The Bosch Rexroth LFA25GWA-7X/P12 (R900969203) is a high-precision way cartridge valve engineered for integration into compact block designs. This valve leverages a standardized receiving hole compliant with ISO specifications, ensuring seamless installation into control blocks. The included cover serves not only as a closure but also as a conduit for pilot control valves that manage the power section's connectivity to ports A and B. This versatile component supports various functions, including pressure regulation, directional control, and flow throttling, which can be customized through the use of appropriate pilot control valves. It offers an efficient solution by allowing size adjustments to match different flow rates for individual actuator paths. The potential for multi-functional use makes this valve particularly cost-effective. The LFA25GWA-7X/P12 consists of two primary parts: the control cover and the installation kit. The control cover houses control bores and may include additional features such as stroke limitation, hydraulically controlled directional seat valves, or shuttle valves tailored to specific overall functions. Electrically operated directional spool or seat valves can also be fitted onto the control cover if required. The installation kit comprises components such as a bushing, ring (up to a certain size), valve poppet (with or without damping nose), and closing spring. Functionality of this way cartridge valve is pressure-dependent, enabling three distinct pressurized areas (A1, A2, A3) crucial for operation. These areas facilitate opening and closing actions with varying area ratios influencing cracking pressures and flow dynamics. When energized by pilot oil discharge from channel B or an external pilot oil supply, the valve can block channel A without any leakage. Overall, the Bosch Rexroth LFA25GWA-7X/P12 offers robust performance in hydraulic systems requiring precise manipulation of fluid dynamics within a compact design envelope.
