Parker ge1/2fw Thermostatic Expansion Valve 0.5 Ton External Equalizer 1/4 X 1/2 Inches Flare

Product Description

The Parker GE1/2FW is a thermostatic expansion valve, commonly called a TXV or TEV, designed for use in refrigeration and air conditioning systems rated at 0.5 ton capacity. This valve includes an external equalizer connection, which allows it to work accurately in systems where there is a measurable pressure drop across the evaporator coil. The external equalizer senses pressure at the evaporator outlet rather than the inlet, giving the valve more precise control over refrigerant flow. This results in better superheat regulation and improved system efficiency. The inlet connection measures 1/4 inches and the outlet connection measures 1/2 inches, both in a flare configuration. Flare fittings are a standard choice in HVAC and refrigeration work because they create a secure, leak-resistant seal without requiring brazing. HVAC technicians and refrigeration mechanics rely on thermostatic expansion valves to meter the correct amount of refrigerant into the evaporator coil. Too much refrigerant causes flooding and liquid slugging, which can damage the compressor. Too little refrigerant causes the evaporator to run warm and reduces cooling capacity. A properly sized TXV like the GE1/2FW keeps superheat within the correct range, protecting the compressor and maximizing system performance. Parker is a well-established manufacturer of fluid control and motion control components, and their expansion valves are used across residential, light commercial, and commercial refrigeration applications. The GE1/2FW is suitable for service and replacement work on small split systems, mini splits, and compact refrigeration units. HVAC technicians performing TXV replacements or system retrofits will find this valve a reliable, drop-in solution for half-ton applications requiring an external equalizer and flare connections.

• External equalizer port for accurate superheat control across evaporators with high pressure drop
• Flare inlet at 1/4 inches and flare outlet at 1/2 inches for secure, leak-resistant connections without brazing
• Rated for 0.5 ton capacity, suitable for small split systems and compact refrigeration equipment

Product Highlights

The Parker GE1/2FW thermostatic expansion valve delivers precise refrigerant metering for half-ton systems using an external equalizer and standard flare connections, making it a dependable replacement or service part for HVAC and refrigeration technicians.
