Pressure Relief Valve DBW20B2-5X/210-6EG24N9K4E - Bosch Rexroth R901522834

Power units running at 210 bar are the most common case in machine building, and the 4 to 210 bar setting range aims straight at them. The pilot-operated design keeps the pressure curve flat across the full 400 l/min, while the poppet seat closes tightly. Adjustment is made on the internal hexagon under the protective cap.

Benefits

• Setting range 4 to 210 bar for the usual medium pressure band
• Pilot-operated design gives a flat characteristic curve up to 400 l/min
• Spool symbol B with two switching positions and two ports
• Subplate mounting to ISO 6264-08-13 in size 25
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• 5.3 kg mass, NBR seals for HL hydraulic fluid

Technical data

Application

Target applications are hydraulic power units feeding cylinders and motors at 200 to 210 bar, for instance in clamping fixtures and feed drives. The wide setting range lets one valve serve several machines running at different working pressures. The solenoid switches the circuit without altering the pressure setting.
