- Externally discharge the pilot oil from the proportional pressure relief valve type DBET
- Observe the pressure ratings and connection dimensions!
- Adjustment type for pressure switch type HED8 in brackets!
- Mating connectors, separate order
- If used on variable displacement pumps with DFLR controllers, the nozzle at port X of the pump control must be removed!
Notice! Preferred types and standard units are contained in the EPS (standard price list).
