Pressure Relief Valve DBW20B2-5X/215Y6EG24N9K4E - Bosch Rexroth R901371424

When a large pump discharges across the relief valve, the permissible flow decides how far pressure climbs above the set point. This version is rated for 450 l/min and covers a setting range of 4 to 215 bar. Adjustment is made on the internal hexagon under the protective cap, and the mass is 5.38 kg.

Benefits

• 450 l/min flow rating keeps pressure close to the set point while discharging
• Setting range 4 to 215 bar at a maximum operating pressure of 350 bar
• Pilot-operated poppet valve in size 25 with spool symbol B
• 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
• 5.38 kg mass, NBR seals for HL hydraulic fluid

Application

The field of use covers power units with a powerful pump whose cylinders work at around 200 bar, for instance in lifting and tilting equipment. Because the valve can take the full delivery, oil heating during discharge stays predictable. Solenoid actuation switches the circuit independently of the pressure setting.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/215Y6EG24N9K4E under material number R901371424. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Size the return line so that it takes 450 l/min without noticeable back pressure.
