Inrush current is smaller when the pump may start unpressurised. The pump safety block DBAW15BH2-2X unloads electrically through a built-on directional valve for that purpose and then limits pressure to between 6 and 315 bar at up to 300 l/min.

Starting a cold power unit against full pressure draws a high inrush current. The pump safety block DBAW15BH2-2X/315ZZ6EG24N9K4A08 first switches delivery to unpressurised circulation through its built-on directional spool valve and then limits pressure to a value between 6 and 315 bar.
Benefits
- Unpressurised start through solenoid unloading, the built-on directional valve is switched at 24 VDC.
- Pressure adjustment range 6 to 315 bar behind an internal hexagon with a protective cap.
- High-pressure flange connection, port pattern of the directional valve ISO 4401-03-02-0-05.
- 300 l/min in size 16, two ports in two switching positions.
- Maximum operating pressure 350 bar, pilot-operated pressure valve in poppet seat design.
- 7.86 kg, NBR seals for HL hydraulic fluid.

Applications
Unpressurised circulation at start relieves motor and coupling and helps particularly with cold, viscous oil. During operation the same block handles pressure limitation so that pump and lines never exceed the set value. During pauses the system stays unloaded, which keeps the oil temperature down.
