In this video we cover how the TXV bypasses in the heat pump cycle.
We cover internal and external check valves plus the bi-flow Txv that meters in either direction.
Special thanks to JD Kelly @ Student_of_HVAC for these graphics!
We do not cover how the normal operation of the TXV as that has been discussed previously here:

Heat pumps typically have 2 metering devices but only 1 is used at a time.
in this video we discuss how TXV bypass when not in use. we also discuss how a single TXV can be used to meter in either direction.
