Pumpensicherheitsblock DBAW15BH2-2X/200Z6EG24N9K4 - Bosch Rexroth R901277303
A power unit running at 200 bar needs pressure protection and unloading in a single component. This pump safety block limits pressure across a 6 to 200 bar range and unloads the pump through the built-on directional valve. It handles 300 l/min and weighs 7.64 kg.

Description
On start-up the pump should run up unloaded, while in service the circuit has to be protected against overload. This pilot operated safety block in size 16 does both and is set up for an adjustment range of 6 to 200 bar.
Benefits
- Pressure adjustment range 6 to 200 bar, internal hexagon with protective cap
- Solenoid unloading through a built-on directional spool valve at 24 V DC
- Flow up to 300 l/min, maximum operating pressure 350 bar
- High-pressure flange connection, size 16
- Pressure valve in poppet seat design, two ports, weight 7.64 kg
Application
The block sits directly at the pump outlet of a power unit and covers both protection and unloading. During start the pump stays unloaded through the directional valve, and only then does the circuit build up to the setting. The internal hexagon with its protective cap prevents accidental adjustment.
