The Working Principle and Application of the Manual Directional Valve for Hydraulic Stations

Hydraulic station manual directional valve is a type of valve used to control the direction of fluid in a hydraulic system. It can be manually operated to direct the fluid to different hydraulic components or circuits, achieving control and operation of the hydraulic system. Manual directional valve typically includes a valve body and a handle. The handle is used for manual operation of the valve, changing the valve's position and flow direction. Inside the valve body, there are one or more fluid passages and valves. When the handle moves, the valve also moves, changing the direction of the fluid flow.

Manual directional valve is widely used in hydraulic systems. For example, in hydraulic machine tools, hydraulic machinery, hydraulic cranes, and other equipment, manual Directional valve can be used to switch different operational positions, control different hydraulic components, and control the forward and backward stroke of hydraulic cylinders, among other functions. Manual Directional valve is simple to use, reliable, and flexible in operation, making it an essential component in hydraulic systems.

Manual Directional Valve Working Principle

The working principle of the hydraulic station manual directional valve is similar to that of ordinary hydraulic valves, which control fluid direction by changing the valve position. The valves of manual directional valve are usually controlled by a handle, and the position of the handle determines the position of the valve, thus controlling the fluid's direction. Specifically, when the handle is in the closed position, fluid cannot flow through the valve passage. When the handle is moved to the open position, the valve opens, allowing fluid to flow through the valve passage. Different handle positions result in different valve positions and fluid directions.

Manual directional valve valves come in various structures, such as sliding valves, ball valves, and butterfly valves. Different valve structures are suitable for different applications, achieving different flow, pressure, and direction control. In summary, manual directional valve can be operated via a handle, changing the valve position, thereby controlling the fluid's direction and pressure to achieve control and operation of the hydraulic system.
