I'm sorry. I messed up. Your valve is the updated one. I have a picture of my updated valve. It matches the #1 in your attached illustration. Indeed, your #2 was what I hacked up for my "straight through" valve. Second pic is a side by side of old "throat cleared" valve and updated one. And sorry again for pulling off track. My bad. I don't have picture of old valve before surgery began.
