Assuming power to the solenoid = what you want to operate is on. Ports A and B are connected , port C is blocked.
No power to sol = item off. Port A is blocked , Ports B and C are connected ( this bleeds off vacuum at item B.

By the time you've found something that works and fits or have made it fit plus its price/shipping might as well have bought the stock item. Hence the question still stands: what goes wrong -wears out or breaks- inside the old valve and can it be fixed?
