Pumpensicherheitsblock DBAWR30BH2N1X/315-6EG24N9K4VE - Bosch Rexroth R901384620

Protecting a pump and starting it without pressure usually takes two valves and the piping between them. This pump safety block does both in one housing, takes up to 520 l/min and limits pressure to 3.7 up to 315 bar.

Benefits

• Pressure limitation and electrical unloading through a built-on directional spool valve in one block, which removes the separate piping
• Flow of up to 520 l/min in size 32
• Pressure adjustment range of 3.7 to 315 bar through an internal hexagon with protective cap
• High-pressure flange as the connection type, so the block mounts directly on the pump
• Pressure valve in poppet seat design with 2 switching positions on 2 ports
• Solenoid actuation at 24 VDC, FKM seals, CE conformity, mass of 10.34 kg

Applications

The block sits on the pressure port of power unit pumps in presses, test rigs and forging plants. Starting without pressure relieves the drive motor and lowers the breakaway torque. The high-pressure flange calls for a matching counterpart on the pump.
