The Bosch Rexroth LC63DR40E7X/V (R900962622) is a high-performance way cartridge valve designed for pressure functions, including pressure reducing applications. This pilot-operated valve comes in both seat and spool designs and is built to fit standardized receiving holes according to DIN ISO, ensuring easy installation and compatibility with various systems. It features a power section that operates as a cartridge valve and is securely sealed with a control cover. The LC63DR40E7X/V boasts an integrated pilot control valve that can be manually or electrically adjusted for proportional pressure, adding to its versatility. The control cover can either house the pilot control valve directly or support an additional pilot valve mounted on top, adhering to mounting dimensions set by DIN standards. This flexibility allows for the realization of different pressure functions when combined with appropriate control covers. For the pressure reducing function, this model operates as a spool valve without an area difference at port B, meaning there are no effective areas at this port. It utilizes cover types similar to those used in the pressure relief function (type LFA..DB...), ensuring reliable performance. The pressure at port A is regulated through the pilot oil supply orifice leading to the spring side of the spool. Under normal conditions and within set pressures, the spool remains balanced by spring force allowing free flow from port B to A. Once the system reaches the pre-set pressure limit, the spool closes, effectively reducing the pressure at port A according to its specific pressure-flow characteristics. The LC63DR40E7X/V is designed to handle maximum flow rates efficiently while maintaining stable operation under various conditions, making it an essential component for hydraulic systems requiring precise pressure management.
