Description
The York S1-022-13989-000 Thermal Expansion Valve (TXV) 3/8″ x 5/8″ 89.3 PSI is a refrigerant metering apparatus used to regulate the flow of coolant into the evaporator based on system demand. It operates through a sensing bulb and diaphragm mechanism that adjusts the valve opening to maintain proper superheat and efficient heat exchange. It is mounted at the vaporizer inlet with secure connections and proper lamp placement for accurate detection. Positioned within HVAC systems such as air conditioners and reticulation units, it supports controlled refrigerant flow, improves cooling efficiency, and ensures stable system performance.
