The gate valve with the green handle are prone to failing in the closed position. The handle will still operate but the gate will remain in the closed position. This may have happened to yours. I never try to shut these valves off for this reason. Drain the system again and remove the valve and see if the gate in the valve is open. I hope this helps.
