Pressure Relief Valve DBW20B2-5X/315Y6EG24N9K4E - Bosch Rexroth R901016416

When a large pump discharges across the valve at 315 bar, the wasted power becomes considerable and pressure must not climb above the set point. This version is therefore rated for 450 l/min and covers a setting range of 4 to 315 bar. The subplate interface follows ISO 6264-08-13, and adjustment is made on the internal hexagon under the protective cap.

Benefits

• Setting range 4 to 315 bar for the 315 bar nominal pressure class
• 450 l/min flow rating, matched to large pumps
• Pilot-operated poppet valve in size 25 with spool symbol B
• Internal hexagon with protective cap, subplate mounting to ISO 6264-08-13
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
• 5.38 kg mass, NBR seals for HL hydraulic fluid

Application

The field of use covers presses, test rigs and drives of heavy machinery working at 315 bar with high delivery. Because the valve takes the full flow, the pressure rise on response stays small. The solenoid switches the circuit without changing the stage that was set.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/315Y6EG24N9K4E under material number R901016416. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. At 315 bar and 450 l/min, consider the cooling capacity of the power unit as well, since discharging generates a lot of heat.
