Pressure Relief Valve DBW20B2-5X/150-6EG24N9K4E - Bosch Rexroth R901541162

A setting range of 4 to 150 bar covers power units that work well below the 350 bar limit of the valve itself. Adjustment happens on the internal hexagon under the protective cap, so the value stays put in rough service. The pilot-operated poppet valve sits on a subplate to ISO 6264-08-13 and discharges up to 400 l/min.

Benefits

• Setting range 4 to 150 bar, maximum operating pressure 350 bar
• Flow up to 400 l/min across the subplate interface to ISO 6264-08-13
• Poppet seat design keeps leakage limited in the closed position
• Internal hexagon with protective cap, so the pressure stage is covered against accidental turning
• Solenoid actuation at 24 VDC in two switching positions, 3-pole connector (2 + PE) to EN 175301-803
• 5.3 kg mass, NBR seals for HL hydraulic fluid

Application

The usual place for this valve is the pump outlet of a power unit feeding cylinders at 150 bar or less. Solenoid actuation switches the circuit from the control cabinet without touching the pressure setting. Size 25 matches pumps delivering up to 400 l/min.
