Aspinall led 11-8 at one stage and came from 14-12 down to lead 15-14 only for Van den Bergh to come through and he summed it up afterwards as an emotional rollercoaster.
"I'm so chuffed that I'm through," said Van den Bergh, who now plays Wade. "It was a proper emotional rollercoaster and I'm still in that ride.
"I kept battling and never gave up because today was a such a struggle. I lost the first three sessions 3-2 and went down 9-6, but I kept digging in and believing in myself.
"We didn't perform the way we can but at least I have a chance to improve in the next round, and I will learn from this quarter-final. It's a lesson for me but this week is going very well and I'm playing strong."
