The Bosch Rexroth LC25B00E7X/V (R900929381) is a high-performance industrial hydraulic valve, specifically designed for reliable switching of oil flow direction in accordance with its spool symbol BE. This unidirectional, hydraulically actuated spool type valve is part of the cartridge valve series, facilitating compact block design integration. The LC25B00E7X/V valve excels in applications requiring precise control of pressure, directional, and throttle functions or combinations thereof. The valve's construction allows for efficient solutions by matching the size to the varying flows required by different actuator paths. Its modular design includes a control cover that houses control bores and may include additional features such as stroke limitation, hydraulically controlled directional seat valves, or shuttle valves depending on the overall function desired. Electrically operated directional spool or seat valves can also be incorporated into the control cover for enhanced functionality. This model operates based on pressure differential across three key areas: A1, A2, and A3. The area at valve seat A1 serves as a reference point while annulus area A2 is designed to be either 0.7 times or 0.3 times of area A1 based on specific grading to achieve different area ratios (A2:A1) of either 0.7:1 or 0.3:1 respectively. Area A3 equates to the sum of areas A1 and A2. The LC25B00E7X/V's operation is influenced by these areas; areas A1 and A2 contribute to opening forces while area A3 alongside a closing spring influences closing forces. The resultant force direction determines the spool position within the valve. This Bosch Rexroth model facilitates flow from port A to B or vice versa with zero leakage when blocking channel B using pilot oil discharge from channel B or an external pilot oil supply. It accommodates various sealing materials like FKM and supports multiple hydraulic fluids including HL, HLP, HLPD, HVLP, HVLPD, HETG, HEES, HEPG, HFDU, and HFDR. With its diverse capabilities and customizable options such as valve poppet with or without damping nose and differing cracking pressures based on area ratios provided in different configurations—alongside maximum operating pressures up to bar and maximum flow rates up to l/min—the LC25B00E7X/V offers robust performance for complex hydraulic systems requiring precise fluid control.
