SANY Spare Parts 62001539163 Excavator KPM Hydraulic Main Control Valve

The function of hydraulic control valve (referred to as hydraulic valve) in the hydraulic system is to control and regulate the flow direction, pressure, and flow rate of oil in the hydraulic system, so that the actuator and its driven working mechanism can obtain the required movement direction, thrust (torque), and movement speed (speed).

No hydraulic system, no matter how simple, cannot lack hydraulic valves; Hydraulic mechanical equipment with the same process purpose can form various hydraulic system schemes with completely different oil circuit structures through different combinations of hydraulic valves. Therefore, hydraulic valves are the most diverse, widely used, and active part (component) in hydraulic technology; The ability of a newly designed or operating hydraulic system to operate normally and reliably according to established requirements largely depends on the performance and reasonable parameter matching of various hydraulic systems used.
