The Trane VAL08796 is a genuine OEM thermal expansion valve (TXV) designed for 3‑ton R‑410A systems. This valve regulates refrigerant flow for proper superheat and system efficiency. This is the exact OEM part used in many Trane and American Standard heat pumps and air conditioners — not an aftermarket substitute.
