Description
The Danfoss 067N9556 is a TGE-series Thermostatic Expansion Valve (TXV) designed specifically for use with R454B, a low-GWP A2L refrigerant widely adopted as a next-generation replacement in commercial and residential refrigeration and air conditioning systems. Engineered to Danfoss’s exacting standards, this TXV delivers accurate superheat control to optimize system efficiency, protect the compressor, and maintain stable operation across varying load conditions.
Product Overview
Danfoss TGE-series expansion valves are precision-engineered flow-control devices that meter refrigerant into the evaporator based on real-time superheat feedback. The 067N9556 is factory-calibrated for R454B, ensuring compatibility with modern low-GWP system designs and retrofit applications transitioning away from higher-GWP refrigerants such as R410A.
