Description
The Copeland 066148 (Model TFES 12 ZAA 7/8 X 1 1/8 ODF S/T) is a high-performance Thermal Expansion Valve (TXV) engineered for reliable refrigerant metering in R410A systems. Featuring a straight body design with sweat (ODF) connections, this valve delivers precise superheat control across a wide range of operating conditions, making it a versatile choice for residential and light commercial cooling applications.
Key Features
- Refrigerant: R410A compatible
- Capacity: 1–2 Ton
- Inlet Connection: 7/8″ ODF Sweat
- Outlet Connection: 1-1/8″ ODF Sweat
- Body Style: Straight Body
- Capillary Tube Length: 10 Feet
- Charge Type: Wide Range Charge for broad operating flexibility
- Equalization: Externally Equalized for accurate superheat control in systems with higher pressure drops
Product Details
The wide range charge allows this TXV to maintain consistent performance across varying load conditions, reducing the need for multiple valve SKUs in the field. External equalization ensures the valve responds to actual evaporator outlet pressure rather than inlet pressure, providing superior superheat stability — especially in multi-circuit or longer evaporator coil applications.
Applications
- R410A residential and light commercial split systems
- Direct expansion (DX) evaporator coil assemblies
- Systems requiring externally equalized refrigerant flow control
- Replacement or retrofit TXV installations
