To check a reversing valve, first ensure the system is powered off and depressurized for safety. Then, inspect the valve for any visible signs of damage or leaks. You can manually operate the valve by applying power to the solenoid, observing if it shifts positions correctly. Additionally, use a multimeter to test the solenoid for continuity, confirming that it is functioning properly.
the reversing valve is what actually changes the refrigeration cycle from heat to cool. the reversing valve receives its signal from the thermostat.
first you have to turn the valve and see if it was just in a wrong position
sounds like t stat is programmed wrong, reversing valve coil is bad or reversing valve is stuck.

To measure voltage at the reversing valve, first ensure the system is powered on and safe to work with. Use a multimeter set to the AC voltage setting, and carefully connect the probes to the terminals of the reversing valve. Make sure to follow safety precautions to avoid electrical shock, and take note of the voltage reading, which indicates the electrical supply to the valve. If the voltage is not within the expected range, further troubleshooting may be necessary.

A dual check valve is similar to a double check valve in that it is a mechanical backflow preventer consisting of two independently acting, spring-loaded check valve.

Heat pumps have a reversing valve in the outside unit. You are hearing a balance of refrigerant pressures when the reversing is energized or de-energized.
There is no difference between check valve and NRV, both are same

A check valve allows for flow in one direction and a gate valve is used for positive shut off and a globe valve is used for throttling
