Pressure Relief Valve DBW10B2-5X/220-6EG24N9K4E - Bosch Rexroth R901416981

In pilot-operated relief valves the cracking pressure stays largely constant across the flow range. The DBW10B2-5X/220-6EG24N9K4E uses that design across 4 to 220 bar and discharges up to 200 l/min in size 10.

Benefits

• Adjustment range 4 to 220 bar at a maximum operating pressure of 350 bar.
• Pilot-operated seat valve, the characteristic stays flat across the flow range.
• Up to 200 l/min in size 10, symbol B, two ports.
• Internal hexagon with protective cap as the adjustment.
• 24 VDC solenoid actuation, 3-pole connector (2 + PE) to EN 175301-803.
• 5 kg weight, subplate mounting to ISO 6264-06-09, NBR seals.

Applications

The valve protects injection moulding, pressing and clamping circuits whose working pressure sits around 200 bar. The flat characteristic keeps pressure within narrow limits even when flow varies during the cycle. The protective cap prevents the accepted setting from being disturbed.
