This manual for Prince loader valves shows how the detent springs work: http://www.princehyd.com/Portals/0/valves/LVManual.pdf
Page 11 is a center detent. Yours is likely similar.
The balls get forced out into a groove in the detent sleeve. If you can feel the center detent when pushing the lever forwards to drop the loader, then I think that your detent sleeve or its equivalent is worn out in the out (lever down) direction and is letting the spool come out. If you can't feel the detent in either direction then maybe the spring and/or balls are gunked up and not moving.
If it's worn, you probably can't get parts. The easiest thing would be to replace the valve.
Whatever you do, when it's working you should find a new boot and clean and lube the linkage before putting it on. Those parts are often made of pot metal and don't like being exposed to the elements.
