Description
The Danfoss 067N9403 is a heavy-duty, externally equalized Thermal Expansion Valve (TXV) engineered for reliable refrigerant flow control in commercial and light-industrial refrigeration and air conditioning systems. Designed for use with R22 and R407C refrigerants, this Type TGEX 10 valve delivers precise superheat control at capacities up to 6 tons, making it an ideal drop-in solution for demanding cooling applications.
Featuring a straight-body configuration with 1/2″ ODF inlet and 5/8″ ODF outlet connections, the 067N9403 integrates seamlessly into standard copper line sets. The 60″ capillary tube provides flexible bulb placement during installation, while the included bulb strap ensures secure, consistent thermal sensing contact. The number 6 orifice is factory-installed and sized to match the rated system capacity.
External equalization allows the valve to compensate for pressure drop across the evaporator, maintaining accurate superheat control even in longer or more complex coil circuits. The high Maximum Operating Pressure (MOP) rating of 667 PSI provides a reliable safeguard against compressor floodback during startup and high-load conditions.
