Ordering by number: this is F011476 (also carried as 3310103399), the Chicago Pneumatic throttle valve – complete. It governs how air reaches the working end of the hammer. Wear on the sealing land is the usual cause of a throttle that leaks with the trigger released.
It is called out in the parts diagram for the FL 0025 VR SVR Pick Hammer and FL0022S FL0022 Clay Digger, and on 1 other machine. Check it against the reference number on the diagram first; serial breaks change what fits.
Use the full diagram library to work through the rest of the assembly, or the Chicago Pneumatic lineup if you are pricing a replacement machine. Stocked in Denver orders placed by 4 PM ET ship the same day when the part is on the shelf.
