Very likely. Fresno ag has an extensive variety of faucet and shower valves in stock. my experience in replacing Pfister shower valves is the type where the hot and the cold have seperate valves and a shower diverter valve in between. They are large 4 to 5 inches long. Best to take the valve you wish to replace to the store as there are at least three variants. If you are replacing this valve you may get by with replacing the rubber washer and the valve seat which is a replaceable brass part that Fresno ag does carry. ALWAYS remove and possibly replace the valve seat. It deteriorates after tens of years and chews up the rubber washer. It is the surface that the valve washer presses on
I don't know you can call them and ask.
