This utility model discloses a multi-way valve for a pre-pressure compensator, including a valve body and a drive assembly. The valve body has a main valve chamber inside, and a main valve core is located inside the main valve chamber. The main valve core can slide along the main valve chamber via the drive assembly. The valve body surface has ports P, T, A, and B, all of which are connected to the main valve chamber. A pressure compensator is also located inside the valve body. Port P is connected to the main valve chamber through the oil inlet of the pressure compensator, and port T is connected to the oil return of the pressure compensator. The main valve core slides to switch the connection states of ports P and T with ports A and B, achieving mechanical interlocking of oil circuit on / off. This utility model provides a multi-way valve for a pre-pressure compensator. The drive assembly moves and switches the valve core, cooperating with the pre-compensator to compensate for the pressure difference in the working circuit, thereby maintaining a constant pressure difference between ports P and T of the valve body.
