Sporlan Controls 181518 KT-45-ZGA Power Element R-410A with 5′ Capillary

Description

Sporlan Controls KT-45-ZGA Power Element for R-410A

The Sporlan Controls KT-45-ZGA (SKU 181518) is a precision-engineered replacement power element designed for use with R-410A refrigerant systems. As a critical component of thermostatic expansion valves (TXVs), the power element serves as the sensing and actuating assembly that monitors suction line temperature and modulates refrigerant flow to maintain optimal superheat — ensuring efficient, reliable system performance.

Sporlan, a Parker brand and industry leader in refrigeration controls, manufactures this power element to exacting tolerances for consistent field performance. The included 5-foot capillary tube provides installation flexibility, allowing the sensing bulb to be properly positioned on the suction line even in challenging equipment layouts.

Key Features

• Replacement power element for Sporlan TXV valves
• Designed and charged for use with R-410A refrigerant
• 5-foot capillary tube for flexible sensing bulb placement
• Precision-engineered for accurate superheat sensing and control
• Manufactured by Sporlan (Parker), a trusted name in refrigeration controls
• Direct OEM-style replacement for compatible Sporlan valve bodies

Application

• Residential and light commercial air conditioning systems
• Heat pump systems utilizing R-410A refrigerant
• Refrigeration systems requiring TXV power element replacement
• Compatible with Sporlan KT-45 series valve bodies

Why Replace the Power Element?

Over time, power elements can lose their refrigerant charge or develop sensing inaccuracies, leading to poor superheat control, reduced system efficiency, or compressor damage. Replacing the power element with a factory-charged Sporlan unit restores proper TXV operation without the cost of replacing the entire valve body.
