Background

‌ Hydraulic valves control the pressure, flow and direction ‌ in the hydraulic system by regulating the passage of fluid. The hydraulic valve mainly comprises a valve core, a valve body, a control element, a spring and other parts. When the hydraulic valve is in a closed state, the valve core can be tightly attached to the valve seat, and fluid is prevented from passing through. When opening is needed, the control element applies force to move the valve core, so that a channel in the valve body is opened, and pressure oil flows into the outlet from the inlet. The position of the valve core determines the pressure and flow rate of the fluid, and the hydraulic valve can also change the position of the valve core according to the signal of the control element, so that the direction and the pressure of the hydraulic system are controlled.

Hydraulic valves play a vital role in hydraulic systems, and they meet the demands of the actuators by controlling the direction, pressure and flow of the fluid.
