Technical data

Application

Unloading during idle periods lowers the power drawn by the drive and the heating of the oil, because the pump no longer delivers against the set pressure. On machines with long cycle pauses this shows directly in oil temperature and cooling demand.

Manufacturer

The Bosch Rexroth material number is R901559091. Characteristic curves, setting ranges and the dimensions of the connection pattern are documented in the pressure relief valve data sheet RE 25802 and in the supplement RE 25802-B.
