Pressure Relief Valve DBW52BP2-3X/100XYU6EG24NK4 - Bosch Rexroth R900777080

Cooling and flushing circuits usually run below 100 bar yet call for large oil volumes. The DBW52BP2-3X/100XYU6EG24NK4 is graded for exactly that: adjustment range 4 to 100 bar at flows up to 2000 l/min.

Benefits

• Adjustment range 4 to 100 bar, giving finer resolution of the setting than a spring rated for 315 bar.
• Relief capacity up to 2000 l/min in size 52, suited to large circulating volumes.
• Pilot-operated seat valve, spool symbol B, low-leakage sealing when closed.
• Electrical unloading at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803.
• Internal hexagon with protective cap, weight 28.06 kg, NBR seals.

Applications

The valve serves flushing, cooling and circulation circuits of large power units as well as prefill circuits of presses. Operating pressure of the size reaches 315 bar, while the control spring caps the setting at 100 bar and so protects downstream coolers and filters.
