Pumpensicherheitsblock DBAW30BH2-2X/230Z6EG24N9K4A00E - Bosch Rexroth R901410230

Building relief and unloading as two separate parts means two sets of piping and two possible leak points. This block combines them, holds pressure within 6 to 230 bar and passes 300 l/min through the high-pressure flange.

Benefits

• Pressure stage 6 to 230 bar on a pilot-operated valve of poppet seat design, maximum operating pressure 350 bar.
• Flow up to 300 l/min in size 32 with 2 ports.
• Unloading through a built-on directional spool valve at 24 VDC with 2 switching positions.
• 8.16 kg weight connected by high-pressure flange, spool symbol B.
• NBR seals for HL hydraulic fluid, 3-pole connector (2 + PE) to EN 175301-803.
• CE conformity, pressure set through an internal hexagon with protective cap.

Application

The block belongs at the pump outlet of power units in presses, test rigs and clamping systems. During start-up the drive motor stays unloaded because the built-on directional spool valve opens the circuit to tank. Once the motor is up to speed the 230 bar stage takes over protection.
