Emerson Alco 054404 Expansion Valve

The Emerson Alco 054404, specifically the TCLE 10 HC, is a heavy-duty externally equalized thermal expansion valve designed for R22 refrigeration systems. Engineered for medium temperature applications, this 10-ton TXV features take-apart construction, allowing for straightforward field service, internal cleaning, or power assembly replacement without de-brazing the entire valve body. The inclusion of a 5-foot capillary tube provides flexible mounting options for larger evaporator coils, while the SAE external equalization ensures precise superheat control by compensating for pressure drops across the distributor and evaporator. This TXV less flange (VLF) configuration is a standard replacement component for contractors managing high-capacity light commercial cooling or process refrigeration. By utilizing a stainless steel power assembly, the 054404 resists corrosion and prevents element failure in demanding mechanical environments, ensuring consistent refrigerant flow and compressor protection through accurate 10-ton metering.

• Take-Apart Design: Simplifies maintenance by allowing access to internal components without removing the valve body from the line.
• Precise Superheat Control: The external equalizer compensates for high pressure drops, maintaining efficiency in 10-ton R22 systems.
• Square Body Construction: Provides a durable, leak-resistant foundation suitable for high-vibration HVACR environments.
• Interchangeable Components: Compatible with various TCLE series cages and power assemblies for customized system matching.
• Corrosion Resistance: Features a high-grade stainless steel diaphragm and power element for long-term reliability.

Is the 054404 compatible with R407C systems?
While R407C has similar pressure characteristics to R22, the TCLE 10 HC is specifically charged for R22 medium temperature applications. Using this valve with R407C may require significant superheat adjustment and should only be done after verifying pressure-temperature saturation curves.

What does 'TXV Less Flange' (VLF) mean for installation?
This model is supplied without the inlet/outlet flanges. If you are performing a new installation or replacing a different valve style, you must ensure you have the correct bolt-on flange kit to match your liquid and suction line diameters.

Can this valve be used for low-temperature applications?
This specific model uses an 'HC' (Medium Temp) charge. For low-temp applications (below 0°F evaporating temp), an 'LC' or 'MC' charge is recommended to prevent hunting and ensure the bulb responds correctly to suction line temperatures.
