Logic cartridge valves serve a crucial role in hydraulic systems by providing additional control and logic functions. These valves work alongside other hydraulic components to achieve specific system requirements. Logic cartridge valves enable pressure control by regulating pressure levels, ensuring constant pressure or limiting maximum pressure to protect system components. They also offer flow control capabilities, regulating flow rates, restricting or enabling flow in specific directions or conditions. Moreover, they facilitate sequence control, dictating the order or timing of hydraulic operations. Additionally, logic cartridge valves can control the direction of fluid flow and incorporate various logical functions, such as AND, OR, NOT, delay, and latching, to perform complex operations based on specific conditions or inputs. Overall, logic cartridge valves enhance the control capabilities of hydraulic systems, enabling precise control and sophisticated functionality.
