Description
Copeland 065868 Thermal Expansion Valve with Internal Check Valve
The Copeland 065868 (Model AACE 3 HCA 5FT 3/8 x 1/2 ODF S/T) is a precision-engineered thermal expansion valve (TXV) designed specifically for heat pump applications. Featuring an integrated internal check valve, this valve streamlines system design by combining two critical refrigeration functions into a single, compact component — eliminating the need for a separate check valve in the liquid line.
Built for reliable performance with R22 and R407C refrigerants, this externally equalized TXV delivers accurate superheat control at a 3-ton capacity rating, making it an ideal replacement or OEM-spec component for residential and light commercial heat pump systems.

Application
The Copeland 065868 TXV is engineered for heat pump systems where precise refrigerant metering and bidirectional flow capability are essential. The external equalizer port compensates for pressure drops across the evaporator distributor, ensuring consistent superheat control under varying operating conditions. The built-in internal check valve allows the valve to function correctly during both heating and cooling cycles, making it a purpose-built solution for heat pump installations using R22 or R407C refrigerant.
