Description
Overview
The Copeland 057781 is a heavy-duty externally equalized thermal expansion valve (TXV) engineered for reliable refrigerant metering in medium-temperature commercial refrigeration and air conditioning systems. Designed for use with R22 and R407C refrigerants, this valve delivers precise superheat control at a 5.5-ton capacity, making it a trusted choice for demanding HVAC/R installations.
Key Features
- Capacity: 5.5 Ton — suited for medium-to-large commercial applications
- Compatible Refrigerants: R22 and R407C
- Charge Type: Medium Temperature — optimized for medium-temperature system operating ranges
- Equalization: Externally equalized for accurate superheat control in systems with significant pressure drop across the evaporator
- Body Style: Angle body configuration for flexible installation in tight or angled piping layouts
- Connection Type: Sweat (ODF) — 3/8″ inlet x 1/2″ outlet
- Capillary Tube: 5-foot capillary tube for remote bulb placement flexibility
- Inlet Strainer: Built-in inlet strainer helps protect the valve seat and internals from debris and particulate contamination
- Model Number: HFESC 5 1/2 HC 5FT 3/8 x 1/2 ODF ANG
Application
This TXV is ideal for use in commercial refrigeration systems, split-system air conditioners, and other medium-temperature HVAC/R equipment utilizing R22 or R407C refrigerant. The externally equalized design ensures consistent superheat control even when evaporator pressure drop is a factor, improving system efficiency and protecting the compressor from liquid slugging.
