Specifications

Supplier part number:	Rexroth - BOSCH - LFA_25_GWA-7X
Name:	Logic Elements (Rexroth - BOSCH). - Directional Control Function , Control Cover. - Type : LFA. - Nominal Size NS 25. - GWA : For Mounting Directional Valve .
Description:	The LFA25GWA-7X control cover is designed for directional control functions, with the "GWA" code signifying it is prepared for mounting a directional pilot valve. It achieves the directional control function by providing an interface for a separate pilot valve . 🔧 Function and Design The LFA..GWA cover itself is part of the LC/LFA cartridge valve system and serves as the platform that dictates the main valve's behavior . Its key features include: Mounting Interface for Pilot Valve: It is specifically prepared for the setup of a directional pilot control valve. The cover's design allows a standard directional spool valve, such as a 4WE 6 D…, or a directional seat valve like the M-3SEW 6…, to be mounted directly onto it . Integral Shuttle Valve: The "G" in the code indicates the presence of an integrated shuttle valve within the control cover . This internal component is often used to supply pilot oil from the higher of two pressure sources, ensuring reliable pilot control. Pilot Operation: The mounted pilot valve directs pilot oil flow to actuate the main cartridge element. By selecting a specific type of pilot valve, the logic element can be configured to fulfill various directional control functions for high-flow applications. 📋 Key Technical Specifications (NS 25) The following specifications are relevant for the LFA25GWA variant, as seen in the technical data .
