Description
The York S1-025-45254-000 Thermostatic Expansion Valve (TXV) is a metering component designed to regulate flow into the evaporator based on temperature and pressure changes. It features 3/8″ x 7/8″ ODF solder connections for integration into the line set and is calibrated to operate at 93.1 PSI to maintain stable flow control under varying load conditions. The valve adjusts delivery into the coil to maintain proper superheat, preventing inefficient coil operation caused by overfeeding or underfeeding. In HVAC systems, it supports consistent cooling performance and stable heat exchange across air conditioning and heat pump equipment.
