If it's a Dupre valve and the gasket hasn't been replaced in a long time it could be the gasket either swollen or popped out of the metal plate and not allowing it to drop completely to form a seal. Or possibly a piece of gasket has torn off and fallen into the groove at the bottom of the valve body.
Here are a couple webpages with info on the Dupre valves and a post with info on the valves:
