EspañolDirectional Control Valve and ordinary valves play different roles in hydraulic systems, and there are significant differences between their working principles, operating methods, structural designs and application scenarios. Directional control valves are mainly used in hydraulic systems. Their main function is to control the flow direction of liquid, thereby achieving precise control of the movement direction and speed of hydraulic actuators (such as hydraulic cylinders or hydraulic motors). Ordinary valves are usually used to control the flow and pressure of fluids or prevent fluid flow. Their functions are relatively simple and are mainly used in pipeline systems and liquid handling systems in various industrial fields.
Directional control valves have a variety of operating modes, such as manual control levers, solenoid valves, etc., which enable the directional control valve to be operated remotely or on-site, and to quickly switch the flow direction in a short time. This flexible operation method makes directional control valves have wide application value in hydraulic systems. The operation of ordinary valves is relatively simple, usually through manual rotation, push and pull, or electric actuators. The operation process is more intuitive and direct, but it relatively lacks the ability to remotely control.
There are also significant differences in application scenarios between directional control valves and ordinary valves. Directional control valves are mainly used in engineering machinery, ships, wind turbines and other fields in hydraulic systems to achieve precise control of hydraulic actuators. Ordinary valves are widely used in pipeline systems, liquid handling systems, etc. in various industrial fields to control the flow and pressure of fluids or prevent fluid flow. This differentiated application scenario gives directional control valves and ordinary valves different advantages and values in different fields.
