The Bosch Rexroth LFA25G-7X/V (R901085238) is a sophisticated way cartridge valve designed for integration into a compact block system. This valve is engineered to facilitate pressure, directional, and throttle functions, or any combination thereof within hydraulic systems. It achieves this versatility through the use of pilot control valves that dictate the operational mode of the power section. The LFA25G-7X/V valve's construction includes a control cover that houses control bores and may include additional features such as stroke limitation, a hydraulically controlled directional seat valve, or a shuttle valve as necessary for the desired function. Furthermore, it can accommodate electrically operated directional spool or seat valves on the control cover if required. This model employs an installation kit comprising several components: a bushing, ring (applicable up to NG), valve poppet (with options for damping nose configurations), and a closing spring. The functionality of this way cartridge valve is pressure-dependent; it utilizes three distinct pressurized areas (A1, A2, A3) to achieve its operation. The area ratios between these zones—either 0.7:1 or 0.5:1—along with different springs and cracking pressures available, allow for tailored performance in various hydraulic applications. The design ensures that areas A1 and A2 are active in the opening direction while area A3 along with the spring influence the closing direction. The balance between these forces dictates the spool position within the valve. Additionally, this model permits fluid flow from port A to B or vice versa while ensuring that when area A3 is pressurized by pilot oil from channel B or an external supply, channel A remains securely blocked without leakage. Overall, the Bosch Rexroth LFA25G-7X/V way cartridge valve offers customizable solutions for complex hydraulic systems where space efficiency and multi-functional capabilities are paramount.
