Lennox 12J20 45-Ton AC Thermostatic Expansion Valve Kit R410A

The Lennox 12J20 AC Thermostatic Expansion Valve Kit functions as a necessary element for commercial HVAC systems. The part controls refrigerant flow into the evaporator coil with precision to achieve both High performance and maximum efficiency. The valve maintains stable temperatures by performing essential pressure control which protects the compressor from harm. The 45-ton capacity valve operates with R410A refrigerant while accommodating various applications from commercial buildings to retail stores and industrial facilities. This expansion valve measures both refrigerant temperature and pressure as the fluid enters the evaporator. The part uses sensor readings to modify refrigerant flow automatically for temperature control.
