Description
The York S1-022-12990-000 4-Ton Thermal Expansion Valve is the component that regulates the amount of refrigerant in R-410A HVAC systems. It regulates the degree of refrigerant passing through the evaporator coil to serve the cooling needs of the system. This draws a variety of applications in modifying refrigerant flow, preventing the icy formation in the system, and enhancing efficiency. This 4-ton TXV is designed for mid-range home or commercial air conditioning and heat pump applications. The valve is critical in maintaining improved cooling efficiency, longer equipment life, and higher energy economy.
