Description
Overview
The Copeland 057446 is a precision-engineered Thermal Expansion Valve (TXV) designed for reliable refrigerant metering in commercial refrigeration and HVAC applications. With a 1-ton capacity rating and a 45 PSI Maximum Operating Pressure (MOP) charge, this valve delivers consistent superheat control and system protection across a wide range of operating conditions.
Refrigerant Compatibility
This TXV is rated for use with multiple refrigerants, making it a versatile replacement or new-installation choice:
- R507
- R502
- R404A
- R448A
- R449A
Key Features
- 1-Ton capacity rating for light commercial and refrigeration systems
- 45 PSI MOP (Maximum Operating Pressure) charge prevents evaporator flooding at startup and high-load conditions
- Externally equalized design compensates for pressure drop across the evaporator, ensuring accurate superheat control
- 3/8″ inlet x 1/2″ outlet ODF sweat connections for straightforward copper tube installation
- 5-foot capillary tube with remote sensing bulb for precise temperature sensing at the evaporator outlet
- Angular (ANG) body configuration for flexible installation orientations
- Part number / model: HFESC 1 RW45 5FT 3/8×1/2 ODF ANG
Application
Ideal for walk-in coolers, reach-in cases, refrigerated display cases, and other commercial refrigeration systems requiring precise evaporator superheat management. The external equalizer port connection ensures accurate valve response even in systems with multi-circuit or distributor-fed evaporators where significant pressure drop is present.
