Hi, does anyone know if it is possible to use one spunding valve on two fermenters? I am planing to ferment under pressure on two fermenters, but I only have one spunding valve. The two batches are gong to be identical, but brewed one day aften the other. Will it work to use a line from each fermenter into the same spunding valve?

That should work but I can't see a way to plumb it that isn't either more expensive than a valve, or just a mess. It sure would be cool if they made a spunding valve that would screw into a ball locks lid PRV socket though! Then you could just connect your two gas posts and be done.
I did this on my latest batch. Worked fine with no issues. You'll need some additional hardware though.
In my case I ferment in kegs and want 19L/5G finished beer in my purged serving keg (on the right). So I ferment 23L/6G spread across the 2 kegs on the left (28.5L/7G total which allows some headspace). The smaller keg has a carbonation lid which works as a second gas post on the keg. This allows me to link the 2 kegs together via the gas posts, then link the fermentation keg gas post to the serving keg liquid post, then the spunding goes on the serving keg gas post.
By the time you buy the carbonation lid (good value on AliExpress) and the hoses it doesn't work out much cheaper than a second spunding, but I'm mainly interested in having both fermentor kegs purge the serving keg. Plus adjusting spundings sucks and I'd rather just deal with one of them.
Obviously the keg lid solution is only going to work if you ferment in kegs, so here's another idea for you.
Make a hose with gas disconnects on both ends. Cut the hose in half and join it back together with a T connector. On the T connector, add a carbonation cap (the kind that has a barb on the underside). Connect your spunding to the carbonation lid and the gas disconnects to your keg. I don't have a picture of this setup. This hose setup also functions super good as a 2-way adapter when you need to take 2 kegs to a party, of just use it as a gas-gas hose for closed transfers.
