The invention provides a three-way hydraulic valve, and relates to the technical field of hydraulic pressure. The three-way hydraulic valve comprises a main valve body, two main valve element modules and two guide valve body modules. The main valve body comprises two main oil holes intersected by an acute angle to form a public oil cavity; and each main oil hole is a straight hole penetrating through the main valve body. The two main valve element modules are correspondingly inserted in two main valve element holes. The two guide valve body modules are correspondingly arranged on the end surfaces of the two main valve element holes. The main valve element modules and the main valve element holes form valve line sealing structures. The three-way hydraulic valve is used for conducting and/or stopping high-pressure oil flowing in the main oil holes from a direction forming acute angles with the main valve element holes. The three-way hydraulic valve is used for conducting and/or stopping the high-pressure oil flowing in the main oil holes from the direction forming the acute angles with the main valve element holes; when when main valve elements are located in a conduction working state, the high-pressure oil flowing through the main oil holes needs no turning, so that the pressure loss is reduced. The main valve elements can guarantee no leakage of hydraulic oil in a stop working state.
