York S1-1TVM4K1 6-Ton Thermal Expansion Valve Kit 5/8" X 5/8" R410A 30"Capillary Tube

The York S1-1TVM4K1 is a high-precision thermal expansion valve (TXV) which is designed for use in HVAC systems that have a cooling capacity of 6 tons. Its special design ensures the optimized system performance and efficiency when used with R410A refrigerant. A TXV is crucial in maintaining the exact flow of refrigerant to the evaporator as a part of the system. It senses the temperature at the evaporator exit by using a capillary tube to work. The TXV changes the opening of the valve to manage the flow depending on changes in the refrigerant temperature to prevent flooding or starving of the evaporator. This fine management is the key to keeping the necessary interior conditions and providing efficient heat exchange.
