Not sure how WD-40 will react to heat so you may want to keep an eye on the valve. WD-40 does have some petroleum based solvents but since it is mainly a water displacement and rust preventive product rather than a lube maybe the solvents are no worse than kerosene and not concentrated enough to cause issues. Maybe pick up a graphite based lock lube and give the valve a couple of applications just to be on the safe side.
