Stam, you are very right.
I am not very expert of Hydraulics but spent hours with this valve in last 2 weeks. As per my Learning on this valve; it does not need any electrical connection for Lifting, if there is pressure POD will actuate because of excessive pressure and direct the pressure to Lifting rams. If we remove all coils from the valve it will still be able to lift. It doesn't happen in other machine.
It needs a Pilot pressure from AUX Coils to retain it to the AUX function position. If pilot pressure is there and POD is stuck or not working properly it will keep lifting the Lift rams.
Please correct me if it works differently.
