Pressure Relief Valve DBW20B2-5X/190S6EG24N9K4R12E - Bosch Rexroth R901541110

The DBW20B2-5X/190S6EG24N9K4R12E limits system pressure to a value between 4 and 190 bar. At a discharge flow of up to 400 l/min the pressure rise over the curve stays flat because the poppet seat design allows little leakage.

Benefits

• Adjustment range 4 to 190 bar, secured by internal hexagon and protective cap
• Discharge flow up to 400 l/min in size 25
• Pilot-operated seat valve, operating pressure permitted to 350 bar
• Subplate mounting to ISO 6264-08-13 with two ports
• 24 VDC solenoid actuation, two switching positions, spool symbol B
• 5.9 kg weight, NBR seals, CE conformity

Application

The 190 bar step suits power units at medium pressure level, for instance clamping hydraulics and conveying equipment. Subplate mounting to ISO 6264-08-13 allows fitting on existing control blocks. HL fluid and NBR seals form the usual pairing in a mineral oil circuit.

Manufacturer
