The Bosch Rexroth LFA40H2-7X/FDR (R900938125) is a sophisticated way cartridge valve designed for seamless integration into compact block systems. This product is engineered for versatility, supporting pressure, directional, and throttle functions or their combinations. The innovative design ensures efficient application by allowing the size adjustment to match various flow requirements of an actuator's individual ways. This cost-effective solution leverages the use of power sections for multiple functions, enhancing operational efficiency. The LFA40H2-7X/FDR consists of a control cover that houses control bores and may include additional features such as stroke limitation function, hydraulically controlled directional seat valve, or a shuttle valve depending on the necessary overall function. For further customization, electrically operated directional spool or seat valves can be installed on the control cover. The installation kit includes essential components like a bushing, ring (applicable only up to NG), valve poppet with an option for damping nose or without it, and a closing spring. This way cartridge valve operates based on pressure-dependency creating three critical pressurized areas labeled A1, A2, and A3. The area ratios between these zones determine the spool position by balancing opening forces against closing forces exerted by the spring. By controlling area A3 through pilot oil discharge from channel B or an external pilot oil supply, channel A can be blocked without leakage. Additionally equipped with a remote control port and stroke limitation feature, this product ensures precise control over hydraulic systems with minimal leakage during operation. It allows fluid transfer either from A to B or B to A when pressurizing area A3 under specific conditions. The Bosch Rexroth LFA40H2-7X/FDR is tailored for high-performance hydraulic applications requiring reliable and efficient flow regulation within compact spaces.
