The Kilmurry side conceded the first two points against last year’s intermediate champions but settled into the game with Caoimhe Creedon leading the line well for Vals.
Creedon scored a pair of first-half goal as Vals posted 2-9 before a youthful Éire Óg scored their third point of the day in reply.
Eimear Scally led the way for Éire Óg but Briege Corkery and Louise Coholon dominated the middle for a relentless Vals, for whom Creedon and centre-forward Jean Lucey topped the scoring stakes, as they ran out 4-16 to 0-6 winners.
However, the headline act of yesterday’s ‘feast of football’ in CIT was the senior B final between Mourneabbey and Clonakilty, a game which turned into the O’Sullivan show.
The youngest of the O’Sullivan sisters, Doireann, put Mourneabbey into an immediate lead with a goal, although Jenny Quinn netted in reply. However, a goal by Laura Fitzgerald was followed by a 25th-minute Ciara O’Sullivan green flag which helped the favourites to a 3-6 to 1-2 half-time lead.
Clonakilty put in a spirited performance and managed to halve the deficit in the second half, with Ciara McCarthy netting. However, Mourneabbey ran out deserved winners, 3-11 to 2-7, with Roisín O’Sullivan lifting the trophy while sister Ciara was named player of the match.
Meanwhile, Douglas and St Michael’s will meet in the junior B final, Douglas comfortably defeated Dromtarriffe (6-12 to 1-10) while their city neighbours beat Mallow (1-11 to 2-3).
In the junior C semi-finals, Lisgoold took victory over Muintir Bhaire (5-6 to 1-6) and Bishopstown overcame the challenge of Castlemagner (3-9 to 2-8).
