The Nordyne 920666A 4-Ton Thermal Expansion Valve (TXV) R-22 that is meant for 4-ton size helps regulating the movement of refrigerant in air conditioning and refrigerating systems. The sensitive bulb measures the refrigerant's temperature and adjusts the valve opening so as to maintain an ideal superheat and prevent liquid refrigerant from entering into compressor. It assures efficient operation, prevention of damage on the system, and lower energy consumption. The TXV is commonly found in commercial and industrial facilities such as cold storage, supermarkets and restaurants. This device works with R-22 refrigerant.
