The achievement came alongside teammate Martin Perry in the men’s class 14 event at the ITTF World Para Elite Beijing.
Shilton said: “Another great tournament for Martin and me and so pleased to win our third tournament in a row.
“We have worked so hard in the doubles with Rushy (head coach Andrew Rushton) and to see it all paying off is really reassuring.
“The semi-final was great – we had a really good match against them in Slovenia and it was good to prove that we could beat them again – and the final was also really good as we lost to them in the group.
“I really believe we are one of the best teams in the world and these results prove that.
“Now it’s all about getting back to the training hall and improving even more to be ready for the World Championships.”
The British pair defeated North Korea’s Kim Yong Rok and Pak Kum Jin 3-2 in a tense final, edging the fifth set 11-6 after the match was drawn level at 2-2.
Perry said: “Amazing to get to our fifth consecutive final and our third consecutive tournament win and our second Elite on the bounce as well.
“We know we are one of the top teams – we’ve gone out there and proved it – so I’m super proud of Billy and me.
“It was a great performance from both of us, and I felt that Billy was just fantastic from start to finish which made my life so much easier.
“That’s us qualified for the World Championships now and hopefully we can continue the winning streak. It was good to get the win over Thailand 3-1 because in Slovenia it was a lot tighter and they are a top team.
“To get the win over North Korea in the final after losing to them so narrowly in the group was also really good – it was a hard-fought match against two players we’ve not seen before and thankfully we managed to get the job done and get the win.”
