The Bosch Rexroth LC50DR40E7X/ (R900938052) is a high-performance industrial hydraulic valve designed for reliable pressure reduction to a predetermined setting value. This hydraulically actuated spool valve, featuring a B A spool symbol, is capable of handling a maximum pressure as specified by its product group ID. It is equipped with a number of ports corresponding to its size and can manage a maximum flow rate that ensures efficient operation within hydraulic systems. The LC50DR40E7X/ valve is of the cartridge type and adheres to DIN ISO standards for installation into standardized receiving holes, which are then sealed with a control cover. The integrated pilot control valve allows for manual or electrically proportional pressure adjustments and conforms to mounting dimensions set by DIN 58367. This model's versatility is highlighted by its ability to combine with control covers to achieve various pressure functions. Particularly, it excels in the pressure reducing function with a default rest position that remains open. Designed without an area difference at port B, this spool valve ensures no effective areas interfere at this port, promoting smooth operation. For the pilot control valve, the same cover types used for pressure relief functions are applicable, specifically type LFA..DB.... The system's dynamics allow the effective pressure at port A to be directed through the pilot oil supply orifice to the spring side of the spool. Below the performance limit and predetermined pressure set on the pilot control valve, the spool remains open due to spring force allowing free flow from port B to port A. When reaching the set pressure point, the spool closes, thereby reducing the pressure at port A according to its characteristic curve. The LC50DR40E7X/ utilizes NBR seals and is compatible with hydraulic fluids such as HL, HLP, HLPD, HVLP, HVLPD, and HFC types. It also features an unspecified weight that contributes to its overall robustness in industrial applications.
