Pressure Relief Valve DBW20B2-5X/170Y6EG24N9K4E - Bosch Rexroth R901013627

A working pressure of 170 bar appears where piston area and force already match well and pressure need not rise further. This version covers 4 to 170 bar while taking up to 450 l/min. Adjustment is made on the internal hexagon under the protective cap, and the mass is 5.3 kg.

Benefits

• Setting range 4 to 170 bar at a flow rating of 450 l/min
• Pilot-operated poppet valve in size 25 with spool symbol B
• Maximum operating pressure 350 bar, well clear of the setting stage
• 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
• 5.3 kg mass, NBR seals for HL hydraulic fluid

Application

The version suits power units on lifting gear, clamping bridges and feed units that move a lot of oil at medium pressure. The flow headroom keeps pressure close to the set point when the valve responds. Solenoid actuation switches the circuit without changing the pressure stage.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20B2-5X/170Y6EG24N9K4E under material number R901013627. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data. Size the return line for 450 l/min so that back pressure does not raise the value that was set.
