Shutting off a flow of 300 l/min creates pressure peaks that load the pump. The DBAW30BH2-2X/230ZZ6EG24N9K4A00E catches them, holds pressure across 6 to 230 bar and unloads by solenoid at 24 VDC.

Total price
When a flow of 300 l/min is blocked suddenly, pressure ahead of the pump rises fast. The DBAW30BH2-2X/230ZZ6EG24N9K4A00E pump safety block in size 32 limits it to the value set between 6 and 230 bar and also opens a path to tank.
Benefits
- Pressure adjustment range 6 to 230 bar, maximum operating pressure 350 bar.
- Pilot-operated poppet seat valve holding the set pressure across the full 300 l/min flow.
- Solenoid unloading at 24 VDC through a built-on directional spool valve with symbol B.
- High-pressure flange, two ports, HL hydraulic fluid, NBR seals.
- Connector 3-pole (2 + PE) according to EN 175301-803 with protective earth.
- 8.5 kg mass, CE conformity.

Applications
The block belongs on power units feeding large cylinders at high flow. When the cylinder reaches its end stop the valve carries off the surplus without stalling the drive. Solenoid unloading lets the unit be switched pressureless from the control cabinet.
