Hydraulic Balance Valve Cbbd-Xmn Excavator Hydraulic Cylinder Spool

Hydraulic valve as an important part of the hydraulic system, its role is to control the fluid flow direction, pressure and flow in the hydraulic system. The working principle of the hydraulic valve is based on the principles of fluid mechanics and mechanics, and the size and position of the valve port are changed by the movement of the valve core, so as to achieve accurate control of the fluid in the hydraulic system. There are many types of hydraulic valves, including direction control valves, pressure control valves and flow control valves, and each valve plays an indispensable role in the hydraulic system. The directional control valve is responsible for controlling the flow of fluid to ensure that the hydraulic system can work in accordance with the preset path; The pressure control valve is responsible for adjusting the pressure in the system to ensure the stability and safety of the system; The flow control valve controls the operating speed of the hydraulic system by adjusting the flow rate of the fluid.
