Pressure Relief Valve DBW10B2-5X/200S6EG24N9K4R12/12 - Bosch Rexroth R978018728

For power units of medium output size 10 is sufficient as long as the flow stays below 250 l/min. This valve limits pressure across 4 to 200 bar, works pilot-operated in a seat design and is set through an internal hexagon with a protective cap.

Benefits

• 250 l/min relief capacity in size 10, matched to compact power units
• Adjustment range of 4 to 200 bar at a maximum operating pressure of 350 bar
• ISO 6264-06-09 interface for mounting on a standard subplate
• Pilot-operated seat valve closing tightly at rest
• Electrical unloading through the solenoid at 24 VDC, spool symbol B
• Internal hexagon with protective cap, NBR seals, weight 4.3 kg

Applications

It is used in hydraulic power units of machine tools, clamping devices and test equipment running around 200 bar. The low mass of 4.3 kg makes assembly in the manifold easier. During start-up the electrical unloading takes load off the drive.
