The Bosch Rexroth LC40DB20E7X/V (R900957978) is a sophisticated cartridge valve designed for pressure functions in hydraulic systems. This pilot-operated valve, whether in seat or spool design, is engineered to fit standardized receiving holes according to DIN ISO norms and is sealed with a control cover. It incorporates a pilot control valve that can be adjusted manually or through an electrically proportional system, either integrated into the control cover or mounted on it following DIN specifications. The LC40DB20E7X/V enables the realization of various pressure functions by combining cartridge valves with appropriate control covers. For instance, its pressure relief function operates as a seat valve and utilizes a spring mechanism to maintain closure until the set pressure is reached, at which point it opens to limit the pressure at port A based on its characteristics. Similarly, when configured for pressure reducing functions with opening characteristics, this model uses a combination of a pressure limitation cartridge valve and a control cover equipped with a pressure-reducing pilot control valve. This arrangement allows for controlled flow from port A to port B and manages any potential secondary side pressure increases by discharging them back to the tank. Moreover, this model can be used for pressure sequencing functions that enable the connection of secondary systems based on preset pressures. The switching pressures are adjustable via an integrated pilot control valve in the control cover. The LC40DB20E7X/V also provides circuit examples such as one for unloading low-pressure systems upon reaching certain pressures and another for connecting secondary systems only after primary system pressures meet specified values. This versatile component has been engineered for maximum flow rates as per its series specifications and offers reliable performance in controlling hydraulic pressures across different applications.
