Description
This pilot-operated size 25 pressure relief valve works with spool pattern B and weighs 6.9 kg. It limits system pressure at flow up to 500 l/min and vents the circuit during idle periods through its mounted directional valve.
Benefits
- Spool symbol B, two switching positions on two ports.
- Flow up to 500 l/min, maximum operating pressure 350 bar.
- Build DBW20B2-5X/315YUS in size 25.
- Subplate mounting to ISO 6264-08-13, supply voltage 24 VDC.
- NBR seals, HL hydraulic fluid.
- Connector, 3-pole (2 + PE) to EN 175301-803, weight 6.9 kg.
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.
