Some of the waste tank deodorizer products say they lubricate the valves. I don’t know how effective they are. I have had relatively good success in just lubricanting the metal shafts with either a spray silicone lube or a grease. WD40 is a good cleaner but not a lube. There really isn’t much you can do when the valve is in the closed position.
