Description
Danfoss 067N3155 Thermal Expansion Valve — Type TGEL 10
The Danfoss 067N3155 is a high-performance, externally equalized thermal expansion valve (TXV) engineered for R410A refrigeration and air conditioning systems. Rated at 6½ tons of capacity and featuring a maximum operating pressure (MOP) of 667 PSI, this valve is purpose-built for the elevated pressures and precise superheat control demands of modern R410A equipment. The Type TGEL 10 design incorporates a straight valve body, a 60-inch capillary tube for flexible remote bulb placement, and a number 6 orifice to match the required system flow rate.

Product Overview
The external equalization port on the 067N3155 allows the valve to sense evaporator outlet pressure directly, compensating for pressure drop across the evaporator coil and delivering accurate superheat control across a wide range of operating conditions. This makes it an ideal choice for multi-circuit or longer evaporator coils where internal equalization would result in hunting or poor superheat regulation.
The 60-inch capillary tube provides ample reach for remote bulb placement on the suction line, while the included bulb strap ensures a secure, thermally conductive connection. The straight body configuration simplifies installation in tight equipment cabinets and rooftop units.
Applications
- Commercial and residential R410A air conditioning systems
- Split systems and packaged rooftop units (RTUs)
- Multi-circuit evaporator coil applications
- Systems requiring precise superheat control at elevated operating pressures
