How a TXV/TEV works | Thermostatic Expansion Valve
Thermostatic expansion valves (often called TXVs and sometimes TEVs) adjust the flow of liquid refrigerant to the evaporator by controlling the superheat. The superheat can be manually adjusted to optimize the efficiency of a cooling system.
How an EVRA works | Industrial Refrigeration Solenoid Valve
EVRAs are solenoid valves used exclusively in industrial refrigeration settings. They close off the flow of refrigerant, both liquid and hot gas. They are frequently used to cut off the liquid supply to the evaporator and open for hot gas defrosting.
How an AKV works | Electrically Operated Expansion Valve
An AKV is an electric expansion valve (EEV)—often referred to as an electronic expansion valve (also EEV). It uses pulses governed by an electronic controller to regulate the flow of refrigerant to the evaporator.
An AKV valve is, in effect, a solenoid valve and works as such, so no extra solenoid valve installation is needed.
