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.
