Pressure Relief Valve DBW30B1-5X/315XY6EG24N9K4/12 - Bosch Rexroth R978918908

In a densely piped power unit the pressure adjustment on a large valve is hard to reach. This pilot-operated seat valve in size 32 is set on a rotary knob across 4 to 315 bar and passes up to 650 l/min.

Benefits

• Rotary knob for pressure adjustment, so resetting needs no tool
• Adjustment range of 4 to 315 bar at a maximum operating pressure of 350 bar
• 650 l/min relief capacity through the ISO 6264-10-17 interface in size 32
• Spool symbol B with two switching positions and two ports
• Electrical unloading through the mounted solenoid at 24 VDC
• 6.3 kg on subplate mounting, NBR seals for HL hydraulic fluid

Applications

The valve is used on large hydraulic power units, presses and test rigs delivering up to 650 l/min. The rotary knob shortens setting during commissioning and changeover. During breaks the solenoid takes the pump circuit pressureless.
