Valve carries Chicago Pneumatic part number R085897, which also shows up as 3310103522 and is stocked here under CP-R085897. It directs the flow that reverses the piston in the rock drill. Valve wear changes port timing, and the machine loses blow rate before it loses the ability to run.
It appears on the CP 9 9S Rock Drill and CP 9A 9F Rock Drill, and on 3 other machines breakdown. 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.
