Description
Overview
The Copeland 057439 is a medium-temperature, externally equalized thermal expansion valve (TXV) engineered for reliable refrigerant metering in commercial and light-industrial refrigeration systems. Designed for use with R502, R404A, and R507 refrigerants, this angle-body valve delivers precise superheat control at a 1.5-ton capacity rating, making it an ideal drop-in solution for reach-in coolers, display cases, and walk-in refrigeration applications.
Key Features
- Angle body configuration for flexible, space-saving installation in tight equipment layouts
- 3/8″ ODF inlet x 1/2″ ODF outlet sweat connections for clean, leak-free brazed joints
- 5-foot capillary tube for remote bulb placement and accurate sensing at the evaporator outlet
- External equalizer port compensates for evaporator pressure drop, ensuring consistent superheat across the coil
- Built-in inlet strainer protects the valve seat and orifice from debris and system contaminants
- Medium-temperature charge matched to R502, R404A, and R507 operating ranges
- 1.5-ton nominal capacity for properly sized medium-temperature refrigeration circuits
Refrigerant Compatibility
- R502 (legacy systems)
- R404A (primary low-GWP alternative)
- R507 (azeotropic blend alternative)
