Throttle Valve is the American Pneumatic Tool service part carried under part number 1280179539, listed as 19439 before the renumbering. This is control gear it meters air to the rivet buster. A worn control gives creep, hard starting, or a tool that will not shut off cleanly.
It appears on the 133CN T-Handle Rivet Buster and 1133CN T-Handle Rivet Buster breakdown. The tool itself is the APT 133 Pneumatic Rivet Buster. Check it against the reference number on the diagram first; serial breaks change what fits.
