Pressure Relief Valve DBW30B1N5X/120Y6EG24N9K4E - Bosch Rexroth R901245047

Fast approach strokes and large bore cylinders call for a lot of oil at little pressure. This pilot-operated pressure relief valve discharges up to 700 l/min and limits pressure through a rotary knob across a range of 4 to 120 bar.

Benefits

• 700 l/min maximum flow, matched to rapid traverse and filling circuits with high oil demand.
• Setting range of 4 to 120 bar, so the scale sits entirely inside the pressure band actually used.
• Rotary knob for readjustment at the machine without tools.
• Maximum operating pressure of 350 bar, so the body is rated well above the setting range.
• Seat valve closing tightly in the rest position.
• 6.46 kg weight with solenoid actuation at 24 VDC.

Technical data

Application

A fit for rapid traverse circuits in large presses, filling circuits and power units with high circulating volume. The low setting range protects consumers that cannot take high pressure. The solenoid switches the system to zero pressure during waiting times, which reduces heat input into the HL hydraulic fluid.
