What is Multiple Directional Control Valve?

Multiple Directional Control Valve is a commonly used control component in hydraulic systems, used to control the distribution of hydraulic flow direction and flow. There is a close relationship between it and the hydraulic cylinder, which controls the movement of the hydraulic cylinder by controlling the inlet and outlet of hydraulic fluid.
Arbeitsweise:
A multi way directional valve usually consists of one or more valve cores and a valve body, which can move inside the valve body to change the connection status of the hydraulic channel. It has multiple channels, each with different inlet and outlet connections to the hydraulic source, hydraulic cylinder, and oil tank. By controlling the position of the valve core, different channels can be opened or closed to control the flow direction and flow rate of hydraulic fluid.

When the valve core is in different positions, the multi way directional valve can achieve the following basic working modes:

1. 2/2-way valve: The valve core has two positions that can switch the channels of hydraulic fluid, allowing hydraulic fluid to enter the hydraulic cylinder from one channel and connect the other channel to the oil tank, achieving one-way movement of the hydraulic cylinder.
2. 3/2-way valve: The valve core has three positions that can switch the channels of hydraulic fluid, allowing hydraulic fluid to enter the hydraulic cylinder from one channel and close the other channel to achieve one-way movement of the hydraulic cylinder. The third position connects the hydraulic fluid in the hydraulic cylinder to the oil tank, achieving the return oil of the hydraulic cylinder.
3. 4/3-way valve: The valve core has four positions and can switch the channels of hydraulic fluid, allowing hydraulic fluid to enter the hydraulic cylinder from different channels, achieving bidirectional movement of the hydraulic cylinder. It is also possible to connect the hydraulic fluid in the hydraulic cylinder to the oil tank to achieve oil return of the hydraulic cylinder.

By controlling the operating lever, solenoid valve, hydraulic proportional valve, etc. of the multi way directional valve, the position of the valve core can be accurately controlled, thereby achieving precise control of the movement speed, direction, and stop of the hydraulic cylinder.
In short, the multi way directional valve is an important control component in the hydraulic system, which closely cooperates with the hydraulic cylinder to achieve motion control of the hydraulic cylinder by controlling the flow direction and flow rate of the hydraulic fluid.

Applications of Multiple Directional Control Valve

Multi way directional valves have various applications in hydraulic systems. In addition to cooperating with hydraulic cylinders to achieve motion control, the following are some common applications of multi way directional valves in hydraulic systems:

• Hydraulic motor control: The multi way directional valve can be used to control the start stop, steering, and speed adjustment of the hydraulic motor. By switching the channels of hydraulic fluid, the steering and output torque of the hydraulic motor can be controlled, thereby achieving motion control of the driving mechanical equipment.
• Hydraulic pump control: Multiple directional valves can be used to control the start/stop and flow regulation of hydraulic pumps. By controlling the inlet and outlet channels of hydraulic fluid, the working state and output flow rate of the hydraulic pump can be controlled to meet the requirements of the hydraulic system.
• Flow direction control of hydraulic system: Multi way directional valves can be used to control the flow direction of hydraulic fluid in the hydraulic system, such as switching the working mode of the hydraulic system, selecting the working circuit, etc. By switching different channels, it is possible to achieve reasonable distribution and flow control of hydraulic fluid in the hydraulic system.
• Pressure control of hydraulic system: Multi way directional valves can be used to achieve pressure control functions in hydraulic systems, such as setting safety valves, adjusting system pressure, etc. By controlling the flow direction and flow rate of hydraulic fluid, the working pressure in the hydraulic system can be controlled to ensure the safe and stable operation of the system.

In summary, the multi way directional valve has a wide range of applications in hydraulic systems. It can not only cooperate with hydraulic cylinders to achieve motion control, but also be used in various aspects such as hydraulic motor control, hydraulic pump control, flow control, and pressure control to meet the various functions and requirements of hydraulic systems.
