Pressure Relief Valve DBW 30 AG2-5X/315YU6EG12N9K4/12 - Bosch Rexroth R978913370

When the return line fluctuates strongly, the pilot oil should take its own path. The pilot-operated pressure relief valve DBW 30 AG2-5X/315YU6EG12N9K4/12 has a third port for that, is driven at 12 VDC and works between 2 and 315 bar.

Benefits

• Three ports, the pilot oil is routed separately.
• Supply voltage 12 VDC for machines with a 12 V control level.
• Setting range 2 to 315 bar, symbol A, maximum operating pressure 350 bar.
• Threaded connection in size 32, unloading through a built-on directional spool valve.
• Up to 650 l/min, NBR seals, 6.3 kg, HL hydraulic fluid.

Technical data

Application

In machines with several consumers the pressure in the return line swings with every movement. A separate pilot oil path decouples the pilot stage from that and keeps the setting stable. The 12 V version suits controls that work without a 24 V level.
