Description
Copeland 063649 Thermal Expansion Valve Overview
The Copeland 063649 is a high-performance Thermal Expansion Valve (TXV) engineered for reliable refrigerant metering in residential and light commercial HVAC systems. Designed for use with R22 and R407C refrigerants, this valve delivers precise superheat control and consistent system performance across a wide range of operating conditions.
Key Features
- Compatible refrigerants: R22 and R407C
- Rated capacity: 5 Ton
- Wide range charge for broad operating flexibility
- Externally equalized design for accurate pressure sensing and superheat control
- Straight body configuration for straightforward installation
- 30″ capillary tube for flexible bulb placement
- Inlet connection: 3/8″ ODF sweat
- Outlet connection: 1/2″ ODF sweat
- Model: AAE 5 HAA 30IN 3/8 X 1/2 ODF S/T
Design & Construction
The straight body design simplifies installation in tight equipment spaces, while the sweat (ODF) connections ensure secure, leak-free brazed joints. The 30″ capillary tube provides ample length to position the sensing bulb at the optimal location on the suction line, supporting accurate superheat measurement and stable system operation.
Wide Range Charge & External Equalization
The wide range charge allows this TXV to maintain consistent performance across varying load conditions, making it well-suited for systems that experience fluctuating evaporator pressures. The external equalizer port compensates for pressure drop across the evaporator coil, ensuring the valve responds accurately to true suction line conditions rather than evaporator inlet pressure alone — a critical feature for multi-circuit or longer evaporator coil applications.
Applications
- Split-system air conditioners and heat pumps
- R22 and R407C refrigerant systems up to 5 tons
- Residential and light commercial HVAC equipment
- Replacement or retrofit TXV installations
