Pressure Relief Valve DBW20BG2-5X/230-6EG24N9K4E - Bosch Rexroth R901531615

When the pump has to idle without pressure, a built-on directional spool valve handles solenoid unloading while the poppet seat pressure stage keeps limiting the circuit. The setting range starts at 3.8 bar and reaches 230 bar. Threaded connection makes a separate subplate unnecessary, and the valve weighs 6.9 kg.

Benefits

• Solenoid unloading through a built-on directional spool valve lets the pump idle without pressure
• Setting range 3.8 to 230 bar, maximum operating pressure 350 bar
• Threaded connection instead of subplate mounting, no separate subplate required
• Pressure stage in poppet seat design with internal hexagon and protective cap
• Flow up to 400 l/min in size 25 at 6.9 kg mass
• 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL fluid

Application

This variant earns its place wherever the pump should not deliver against the set pressure between two working strokes. Unloading cuts the power lost during idle periods and keeps oil temperature down. Piping runs straight to the valve, which saves time when retrofitting an existing power unit.

Manufacturer

Bosch Rexroth lists this pressure relief valve DBW20BG2-5X/230-6EG24N9K4E under material number R901531615. Data sheets RE 25802 and RE 25802-B carry the characteristic curves, the installation dimensions and the subplate data.
