The Bosch Rexroth LC 25 B40E7X/-010 (R900770702) is a high-performance way cartridge valve designed for seamless integration into compact block systems. The valve's power section, with connections A and B, fits into a standardized receiving hole and is secured with a cover that also serves as the conduit for pilot control valves. This design allows the LC 25 B40E7X/-010 to be used for various functions including pressure, directional, and throttle control by pairing it with appropriate pilot valves. The cartridge valve's modular nature permits cost-effective solutions by tailoring the size to match different flow rates required by an actuator's individual ways. The versatility of the LC 25 B40E7X/-010 extends to its ability to handle multiple functions simultaneously, further enhancing its economic value. Comprising a control cover and installation kit, this valve features control bores within the cover and may include additional functionalities such as stroke limitation, hydraulically controlled directional seat valves, or shuttle valves depending on the overall function needed. Electrically operated directional spool or seat valves can also be accommodated on the control cover. The installation kit includes essential components like a bushing, ring (up to NG), valve poppet (with or without damping nose), and closing spring. The operation of this way cartridge valve is pressure-dependent, creating three distinct pressurized areas (A1, A2, A3) crucial for its function. Area ratios between these zones influence the valve's behavior under different pressures leading to various cracking pressures based on whether damping noses are used or not. In essence, areas A1 and A2 are active in opening the valve while area A3 alongside the spring assists in closing it. The resulting force from these areas determines the spool position within the way cartridge valve. Designed for bidirectional flow from A to B or vice versa, this model ensures that when area A3 is pressurized through pilot oil discharge from channel B or external supply, channel A remains blocked without any leakage.
