Pressure Relief Valve DBW 10 B2-5X/315-6EG24N9DK24LV/12 - Bosch Rexroth R978905607

Pilot-operated size 10 pressure relief valve of poppet seat design, adjustable from 4 to 315 bar and rated for a flow of 250 l/min. The circuit stays within the set pressure even during load peaks, and the solenoid unloads the pump when required.

Advantages

• Pressure adjustment range of 4 to 315 bar via internal hexagon with protective cap, maximum operating pressure 350 bar
• Poppet seat design with tight shut-off in the closed position, 2 ports to ISO 6264-06-09
• Electrical unloading through the 24 VDC solenoid, 2 switching positions to spool symbol B
• Flow of 250 l/min at a weight of 4.3 kg with subplate mounting
• FKM seals matched to HL hydraulic fluid

Application

The valve protects pumps and actuators in presses, machine tools and test rigs against excessive pressure. The solenoid switches the circuit to zero pressure during standstill, which lowers drive power and oil heating. Installation is by subplate mounting on a plate to ISO 6264-06-09. HL is the intended hydraulic fluid.
