Load-Sensing Retrofit for Bosch SB23 LS (EHS) System

This newly developed end plate is a system designed to provide an additional interface for external control blocks on the valve block in a tractor with Bosch SB23 LS control units (for example, for front loader control units).

The system works independently of the type of pump installed.
Load-sensing control blocks can then be connected to this system.

The system replaces the end plate in the setup. The plate thickness in the area of the mounting bolts is matched to the original plate, so replacing the studs is usually not necessary. The mounting threads in the block are also included in the same way in this reproduction.
This valve plate contains all the necessary valve technology.

Important:

The system is only compatible with the SB23 LS system with mechanical control units (except for the valve for the rear hydraulics, which was always electric). It is not compatible with the SB23 LS EHS system, as the pilot pressure control is built in there.

For tractors with electric control units (CANbus valves), we offer the version as an intermediate plate here.

The three spacer rings for the studs are included in the scope of delivery.
