    Depends on the valve and hydraulic ram. Most rams on plows are one way. So when the ram lifts, the pressure is routed in. And when it collapses, the loop is open back to the reservoir. Depending on what kind of valve you have, this can be a maintained open loop or non-maintained. The float feature is just a maintain open loop (stuck in the down position) and found and industrial truck suppliers.

    If the valve is cable operated or located in the cab of the truck and lever operated, it is easy to replace. If it is solenoid operated it may be more difficult.

    There is a valve that can be installed so the down position becomes a float position. I can not remember the name of the valve but it doesn't cost more than 20 dollars. On a central system it is needed for both the angle cyclinders, or the valve body must containe a pressure relief function, or you will bend and crush angle cylinders.
