    When refrigerant flow meets a check valve in the allowed direction it will take the route of least resistance and go through the check valve and ignore the TXV. There are TXVs that have this check valve function built right into the valve itself. The Bi-Flow filter/drier works in a similar manner. Inside a bi-flo drier there are check valves which ensure that refrigerant flow goes through the drier core in the same direction
