I have worked on many Fuller valves at this point and most of them do not have terrible wear in the stems. The balls are all corrupted and the seats need to be honed but the stems are, more often than not, in fair condition. From this I conclude that they were set up to not be forced.The main weakness of the valve, according to Brian, is that it can trap debris floating in the water which could indent the ball, causing a leak. With the compression design, this sort of damage is less likely.
