Heil Quaker ICP 1178404 TXV Valve
The Heil Quaker ICP 1178404 TXV Valve is a critical refrigeration component designed for precise refrigerant metering in 4-ton cooling systems. This thermal expansion valve maintains the ideal superheat across the evaporator coil, preventing liquid slugging and ensuring compressor longevity. Engineered for ICP HVAC replacement parts compatibility, the 1178404 utilizes a sensing bulb to monitor suction line temperature, modulating flow to match fluctuating heat loads. As a genuine OEM TXV valve, it ensures seamless integration with Heil Quaker evaporator coils and high-efficiency heat pump systems. Proper installation requires professional brazing techniques and nitrogen purging to protect the internal diaphragm and needle assembly. In commercial and residential 4-ton split systems, replacing a restricted or failed expansion valve with this specific ICP part restores factory-spec pressure drops and thermal efficiency, making it the standard choice for contractors prioritizing system reliability and accurate refrigerant flow control.
Key Benefits for Technicians- Precise Superheat Regulation: Maintains optimal evaporator performance under varying ambient conditions.
- OEM Compatibility: Exact fit for Heil, Quaker, and ICP 4-ton air handlers and heat pumps.
- System Protection: Prevents refrigerant floodback to the compressor, extending the lifespan of the entire HVAC circuit.
- Durable Construction: Built to withstand high-pressure environments common in modern R-410A systems.
What are the symptoms of a failing 1178404 TXV?
Common indicators include frost on the evaporator coil, high suction superheat, or low suction pressure while the liquid line pressure remains normal.
Is this valve compatible with R-22 or R-410A?
This 4-ton valve is specifically designed for high-pressure R-410A applications found in modern ICP equipment.
Does this valve include the sensing bulb and mounting hardware?
Yes, this assembly includes the integrated sensing bulb required for accurate thermal feedback from the suction line.
