The Bosch Rexroth LC25DB40D7X/-004 (R900919723) is a high-performance, hydraulically actuated industrial hydraulic valve designed for reliable pressure relief to a set value. This seat valve operates as a pilot-operated spool with symbol A B, ensuring maximum pressure efficiency in its operation. It belongs to the product group ID and is equipped with numerous ports, conforming to a standardized size and max flow rate specifications. The type of connection utilized by this model is a cartridge valve, which follows the ISO connection diagram standards. This way cartridge valve is intended for pressure functions and can be installed into receiving holes standardized according to DIN ISO standards, secured with a control cover. The integrated pilot control valve allows for manual or electrically proportional pressure adjustment either within the control cover or mounted atop it following DIN standards. By combining these cartridge valves with control covers, different pressure functions can be executed effectively. For pressure relief applications, the LC25DB40D7X/-004 operates as a seat valve without an effective area at port B, directing effective pressure at port A through the pilot oil supply orifice to the spring side of the element. The spool remains closed under spring force until the set pressure is reached, at which point it opens to limit the pressure according to its characteristics. In terms of pressure reducing functions, this model can also be used in conjunction with other components like a control cover with a pressure-reducing pilot control valve for applications requiring opening characteristics and secondary side pressure discharge capabilities. Moreover, this versatile valve also supports pressure sequencing functions that enable connection of secondary systems dependent on reaching set pressures. Circuit examples provided illustrate how this model can be used for unloading low-pressure systems or connecting secondary systems based on specific pressures. The Bosch Rexroth LC25DB40D7X/-004 comes with NBR seals compatible with various hydraulic fluids like HL, HLP, HLPD, HVLP, HVLPD, and HFC. Its robust design promises reliability across various applications without compromising on performance or efficiency.
