Hey Paul,
Unfortunately I do not have a way of knowing what originally came on the Keystone to know the exact replacement. Luckily the valve sizes are standard. If you are able to send me a photo of the one you are wanting to replace I can make sure to match it up with a good replacement. If you are able to get a part number or model number off of yours as well I can find the right replacement.
If you are able to get any of that information let me know and I will get looking for the right replacement.
