Pressure Relief Valve DBW30A1N5X/315-6EG24N9K4/12 - Bosch Rexroth R900969817

When the system pressure has to be reset while the machine runs, a screwed cap only gets in the way. The pilot-operated pressure relief valve DBW30A1N5X/315-6EG24N9K4/12 in size 32 is set through a rotary knob instead, across a range of 4 to 315 bar.

Benefits

• Setting through a rotary knob, so the limiting pressure changes without a tool.
• Adjustment range 4 to 315 bar at a maximum operating pressure of 350 bar.
• Up to 650 l/min through the size 32 port pattern ISO 6264-10-17.
• Pilot-operated poppet seat valve that loses no oil across a clearance when closed.
• Solenoid unloading at 24 VDC, two switching positions to symbol A, 6.5 kg.

Applications

On test rigs, in toolmaking and with changing workpieces the required system pressure often differs from job to job. A rotary knob cuts that change to a few seconds, where a capped internal hexagon calls for a tool and for removing the cap. Because the valve is pilot-operated, the pressure difference stays flat across the whole flow range up to 650 l/min.
