Singer Valve 207C Thermostatic Expansion Valve

The Model 207C Thermostatic Expansion Valve is a vintage TXV that provides precise, adjustable superheat control for refrigerant flow into evaporators in small commercial refrigeration equipment. In some listings it’s labeled Singer 207C, but historical references attribute the model to Automatic Products Company of Milwaukee, dating from around 1950. The 207C was designed for use with mid‑century refrigerants such as methyl chloride and Freon 12 (R‑12) and was marketed as part of a compact line for small commercial appliances. As an adjustable superheat valve, the device lets technicians set the desired superheat level at the evaporator outlet, enabling more stable evaporator temperatures and efficient heat transfer across varying load conditions. This model illustrates mid‑century TXV design, balancing compact form with the reliability expected from early expansion valves. Suitable for restoration or legacy installations that match the era’s fittings and refrigerants, the 207C remains a reference point for vintage refrigeration control technology.
