Copeland Comfort Control (Alco) 054927 Expansion Valve

The Copeland Comfort Control (Alco) 054927 Expansion Valve is a 1 Ton TXV engineered for medium temperature applications using R22 or R407C refrigerant. As an HF 1 HC 5FT 3/8 X 1/2 SAE S/T model, it features a straight-body design with 3/8" x 1/2" flare connections, allowing for efficient integration into existing liquid lines without brazing. The 5-foot capillary tube provides necessary reach for external sensing bulb placement, ensuring precise superheat control and protecting the compressor from liquid slugging. This thermal expansion valve utilizes a HC-type charge specifically calibrated for medium temperature refrigeration and HVAC systems, maintaining high evaporator efficiency across fluctuating load conditions. For technicians replacing an Alco 054927, this OEM component ensures original factory specifications are met for refrigerant flow regulation and system balance.

• Dual Refrigerant Compatibility: Hard-coded for R22 and R407C, making it a versatile choice for retrofits and legacy system maintenance.
• Mechanical Flare Connections: The 3/8" inlet and 1/2" outlet SAE flare fittings eliminate the need for torches in tight spaces, reducing installation time.
• Stable Superheat Regulation: Engineered to provide consistent pressure drop across the orifice, ensuring the evaporator remains active without starving or flooding.
• Industrial Durability: The Alco HF series is known for a stainless steel power element and a compact, rugged body that resists corrosion in demanding environments.

Can this TXV be used with R410A systems?
No, the Copeland 054927 is specifically charged for R22 and R407C. Using it with R410A will lead to improper superheat and potential compressor failure due to the significant pressure differences.

Is this a balanced port expansion valve?
This model is a standard HF series valve. While it offers excellent modulation for 1 Ton systems, it is optimized for systems with relatively constant head pressures typical of medium-temp applications.

What is the benefit of the straight-body configuration?
The straight-through flow design simplifies piping layouts where an angle-body valve would require additional elbows or re-piping of the liquid line.
