Tipton almost added another seconds later but his left-foot shot was well saved by Vale goalkeeper Chris Martin.
Port Vale offered precious little all evening with striker Doug Loft missing the only chance of the first half blazing the ball over the bar after 21 minutes.
The game was sealed midway through the second half when 20-year-old giant midfielder Hamza Bencherif rifled home a 20-yard volley after his first shot had crashed back to him off the crossbar.
Bencherif had clearly got a taste for goal raining in two further strikes in the dying stages that tested the Martin from long range. Marc Richards had a chance for the visitors late on when he sent a fizzing free kick inches past the upright.
