An automatic variable device controlling the flow of liquid refrigerant.
An expansion device that removes pressure from the refrigerant as it flows into the evaporator and controls the flow rate in relation to evaporator temperature.
A refrigerant metering device that maintains a constant evaporator temperature by monitoring suction vapor superheat; also called a thermal expansion valve.
A valve used in refrigeration systems to control the superheat in an evaporator by metering the correct refrigerant flow to the evaporator.
A device that creates a constant evaporator temperature.
A thermostatic expansion valve (TXV) is precision device used to meter the flow of liquid refrigerant entering the evaporator at a rate that matches the amount of refrigerant being boiled off in the evaporator.
a component regulating the rate of refrigerant flow into evaporator as governed by evaporator outlet pipe temperatures sensed by the sensing bulb.
A component in the refrigeration system that controls the rate of refrigerant flow into the evaporator. This is done by means of a temperature sensing bulb that causes the valve to open or close in response to temperature changes in the evaporator.
