Description
The York S1-02538739060 Expansion Valve is a TXV for R410A with 3/8 inch ODM by 3/8 inch ODF connections, a 30-inch capillary, and a 98.0 PSIG setting, used to regulate refrigerant flow into the evaporator in HVAC systems. It meters based on sensed temperature and pressure to maintain proper superheat. It operates through a sensing bulb and internal diaphragm that adjust valve position according to load demand. Installed at the evaporator inlet within refrigerant lines, it works with system components to control refrigerant distribution and maintain stable cooling operation.
