Application

Valves with a non-standard spool pattern are usually bought as a spare for one particular machine, because the circuit diagram there is fixed. The standardised mounting pattern and the standard connector still keep the exchange straightforward, with no change to subplate or wiring.

Manufacturer

Bosch Rexroth lists this variant under material number R978903378. The circuit diagram of spool J73 and the associated limit values are documented in data sheet RE 23178, and the series overview in RE 07600-B.
