Pressure Relief Valve DBW20B2-5X/200Y6EG24N9K4E - Bosch Rexroth R900786923

The DBW20B2-5X/200Y6EG24N9K4E sets pressure from 4 to 200 bar, which lines up with circuits designed for 200 bar. It passes up to 450 l/min, works as a pilot-operated poppet valve on a subplate and weighs 5.38 kg. Unloading runs on a 24 VDC solenoid.

Benefits

• Setting range 4 to 200 bar, matching the design pressure of many standard power units
• 450 l/min flow, maximum operating pressure 350 bar, size 25
• Poppet valve with 2 ports on an ISO 6264-08-13 connection pattern
• 24 VDC solenoid unloading through a 3-pole connector (2 + PE)
• Internal hexagon under a protective cap, NBR seals, 5.38 kg

Application

It is fitted to 200 bar power units in machine tools, presses and clamping rigs. Solenoid unloading lets the pump keep turning between strokes without building pressure, which saves drive power and limits oil heating. On a subplate the change against an identically coded unit is bolt work only.
