Heil Quaker ICP 1174452 TXV

Ensure precise refrigerant metering and system stability with the Heil Quaker ICP 1174452 TXV. This genuine OEM thermostatic expansion valve is engineered for high-performance residential and light commercial air conditioning systems using R22 refrigerant. Designed with a capacity range of 3.5 to 4.0 tons, this bi-flow TXV provides the versitility required for both cooling-only units and heat pump applications where bi-directional flow is essential for maintaining superheat.

The ICP 1174452 thermal expansion valve features a robust mechanical braze connection and a precision-calibrated power element to prevent liquid slugging and compressor floodback. By reacting dynamically to evaporator load changes, this valve optimizes heat transfer across the coil, ensuring your 3.5-4 ton R22 system operates at peak efficiency. This kit serves as a direct drop-in replacement for worn or fouled metering devices, maintaining original equipment specifications without the need for field modifications.

• OEM Compatibility: Exact replacement for ICP, Heil, Arcoaire, and Comfortmaker 3.5 to 4.0-ton systems.
• Bi-Flow Design: Ideal for heat pump applications, allowing for controlled metering in both heating and cooling cycles.
• System Protection: Actively manages superheat to protect the compressor from liquid refrigerant entry.
• Optimized Efficiency: Precision orifice design ensures stable evaporator pressures and consistent subcooling.

• What are the signs of a failing 1174452 TXV? Technicians should look for high superheat, low suction pressure, or frost buildup at the valve outlet, often indicating a restricted orifice or lost bulb charge.
• Can this be used with R410A systems? No, this valve is specifically calibrated for the pressure-temperature characteristics of R22 refrigerant and should not be used in R410A applications.
• Where should the sensing bulb be mounted? For optimal tracking, mount the bulb on a horizontal suction line at the 4 or 8 o?clock position, ensuring it is properly insulated and secured with the provided straps.
