The working principle of hydraulic valve is based on fluid mechanics and control theory, and its core lies in the relative movement between the valve core and the valve body. When external control signals (such as electrical signals, mechanical signals or hydraulic signals) act on the spool, the spool will overcome spring force, friction and other resistance, resulting in displacement, thereby changing the size of the valve port or the opening and closing state. This change directly affects the flow path, pressure and flow of hydraulic oil, and then realizes the control of the hydraulic system. For example, in the direction valve, the rotation or translation of the spool can change the flow direction of the oil, so that the actuator can achieve forward or reverse movement; In a pressure valve, the opening or closing of the spool is used to regulate the pressure of the system to ensure that it operates within a safe range.
