Pressure Relief Valve DBW20B2-5X/330YS6EG24N9K4R12E - Bosch Rexroth R901494690

The DBW20B2-5X/330YS6EG24N9K4R12E is rated for 450 l/min discharge flow and adjusts from 4 to 330 bar. It therefore protects circuits working just below the 350 bar operating limit.

Benefits

• Discharge flow up to 450 l/min instead of the common 400 l/min
• Adjustment range 4 to 330 bar at 350 bar permitted operating pressure
• Pilot-operated seat valve with internal hexagon and protective cap
• Spool symbol B, two switching positions, 24 VDC solenoid actuation
• Subplate mounting ISO 6264-08-13, size 25, two ports
• 6.2 kg weight, NBR seals, CE conformity

Application

Large power units in presses and forming machines reach 450 l/min quickly during a relief event. An undersized relief valve would allow an impermissible pressure rise there. The range to 330 bar covers high pressure circuits with margin to the system limit.
