A part of an air-conditioning system, located between the condenser and the evaporator, that regulates the flow of liquid refrigerant to the vaporator. If cooling needs are low, the valve is almost closed; as additional cooling is required, the valve opens wider so that more liquid refrigerant flows to the evaporator.
a thermostatically controlled valve, or metering device, for controlling the boiling point and flow of refrigerant to the cooling element (evaporator)
A device in a refrigerating system that reduces and maintains a pressure difference between the "high side" and "low side" operated by pressure.
See " THERMOSTATIC EXPANSION VALVE"
This device controls the temperature and pressure of the refrigerant preventing damage to the compressor.
Variable orifice that forces refrigerant to expand and take on heat. This makes the refrigerant very cold.
A refrigerant-metering valve with a pressure or temperature controlled orifice.
The device that reduces the pressure of liquid refrigerant thereby cooling it before it enters the evaporator coil in a heat pump.
Is one type of metering device in refrigerating system, which reduces the pressure from the high side to the low side and is operated by pressure.
A device in refrigerating system which maintains a pressure difference between the high side and low side and is operated by pressure.
Same as TXV valve, a control device that meters the amount of refrigerant to the evaporator to regulate cooling.
A thermostatically controlled valve, which controls the liquid refrigerant as it passes through, and cooling it to the temperature in the evaporator. The diaphragm, which seals the tube to the chamber on the expansion valve, is attached on the valve stem, which is pushed toward closed by a spring. When the temperature of the line rises, the refrigerant in the bulb, tube and upper chamber allows the spring to open the expansion valve. More refrigerant is allowed into the evaporator once the expansion valve is opened. This valve works in response to the cooling load demand on the evaporator.
