Thats interesting to know that they are the same. I do have a relief valve and it's set at about 28 bar. At 20 bar this machine doesn't have a lot of power but the valves do turn much easier. I would like to be able to dig firm ground with it so I think 25-30 bar is necessary. Do you know the diameter of the valve?

Thanks Reg
