Pressure Relief Valve DBW20BG2-5X/200US6EG24N9K4R12/12 - Bosch Rexroth R901143810

Pilot-operated size 25 pressure relief valve of poppet seat design with threaded connection, rated for 500 l/min. The adjustment range runs from 2 to 200 bar, and a built-on directional spool valve unloads the circuit electrically.

Advantages

• Flow of 500 l/min at a maximum operating pressure of 350 bar
• Pressure adjustment range of 2 to 200 bar via internal hexagon with protective cap
• Solenoid unloading through the built-on directional spool valve at 24 VDC, 2 switching positions to spool symbol B
• Poppet seat design with 2 ports to ISO 6264-08-13
• Threaded connection and a weight of 5.59 kg, NBR seals for HL hydraulic fluid

Application

The valve limits pressure in power units and control blocks where pump flows reach 500 l/min. Electrical unloading lets the installation idle at zero pressure during breaks, which reduces heating of the HL hydraulic fluid. The threaded connection allows direct installation in the line without a separate subplate.
