Pressure Relief Valve DBW30B2-5X/200U6EG24N9K4/12 - Bosch Rexroth R978912601

Standard power units in machine building are frequently rated for 200 bar, and the pressure valve should work exactly there. The pilot-operated DBW30B2-5X/200U6EG24N9K4/12 covers 2 to 200 bar, sits on a size 32 subplate and relieves up to 650 l/min.

Benefits

• Setting range 2 to 200 bar for power units rated at 200 bar.
• Subplate mounting to ISO 6264-10-17, no fittings on the valve itself.
• Internal hexagon with protective cap, the setting stays put after commissioning.
• Solenoid actuation at 24 VDC, symbol B, two ports.
• Up to 650 l/min, NBR seals, 6.3 kg, HL hydraulic fluid.

Application

Power units for machine tools, presses and test rigs are often supplied as a kit rated at 200 bar. A valve with a matching setting range resolves finely inside that window. Subplate mounting keeps the lines away from the valve and allows a swap without opening the piping.
