One of the objectives of The News has been to help those servicing equipment to better understand the parts and equipment in order to diagnose and troubleshoot problems more effectively. In the September 11, 1950 issue, the function of thermostatic expansion valves (TXVs) was the topic under consideration in an article by Paul Reed.
"It is perhaps unfortunate that the thermostatic expansion valve is called a 'thermostatic' expansion valve," he wrote. "It gives the impression that the valve is to be used to control temperatures in somewhat the same way that a thermostat does. This is not true."
