The YZM4 series multi-way valve is primarily suitable for variable pump systems in mining machinery, as well as similar construction and agricultural machinery. This multi-way valve is load-sensitive, meaning its output flow is independent of load changes, providing excellent control stability.

Inlet Section: No flow divider valve spool is installed, mainly used in variable pump systems; an internal priority valve is integrated, which can provide flow to other systems through port P1 to ensure that the steering function receives priority flow distribution, achieving safe, accurate and efficient control; it is also equipped with a high-pressure relief valve to limit the maximum system pressure.

Working Section: Primarily used for steering control, employing a hydraulic control method. The working port has a secondary pressure-limiting relief valve to adjust the maximum pressure limit. The maximum output flow is adjusted by regulating the valve spool's stroke limit.

Tail Section: Equipped with an inlet port, allowing for dual-pump oil intake.
