The Thermal Expansion Valve (TXV) is designed specifically for systems with a 5-ton capacity and utilizes R-22 refrigerant. It serves as a crucial component in regulating refrigerant flow within the system, ensuring optimal performance and efficiency. By precisely controlling the flow of refrigerant, the TXV helps maintain consistent cooling capacity and prevents issues such as refrigerant floodback or insufficient cooling. Its compact design and compatibility with R-22 refrigerant make it an essential and reliable choice for air conditioning systems requiring precise refrigerant control.
