For optimal performance, install the valve vertically near the evaporator. Ensure the temperature-sensing bulb is tightly attached to the evaporator outlet pipeline and wrapped with thermal insulation material to prevent external temperature interference. The balance tube (for external balance type) should be connected to the evaporator outlet behind the temperature-sensing bulb.
