FAQ

A logic cover is mounted on a cartridge valve (logic element) seated in a manifold block. This LFA 50 WEA-71/ includes a pilot valve that controls the main cartridge valve, allowing for complex hydraulic circuits to be built for controlling pressure, flow, and direction.

"LFA" is the Rexroth type code for a logic cover. "50" refers to the nominal size (NG50), indicating the size of the cartridge valve it fits. "WEA" specifies the type of built-in pilot valve: "WE" is a directional spool valve, and "A" denotes solenoid actuation.

This valve cover is designed for use with mineral oil-based hydraulic fluids (HL, HLP) according to DIN 51524. For use with other fluids, it is essential to consult the official Bosch Rexroth datasheet to ensure compatibility with the seals.
