Have you tried applying heat? Either with a heat gun or with a torch. Be careful if using a torch to not overheat it, don't want to melt the o-rings or valve seat. After applying heat for a while to get it hot then spray a penetrating oil on it and try to unscrew it. Maybe try doing this a couple times.
