Carrier KSATX0301PUR TXV Valve Kit

The Carrier KSATX0301PUR TXV Valve Kit is a field-installed metering device designed for 3 to 3.5-ton HVAC systems utilizing R-410A refrigerant. This Puron balanced port hard shut-off TXV is engineered for precise refrigerant flow control, ensuring the evaporator coil receives the exact superheat required for optimal heat transfer. Built with a heavy-duty copper body, it features sweat or braze connections to maintain a leak-free seal under high-pressure conditions. By replacing inferior fixed orifices, this thermal expansion valve kit significantly improves cooling system efficiency and helps protect the compressor from liquid slugging during low-load periods. For contractors, this OEM kit is the standard for Puron energy efficiency upgrades and residential AC repair, providing a direct fit for compatible 24ABB and 24ABC series condensing units. Its robust design ensures consistent performance and reliability in demanding light commercial and residential split systems without the need for frequent recalibration.

• Precise Refrigerant Metering: Maintains optimal superheat across varying load conditions to maximize evaporator efficiency.
• System Reliability: The hard shut-off design prevents refrigerant migration to the compressor during the off-cycle.
• Durability: High-grade copper construction with sweat/braze connections for secure, long-term installation.
• Broad Compatibility: Tailored for 3-3.5 ton units, supporting a wide range of Carrier and Bryant R-410A models.
• Enhanced Cooling Capacity: Stabilizes performance to ensure consistent discharge temperatures and reduced energy consumption.

Is this TXV compatible with older R-22 systems?
No, the Carrier KSATX0301PUR is specifically calibrated for R-410A (Puron) systems and should not be used with R-22 refrigerants due to different pressure requirements.

Does this kit require a specific installation orientation?
The valve should be installed following standard refrigerant piping practices, typically as close to the evaporator inlet as possible, with the sensing bulb secured to the suction line in the 10 o'clock or 2 o'clock position.

Can this be used on a 2-ton or 5-ton unit?
This specific kit is sized for 3 to 3.5-ton capacities. Using a valve with an incorrect tonnage rating will cause improper metering, leading to coil freezing or compressor damage.
