How a TEV Works
A Thermostatic Expansion Valve automatically regulates the flow of refrigerant into the evaporator coil based on the superheat of the refrigerant leaving the evaporator. By maintaining optimal superheat, the TEV ensures the evaporator is fully utilized while preventing liquid refrigerant from reaching the compressor — maximizing system efficiency and protecting critical components.
Typical Applications
- Commercial refrigeration systems
- Industrial HVAC and process cooling equipment
- Chiller and condensing unit installations
- Larger-capacity evaporator coil assemblies
