Various control methods: manual, pneumatic, electro-hydraulic, electrical, electromagnetic, one-control-two-handle flexible shaft control and remote control, etc., which can be selected according to different usage scenarios and operation requirements.
SD8 series Sectional Valve are widely used in hydraulic systems of engineering machinery, sanitation machinery, mining machinery and other machinery.
OPERATION：
By changing the position of the valve core, the path of the hydraulic oil flow is changed, thereby controlling the change of oil pressure, flow or direction, and realizing the motion control of multiple actuators in the hydraulic system, such as controlling the movement of the excavator's bucket, boom, dipper and other components.
