Oil constantly discharged across a pressure limit turns into heat. The pump safety block DBAW15BF2-2X/200 switches the pump to unpressurised circulation during pauses, otherwise limits to between 6 and 200 bar and carries up to 300 l/min in size 16.

Total price
Oil discharged across a relief valve for hours turns into heat that has to be cooled away. The pump safety block DBAW15BF2-2X/200ZZ6EG24N9K4A08 instead switches the pump to unpressurised circulation whenever the circuit is idle, and otherwise limits pressure to between 6 and 200 bar.
Benefits
- Unpressurised circulation during pauses through the built-on directional spool valve at 24 VDC.
- Pressure adjustment range 6 to 200 bar, secured by an internal hexagon with a protective cap.
- Flange connection, port pattern of the directional valve ISO 4401-03-02-0-05.
- Up to 300 l/min in size 16, two ports in two switching positions.
- Pilot-operated pressure valve in poppet seat design, maximum operating pressure 350 bar.
- 7.9 kg, NBR seals for HL hydraulic fluid.

Applications
Machines with long holding and waiting phases benefit most from a pump that does not deliver against pressure during those periods. The drive draws less power and the cooling demand falls without fitting an additional circulation valve. Pressure limitation in poppet seat design stays effective throughout.
