Hi & welcome to the forum Its quite common to have the valve block configured with relief valves for more than one circuit, so the dipper may be group with a track or, the slew with the bucket for example, and it may be the case that you have a faulty relief valve that is either opening too easily due to a broken spring or not closing properly for the same reason, or that there is a foreign body causing it to stick, you would really need to identify which relief valve is which, then pull it out and have a look for problems with it, or it may be that it just needs adjusted to operate at the correct pressure.
