Pressure Relief Valve DBW20B2-5X/330Y6EG24N9K4E - Bosch Rexroth R901000222

With a setting range of 4 to 330 bar the DBW20B2-5X/330Y6EG24N9K4E sits at the upper end of the series and still passes 450 l/min. The pilot-operated poppet valve mounts on an ISO 6264-08-13 subplate and is unloaded on 24 VDC. Maximum operating pressure is 350 bar.

Benefits

• Setting range 4 to 330 bar for circuits close to the permitted system pressure
• 450 l/min flow in size 25 at a maximum operating pressure of 350 bar
• Subplate mounting to ISO 6264-08-13, interchangeable against identically coded predecessors
• Internal hexagon under a protective cap, secured against accidental adjustment
• Poppet seat design, NBR seals, 5.34 kg

Application

The valve is used where presses, forging plant and clamping systems call up high pressure for short periods. A poppet seat keeps the closed circuit tight, which cuts make-up flow on holding duties. On an existing size 25 subplate the swap needs no pipework.
