Pressure Relief Valve DBW 30 AG2-5X/200YU6EG24N9K4/12 - Bosch Rexroth R978030917

A pressure relief valve works most precisely when the operating point sits in the middle of its setting range. The pilot-operated DBW 30 AG2-5X/200YU6EG24N9K4/12 covers 2 to 200 bar and therefore suits circuits around 150 bar, at up to 650 l/min relief flow.

Benefits

• Setting range 2 to 200 bar for the medium working pressure band.
• Symbol A with two ports, unloading through a built-on directional spool valve.
• Threaded connection, no manifold needed, size 32.
• Internal hexagon with protective cap, maximum operating pressure 350 bar.
• Pressure valve in poppet seat design, NBR seals, 6.3 kg, HL hydraulic fluid.

Application

Feed drives, clamping systems and power units on machine tools often sit between 100 and 200 bar. The valve limits there with a well resolved setting and takes the pressure away through the solenoid when the cycle pauses. The seat design holds the setting even after long standstill periods.
