Description
The Copeland 057378 is a precision-engineered Thermal Expansion Valve (TXV) designed for reliable refrigerant metering in heat pump systems. Built to handle R22 and R407C refrigerants at a 5.5-ton capacity, this valve delivers consistent superheat control and efficient system performance across a wide range of operating conditions.
Key Features
- Refrigerant compatibility: R22 and R407C
- Nominal capacity: 5.5 tons (heat pump charge)
- Body style: Angle body configuration for flexible installation
- Connection type: Sweat (ODF) — 1/2″ inlet x 5/8″ outlet
- Capillary tube length: 5 feet for remote bulb placement flexibility
- Equalization type: Externally equalized for accurate superheat sensing in systems with higher pressure drops
- Model number: HFES 5 1/2 HCA 5FT 1/2 x 5/8 ODF ANG
Product Details
- SKU: 057378
- Brand: Copeland
- Valve type: Thermal Expansion Valve (TXV)
- Application: Heat pump systems
- Inlet connection: 1/2″ ODF sweat
- Outlet connection: 5/8″ ODF sweat
- Capillary tube: 5 ft.
- Equalization: External
Why Choose External Equalization?
Externally equalized TXVs are the preferred choice for systems with distributor nozzles or longer evaporator circuits where refrigerant pressure drop is a factor. By sensing pressure at the evaporator outlet rather than the inlet, the external equalizer line ensures accurate superheat control, protecting the compressor and maximizing system efficiency.
Applications
- Residential and light commercial heat pump systems
- R22 retrofit and R407C replacement applications
- Systems requiring precise superheat management
- Split-system air conditioning and heat pump installations
