Pressure Relief Valve DBW30B2N5X/280YS6EG24N9K4R12E - Bosch Rexroth R901016133

The plant is designed around 280 bar, so the valve has to limit exactly there and take the full pump flow at full lift. The DBW30B2N5X manages 700 l/min with an adjustment range of 4 to 280 bar.

Benefits

• Adjustment range of 4 to 280 bar for circuits designed below the 350 bar operating pressure.
• 700 l/min of relief capacity in size 32.
• 7.05 kg with subplate mounting to ISO 6264-10-17.
• Pilot-operated poppet valve with spool symbol B and two switching positions.
• Setting through an internal hexagon with protective cap.
• 24 V DC solenoid, 3-pole connector (2 + PE) to EN 175301-803, NBR seals.

Technical data

Applications

The range up to 280 bar covers many presses, injection moulding machines and lifting gear whose cylinders are rated for that figure. At 700 l/min the valve stays inside its rating even with several pumps running in parallel. The NBR seals match HL hydraulic fluid.
