Description
Overview
The Copeland 055927 is a straight-body, externally equalized Thermal Expansion Valve (TXV) engineered for reliable refrigerant metering in medium-temperature refrigeration and air conditioning applications. Designed to work with R22 and R407C refrigerants, this valve delivers precise superheat control to protect the compressor and optimize system efficiency. The model designation HFES 1/4 HC 5FT 3/8 x 1/2 ODF S/T confirms its factory configuration for straightforward drop-in installation.
Key Features
- Refrigerant compatibility: R22 and R407C
- Capacity: 1/4 Ton
- Temperature charge: Medium temperature
- Equalization type: Externally equalized for accurate superheat control in systems with higher pressure drops across the evaporator
- Body style: Straight body for simplified inline installation
- Capillary tube length: 5 feet for flexible bulb placement
- Inlet connection: 3/8″ ODF sweat
- Outlet connection: 1/2″ ODF sweat
- Connection method: Sweat (brazed) for leak-free, permanent installation
Application
This TXV is well-suited for small commercial and residential refrigeration systems, reach-in coolers, display cases, and light air conditioning equipment operating at medium evaporator temperatures. The external equalizer port ensures stable superheat regulation even when evaporator pressure drop is a factor, making it the preferred choice over internally equalized valves in multi-circuit or longer evaporator coil configurations.
Installation Notes
- Use standard brazing procedures for 3/8″ inlet and 1/2″ outlet ODF sweat connections
- Mount the thermostatic bulb securely to the suction line at the evaporator outlet for accurate sensing
- Connect the external equalizer line to the suction line downstream of the bulb location
- Verify system refrigerant charge and superheat settings after installation
- Compatible with both R22 (legacy) and R407C (drop-in replacement) refrigerant systems
