Hi, there are relief valves on the MCV, see the photo below: 1) Bottom right plug/ System Relief Valve is for 3pt and remotes set to 2500 PSI, depending how your loader is connected this should be the relief valve that protects the pump. 2) Middle left plug/ Power steering relief valve set to 1500 PSI 3) Top center plug/ Oil Cooler bypass valve set to 250 to 275 PSI 4) Top right plug/ PTO clutch pressure valve set to 250 to 275 PSI.
Most loaders that have their own hydraulic valves mount on the loader frame also have an inbuild relief valve see photo #2 below with the RED circle around the valve body relief valve. This cover will be under spring tension controlling the relief valve setting, typically this relief valve should be set to about 200 PSI less than the 2500 PSI on relief #1.
