Carrier KSATX0701HSO R22 TXV

The Carrier KSATX0701HSO R22 TXV is a critical metering device designed for high-tonnage 4-ton cooling applications. This thermostatic expansion valve kit features a balanced port, hard shutoff design that eliminates bleed-through during the off-cycle, ensuring maximum system efficiency and preventing refrigerant migration. As a bi-flow valve, it is compatible with both split-system air conditioners and heat pumps, providing precise superheat control across varying load conditions. For technicians performing an R-22 piston to TXV conversion on older Carrier, Bryant, or Payne units, this kit is the standard solution to optimize evaporator coil performance. The assembly includes a 7/8-inch vapor adapter, external equalizer tube, and a drop-in strainer to protect the valve orifice from debris. When installing, always wrap the valve body in a heat-sinking material and ensure the sensing bulb is properly insulated and secured to the suction line to maintain accurate refrigerant flow regulation.

• Hard Shutoff Design: Prevents refrigerant bleed-through after system shutdown, protecting the compressor and maintaining pressure differentials.
• Balanced Port Construction: Compensates for changes in head pressure, ensuring consistent superheat levels in both high and low ambient temperatures.
• Complete Installation Kit: Includes the TXV valve, specialized vapor elbow with equalizer adapter, copper bulb straps, and necessary gaskets for a professional field installation.
• Bi-Flow Capability: Engineered for versatility in R-22 heat pump applications, allowing for seamless operation in both heating and cooling modes.
• Enhanced System Efficiency: Improves the SEER rating of existing 4-ton HVAC systems by providing more precise refrigerant metering than standard fixed-orifice pistons.

Is the KSATX0701HSO compatible with R-410A systems?
No, this specific kit is engineered exclusively for R-22 refrigerant. Using this valve with R-410A will lead to improper metering and potential system failure due to the different pressure requirements.

Do I need to remove the existing indoor piston before installing this TXV?
Yes. For the TXV kit to function correctly, any factory-installed indoor piston or orifice must be removed from the furnace coil or fan coil before the expansion valve is brazed into the liquid line.

Can this valve be mounted in any orientation?
While the Carrier KSATX0701HSO can be mounted in various positions, an upright orientation is preferred. Avoid mounting the valve upside down, as this can allow debris to settle on the internal check valve seat.
