The reel circuit uses 1 solenoid to lower the reel, but 2 to raise it.
One solenoid opens the reel passage, another closes the pump return flow passage through the valve stack.
When you lower the reel, the reel solenoid only opens , dumping fluid into the open return flow passage and gravity lowers the reel.
To raise the reel the reel solenoid opens and the return passage solenoid closes, trapping pump pressure in the return passage. Thus high pressure fluid is pushed into the reel passage which extends the cylinders. When you release the reel switch from the "up" position, the reel solenoid closes, locking the reel in position, and the return port opens allowing all pump pressure / flow to return to the hyd tank.
