do I know if my power element has lost its charge?
Symptoms typically include a valve that stays closed or high superheat readings that cannot be adjusted. Replacing the power element is the standard procedure for restoring proper HVAC expansion valve modulation.
