Description
Danfoss 067N3156 Thermal Expansion Valve (Type TGEL 10) — Overview
The Danfoss 067N3156 is a high-performance, externally equalized thermal expansion valve (TXV) engineered for reliable refrigerant metering in commercial and light-commercial R410A systems. Rated at 9 tons of cooling capacity and featuring a maximum operating pressure (MOP) of 667 PSI, this valve is purpose-built for the elevated pressures inherent to R410A refrigerant applications. The straight-body design with a 5/8″ ODF inlet and 7/8″ ODF outlet ensures straightforward integration into standard refrigeration piping configurations.

Application & Benefits
The external equalization port compensates for pressure drops across the evaporator, making the Danfoss 067N3156 ideal for multi-circuit evaporators and longer evaporator coils where internal equalization would result in poor superheat control. The 60″ capillary tube provides installation flexibility, allowing the thermal sensing bulb to be positioned at the optimal location on the suction line for accurate superheat sensing. The included bulb strap ensures a secure, thermally conductive connection between the sensing bulb and the suction line.
Danfoss TXVs are trusted by HVAC/R professionals worldwide for their precision engineering, consistent performance, and long service life — making the 067N3156 a dependable choice for new installations and replacement applications in commercial R410A refrigeration and air conditioning systems.
