Product review (5 stars): A whole lot cheaper than a new dryer!
My 12 year old GE Profile gas dryer had developed a slight gas odor in the drum after sitting unused for several hours.  After disassembling the dryer and leak-testing all the gas fittings with dishsoap, I found that there was a very slight leak from the gas jet on the valve.  Ordered this unit to replace it, and removed and cleaned all the pipe fittings with gasket remover in the meantime.  Reassembled with Rectorseal #5 on all the non-flare fittings, and the dryer was back up and running with no leaks or odors in about an hour.  After running a couple of loads of laundry through it then letting it sit overnight, the drum and dryer pass the sniff test -- no gas odor anymore.  Very happy!

I was glad to see that this a Genuine GE part in a GE box, with White-Rodgers labeling on the valve as they manufacture these valves for several different companies.  Keep in mind that all you get is what you see in the picture (gas jet is installed, but no gas line fitting), so you'll need to remove the flare fitting and compression nut from the old valve, clean off all the old sealant, and transfer it to the new valve.  I was expecting this to be troublesome, but some time with a can of automotive gasket remover and an old toothbrush removed all of the old sealant fairly easily.
