Heil Quaker ICP 1174451 TXV

Professional-grade Heil Quaker ICP 1174451 TXV, also identified by part number 1174451, is a high-precision thermostatic expansion valve engineered for 2-3 ton residential and light commercial cooling systems. Specifically designed for R-22 refrigerant, this direct OEM replacement ensures accurate superheat control across varying load conditions. It functions as a critical metering device, reducing high-side pressure to facilitate optimal heat absorption within the evaporator coil. Trusted by veteran technicians, this thermal expansion valve is a compatible fit for various International Comfort Products (ICP) brands, including Heil, Tempstar, Arcoaire, and Comfortmaker. Designed to maintain system equilibrium and protect the compressor from liquid slugging, this TXV supports equipment longevity and consistent cooling output in legacy systems. Use this valve to restore factory-spec refrigerant flow and maximize COP (Coefficient of Performance) in 24k to 36k BTU units.

• Precise Refrigerant Metering: Delivers exact R-22 flow to the evaporator, preventing frost-ups and ensuring balanced superheat levels.
• System Compatibility: Fully compatible with ICP evaporator models like EBA2X24BA2, EBA2X30BA2, and EBA2X36BA2.
• Compressor Protection: Limits the risk of liquid refrigerant return, significantly reducing mechanical wear and tear on the HVAC compressor.
• Optimized Efficiency: Enhances the heat transfer process, allowing 2 to 3-ton systems to operate at peak thermal capacity.

Is the ICP 1174451 compatible with R-410A systems?
No, this specific TXV is strictly calibrated for R-22 refrigerant. Using it with R-410A will cause incorrect pressure drops and potential system failure.

What symptom indicates a failing 1174451 expansion valve?
Common indicators include high superheat, frost buildup on the evaporator inlet, or a starving coil leading to low suction pressure despite a full refrigerant charge.

Can this valve be used on both 2-ton and 3-ton units?
Yes, the 1174451 is a versatile 2-3 ton TXV designed to modulate flow for cooling capacities ranging from 24,000 to 36,000 BTUs.
