Pressure Relief Valve DBW52BP2-3X/315XU6EG24NK4 - Bosch Rexroth R901010363

A relief valve of this size decides the safety of a whole power unit. The DBW52BP2-3X/315XU6EG24NK4 holds system pressure at 4 to 315 bar, passes up to 2000 l/min and weighs 26 kg.

Benefits

• Relief capacity up to 2000 l/min, so several pumps can share one protection point.
• Adjustment range 4 to 315 bar at the internal hexagon, protective cap against accidental change.
• Solenoid unloading at 24 VDC puts the power unit into idle, 3-pole connector (2 + PE) to EN 175301-803.
• Pilot-operated seat valve with spool symbol B, two switching positions, two ports.
• Weight 26 kg, subplate mounting, NBR seals for hydraulic fluid class HL.

Applications

A common place is the tank lid of large power units in press lines and foundries. During start-up the solenoid stays energised, the unit runs up unloaded and only then goes to working pressure. That spares pump and coupling.
