Description
Overview
The Copeland 058421 is a precision-engineered Thermal Expansion Valve (TXV) designed for medium-temperature refrigeration and air conditioning applications. Carrying the model designation HFESC 2 1/2 MC 5FT 3/8×1/2 ODF ANG, this externally equalized valve delivers accurate refrigerant metering for 2-1/2 ton capacity systems, ensuring optimal evaporator performance and system efficiency.
Refrigerant Compatibility
- R-12
- R-134a
- R-450A
- R-513A
Key Features
- 2-1/2 Ton medium temperature capacity charge
- Externally equalized design for accurate superheat control across longer evaporator circuits
- 3/8″ inlet x 1/2″ outlet sweat (ODF) connections for straightforward brazing installation
- 5-foot capillary tube for flexible bulb placement and remote sensing
- Angled (ANG) valve body orientation for versatile system layout integration
- Compatible with modern HFO/HFC refrigerant blends including R-450A and R-513A, making it suitable for retrofit and new installations
Application
This TXV is ideal for commercial refrigeration cases, walk-in coolers, and medium-temperature air conditioning systems where precise superheat control is critical. The external equalizer port connects to the evaporator outlet, compensating for pressure drop across the evaporator coil and maintaining consistent superheat regardless of load variations. Its compatibility with both legacy refrigerants (R-12, R-134a) and newer low-GWP alternatives (R-450A, R-513A) makes it a versatile choice for new builds and system upgrades.
