Pressure Relief Valve DBW30BG2-5X/315Y6EG24N9K4/12 - Bosch Rexroth R900921899

Not every power unit has a matching subplate, sometimes the pump circuit simply ends in pipework. The pilot-operated pressure relief valve DBW30BG2-5X/315Y6EG24N9K4/12 in size 32 is therefore tied in by threaded connection and works with three ports.

Benefits

• Threaded connection with three ports, no subplate needed in the power unit.
• Adjustment range 3.8 to 315 bar through an internal hexagon with protective cap.
• Solenoid unloading via a built-on directional spool valve, two switching positions to symbol B at 24 VDC.
• Pressure valve in poppet seat design, closing tightly while limiting.
• 650 l/min at a maximum operating pressure of 350 bar, weight 6.5 kg.

Applications

On retrofitted power units and in small series the effort of a manifold rarely pays off, so the valve goes straight into the pipe run. The built-on directional spool valve handles the unloading, letting the pump idle without pressure during pauses with no extra valve to pipe up. The adjustment range starts at 3.8 bar and so covers pre-load and circulation pressures as well.
