Emerson Flow Control (Alco) 056225 Thermostatic Expansion Valve 3/8x1/2 ODF Straight

The Emerson Flow Control (Alco) 056225 is a thermostatic expansion valve (TXV) from the HFES series, designed for precision refrigerant flow control in HVAC and refrigeration systems. This valve features a straight body configuration with 3/8 inch x 1/2 inch ODF (sweat) connections, making it suitable for residential and light commercial applications.

Key Features:

• HFES series balanced port construction for stable superheat control
• 3/8 inch inlet x 1/2 inch outlet ODF connections for direct brazing
• Straight body design for streamlined installation
• Compatible with multiple refrigerants including R22, R407, and others
• Replaceable thermostatic element for serviceability
• Built-in mesh strainer to protect valve internals from contaminants

This thermostatic expansion valve automatically regulates refrigerant flow into the evaporator based on superheat measurement, ensuring optimal cooling efficiency while preventing liquid floodback to the compressor. The balanced port design provides reliable performance across varying operating conditions and pressure drops.
