Pressure Relief Valve DBW30A2-5X/315S6EW110N9K4R12 - Bosch Rexroth R901583732

A main circuit with high flow needs a pressure relief valve that does not become a restriction when it opens. The pilot-operated DBW30A2-5X/315S6EW110N9K4R12 discharges up to 650 l/min and is adjustable in the 4 to 315 bar range.

Benefits

• Setting range 4 to 315 bar through an internal hexagon with a protective cap.
• 650 l/min flow at 350 bar maximum operating pressure.
• Pilot-operated poppet design with two ports and two switching positions.
• Solenoid actuation at 110 to 120 VAC, 3-pole connector (2 + PE) to EN 175301-803.
• Connection pattern ISO 6264-10-17, NBR seals, HL fluid, 6.5 kg weight.

Technical data

Applications

The valve is used as system pressure limitation in presses, power units and test rigs with a high oil flow. The protective cap over the internal hexagon secures the set pressure against unintended adjustment. The electrical connection is laid out for alternating voltage of 110 to 120 V and is therefore not compatible with 24 V circuits.
