Nordyne 920670A 3-Ton Thermal Expansion Valve (TXV) R410A

The Nordyne 920670A 3-Ton Thermal Expansion Valve (TXV) is an essential accessory in air conditioning and heat pump systems that employ R410A refrigerant. It regulates the refrigerant to the evaporator Coil to provide optimum cooling or heating as required. The evaporator pressure and temperature are detected by the TXV through a bulb and capillary tube attached. From these readings, the valve controls the refrigerant flow to achieve the set superheat and prevent the compressor from being flooded with liquid. This TXV is applicable for both residential and commercial split systems, packaged units, and heat pumps.
