Pressure Relief Valve DBW30B2-5X/200S6EG24N9K4R12/12 - Bosch Rexroth R978916224

If the pressure stage is chosen too high, the adjusting screw ends up at the bottom of its travel. This version covers 4 to 200 bar and passes up to 650 l/min through the pilot-operated seat valve in size 32.

Benefits

• Pressure stage 4 to 200 bar matched to medium working pressure, maximum operating pressure 350 bar.
• Flow up to 650 l/min, subplate mounting to ISO 6264-10-17.
• Electrical unloading at 24 VDC, 2 switching positions, spool symbol B.
• 6.3 kg weight in size 32 with 2 ports.
• NBR seals for HL hydraulic fluid.
• 3-pole connector (2 + PE) to EN 175301-803, pressure set through an internal hexagon with protective cap.

Application

The valve is used in power units of presses, clamping fixtures and test rigs whose system pressure sits between 100 and 180 bar. Inside that window the pressure can be met more finely across the adjustment travel. Between the 200 bar stage and the 350 bar maximum operating pressure there is headroom.
