This is the Atlas Copco throttle valve part number 3121500999, Crowder SKU AC-3121500999. It is part of the operator control on the rock drill. Because it is handled every cycle of every shift, wear here is felt as a vague or sticky trigger long before the machine stops.
It appears on the RH 658L/LS/LS-01 Rock Drill breakdown. That machine is the RH 658 L Surface Rock Drill if you are pricing a replacement rather than a repair. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
Work through the rest of the assembly on the same breakdown, or start over from the parts breakdown index. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
