How does a Logic Valve control hydraulic flow and pressure?

Logic Valve plays a vital role in hydraulic systems, especially in the control of flow and pressure. It helps the hydraulic system to achieve efficient and stable operation through precise logic control combined with the flow characteristics of hydraulic fluid. Flow and pressure control in hydraulic systems are the core of system design, and Logic Valve can accurately adjust these two key parameters through its complex internal mechanism and control method, thereby ensuring the safety, stability and efficiency of the system.

Logic Valve controls flow through its internal multiple functional valve cores, springs and adjustment devices. Its design can automatically adjust the valve opening according to the flow demand in the hydraulic system, thereby changing the channel size of the fluid and controlling the flow of the fluid. When the pressure in the hydraulic system changes, the logic valve will limit or increase the flow by adjusting the valve core position according to the preset flow range. This control mechanism not only ensures the stability of the flow in the system, but also adjusts according to changes in load requirements. For example, when the load demand increases, the flow control valve can automatically increase the flow to ensure that the system can provide sufficient energy supply. On the contrary, when the load is reduced, the flow control valve will reduce the flow, thereby avoiding energy waste and reduced system efficiency.

In terms of pressure control, Logic Valve also plays a vital role. It can sense the pressure changes in the hydraulic system in real time and take corresponding measures when the pressure reaches the set safety value to prevent the pressure from exceeding the system's tolerance range. When the system pressure rises to a critical point, the Logic Valve automatically releases part of the pressure by adjusting its internal valve core or spring system, or closes the fluid channel to keep the pressure inside the system stable. This pressure control method is one of the most common protection measures in hydraulic systems. It can effectively prevent system damage or equipment failure caused by excessive pressure. More complex logic valves can also adjust pressure under different working conditions by adjusting different pressure levels and spring tensions to ensure that the hydraulic system can operate stably under various load conditions.

Logic Valve can not only control flow or pressure alone, but also combine pressure and flow control through a linkage mechanism, so that the system can operate efficiently under more complex working conditions. The linkage control between flow and pressure makes the logic valve more flexible. When the pressure of the hydraulic system changes, the Logic Valve can adjust the flow according to the preset control logic to adapt to the load requirements of the system. For example, in some industrial applications, as the pressure increases, the flow of the hydraulic system may decrease. Logic Valve can ensure that this change does not lead to a decrease in system performance through real-time monitoring and adjustment. Through this linkage control, Logic Valve can ensure that the hydraulic system is always in the best operating state in a dynamically changing working environment, avoiding potential failures caused by mismatching pressure and flow.
