The Bosch Rexroth LFA63WEMA-7X/P20T20 (R901438106) is a sophisticated way cartridge valve designed for streamlined integration into compact block systems. This valve is engineered to facilitate pressure, directional, and throttle functions or a combination thereof when controlled by corresponding pilot valves. Its modular nature allows for efficient solutions through customization of flow sizes to meet the specific requirements of each actuator's pathways. The LFA63WEMA-7X/P20T20 comprises a control cover and an installation kit. The control cover hosts the control bores and can include additional features like stroke limitation, hydraulically controlled directional seat valves, or shuttle valves depending on the desired overall functionality. For electrical operation, directional spool or seat valves may be attached to the control cover. The installation kit contains essential components such as a bushing, ring (applicable up to NG), valve poppet (with optional damping nose), and a closing spring. This way cartridge valve operates based on pressure with three distinct pressurized areas (A1, A2, A3) crucial for its function. The area ratios between these zones determine the spool position by balancing opening forces against closing forces exerted by the spring. With different area ratios available (e.g., 2:1 or 3:1), this valve offers versatility in controlling flow direction either from A to B or B to A with minimal leakage. The Bosch Rexroth LFA63WEMA-7X/P20T20 is characterized by its ability to block channel A without leakage when area A3 is pressurized either by pilot oil discharge from channel B or an external pilot oil supply. It's designed for applications that require precise hydraulic control within a compact system footprint, ensuring reliability and effective performance in various hydraulic systems without sacrificing space efficiency.
