Pressure Relief Valve DBW20B2-5X/160YS6EG24N9K4R12E - Bosch Rexroth R901122089

The DBW20B2-5X/160YS6EG24N9K4R12E combines an adjustment range of 4 to 160 bar with 450 l/min discharge flow. That pairing is wanted when a powerful pump feeds pressure sensitive consumers.

Benefits

• Adjustment range 4 to 160 bar at 450 l/min discharge flow
• Operating pressure permitted to 350 bar at the port
• Pilot-operated seat valve with internal hexagon and protective cap
• Spool symbol B, two switching positions, 24 VDC
• Size 25, two ports, ISO 6264-08-13
• 5.86 kg weight, NBR seals, CE conformity

Application

Systems with large cylinder areas already produce considerable force at moderate pressure. A 160 bar ceiling protects components rated for lower pressures. The cross section for 450 l/min prevents an impermissible pressure rise when the valve responds.

Manufacturer
