Back seating a two-way service valve results in which condition?

Explanation:
Back seating a two-way service valve keeps the service port accessible while the system can continue to operate normally. In this position, the main flow path remains open and the service port is open to the refrigerant, so you can attach gauges and read pressure without interrupting system flow. This is why the result is an open service port with normal system flow. It’s not about stopping flow or sealing off the service port, which would require a different valve position.
