Pressure Relief Valve DBW 30 B2-5X/315-6EG12N9K4/12=CSA - Bosch Rexroth R978013987

Where a machine offers only a 12 V control supply, the pressure protection has to live within it. The DBW 30 B2-5X uses a 12 VDC solenoid, caps pressure across 4 to 315 bar and follows symbol B in two switching positions.

Benefits

• 12 VDC solenoid, wired through a connector, 3-pole (2 + PE) according to EN 175301-803.
• Setting range 4 to 315 bar at an internal hexagon under a protective cap.
• 650 l/min rated flow at up to 350 bar operating pressure.
• Poppet valve with pilot stage, unloading to symbol B in two switching positions.
• 6.5 kg on subplate pattern ISO 6264-10-17, NBR seals for HL hydraulic fluid.

Technical data

Application

Valves on a 12 V solenoid serve mobile power units as well as plants whose control voltage comes from a battery. Hydraulically size 32 behaves exactly as the 24 V version does, so pattern and mounting dimensions stay identical. Check before installation that the supply line carries the inrush current of the solenoid.
