Product Overview
The DANFOSS TE2 (Model 068Z3422) is a high-precision thermostatic expansion valve (TXV) engineered for regulated refrigerant injection in industrial and commercial refrigeration and air-conditioning systems. Manufactured by Danfoss, a global leader in thermal management and fluid control technology, the TE2 series operates on a balanced-port thermostatic principle, modulating refrigerant mass flow in direct response to evaporator superheat. This ensures optimal evaporator utilization, stable system superheat control, and protection of the compressor against liquid slugging. The valve is a critical metering component within the refrigeration circuit, functioning as a precision throttling device rather than a pump, and is compatible with a broad range of HCFC, HFC, and HFO refrigerants depending on orifice and charge configuration.
