Pressure Relief Valve DBW20B2-5X/315-6EG24N9K4E - Bosch Rexroth R901210215

Pumps of the 315 bar class need a relief valve adjustable exactly up to that figure while keeping reserve in the body above it. This version covers 4 to 315 bar, with the maximum operating pressure standing at 350 bar. A flow of 400 l/min discharges across the ISO 6264-08-13 subplate interface.

Benefits

• Setting range 4 to 315 bar with body reserve up to 350 bar
• Spool symbol B, two switching positions, two ports
• Pilot-operated poppet valve in size 25 rated for up to 400 l/min
• Subplate mounting to ISO 6264-08-13, internal hexagon with protective cap
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.42 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

The field of use covers drives and presses running on pumps of the 315 bar nominal class. Because the setting range ends exactly there, the cut-off pressure cannot accidentally be turned beyond the rating of the pump. The solenoid switches the circuit from the control system.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/315-6EG24N9K4E under material number R901210215. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Keep a sufficient gap between cut-off pressure and working pressure so the valve stays closed in normal operation.
