The 067N3189 is a thermostatic expansion valve designed for refrigeration and air conditioning systems. It functions as a throttling device that regulates the flow of refrigerant liquid into the evaporator based on the outlet temperature and pressure, known as superheat. The valve features a solder inlet connection type with an ODF (O-ring flare) and a 1 1/8-inch inlet size. It is suitable for use with refrigerants such as R410A and has a maximum working pressure of 49 bar (711 psig). The capillary tube length is 118 inches (3000 mm), and the connection material is copper. This component is essential for controlling refrigerant flow to ensure system efficiency and proper operation.
