Description
The Copeland 065875 (Model AACE 5 ZW195 5FT 3/8 X 1/2 ODF S/T) is a precision-engineered Thermal Expansion Valve (TXV) designed for reliable refrigerant metering in R410A systems up to 5 tons of cooling capacity. Featuring external equalization for accurate superheat control and a built-in internal check valve for bi-directional system compatibility, this valve is an ideal choice for demanding residential and light commercial HVAC applications.
Key Features
- Refrigerant: R410A compatible
- Capacity: 5 Ton
- Body Style: Straight body for straightforward inline installation
- Connection Type: Sweat (ODF) — 3/8″ inlet x 1/2″ outlet
- Capillary Tube Length: 5 feet for flexible remote bulb placement
- Low Temperature MOP (Maximum Operating Pressure) Charge: 195 PSI — protects the compressor from low-temperature overload conditions
- Externally Equalized: Compensates for pressure drop across the evaporator for precise superheat control

Application
This TXV is well-suited for split-system air conditioners and heat pumps using R410A refrigerant. The externally equalized design makes it particularly effective on evaporators with significant refrigerant-side pressure drop, ensuring consistent superheat across varying load conditions. The 195 PSI MOP charge provides compressor protection during low-load or low-ambient operating conditions, while the integrated check valve simplifies heat pump installations by supporting reverse-cycle operation without additional components.
