Pressure Relief Valve DBW30A2N5X/50US6EG24N9K4R12 - Bosch Rexroth R900977466

A low pressure branch protected by a 315 bar valve can hardly be set accurately. The pilot-operated DBW30A2N5X/50US6EG24N9K4R12 works from 2 to 50 bar instead and still accepts the full 650 l/min of size 32.

Benefits

• Adjustment range 2 to 50 bar, the entire scale lies inside the working range of a low pressure branch.
• 650 l/min with symbol A, flow capacity is not cut back by the low setting.
• 350 bar permitted operating pressure, the body carries system pressure even with the valve closed.
• Internal hexagon with protective cap, the setting stays secured after commissioning.
• 6.49 kg, subplate mounting ISO 6264-10-17, 24 VDC solenoid.

Applications

It is typically fitted in flushing and pre-fill circuits of large presses and in cooling oil loops. Because the spring is rated for 50 bar, the valve already responds to small pressure changes in the branch. HL hydraulic fluid and NBR seals match ordinary mineral oil duty.
