The Danfoss Orifice Expansion Valve is a simple, fixed-type pressure reduction device with no moving parts for flow adjustment.
It serves as the point where high-pressure liquid refrigerant from the condenser expands into a mixture of vapor and liquid (flash gas) before entering the evaporator.
The refrigerant flow rate is precisely determined by the size of the orifice, which is specifically designed for the system’s cooling capacity requirements.
