Pumpensicherheitsblock DBAW30AH2N1X/315S6SMG24N9K4B12VE - Bosch Rexroth R901483049
A pump needs protection against overpressure and a way to start up unloaded. This pump safety block in size 32 limits pressure within the set range of 3.7 to 315 bar and unloads the pump electrically through a built-on directional seat valve.

Description
On start-up a pump should not work against full system pressure, and in operation the pressure has to stay reliably limited. This pilot-operated pump safety block in size 32 covers both for flows up to 360 l/min.
Benefits
- Pressure limitation in poppet seat design with a setting range of 3.7 to 315 bar
- 350 bar maximum operating pressure and 360 l/min maximum volume flow in size 32
- Solenoid unloading through a built-on directional seat valve, switched on 24 V DC
- Pressure adjustment by internal hexagon with a protective cap against unintended change
- High-pressure flange connection, 9.8 kg weight, FKM seals, CE conformity
Application
The block sits straight at the pump outlet of power units in presses, test rigs and injection moulding machines. The poppet seat design keeps leakage low in the closed state. The solenoid lets the pump circulate unloaded for start and standstill.
