PEWSEY recorded their first win at Ringwood since joining the Sydenhams League.
Vale took the lead when when Jack Hopper's free kick was headed on and Ricky Franklin slotted home.
Vale keeper Louie La Touché made a couple of good saves, but it was Pewsey who extended their lead before half time as Franklin fired home his second.
Dan Sloan's third after the break seemed to have wrapped things up for the visitors, but Liam Taylor pulled one back for the home side.
Tom Ritchie sealed the points for Vale before Sean Leadbetter's consolation.
