Rexroth LFA 16 D-71/FX10
The Bosch Rexroth LFA 16 D-71/FX10 is a logic cover element designed as a pilot-operated check valve for hydraulic systems. This NG16 size component is intended for manifold or block installation, providing reliable one-way flow control. The valve can be hydraulically piloted to allow reverse flow. A key feature, denoted by “F” in the model code, is its pre-opening capability, which ensures smooth decompression and helps prevent hydraulic shock in the system. The “X10” designation indicates a check valve cracking pressure of 1 bar. This robust component is part of Rexroth’s extensive range of hydraulic valves, known for their durability and performance in demanding industrial applications.
