The perfect afternoon conditions allowed both sides to throw the ball around in an entertaining encounter, and they exchanged quickfire tries through Scott Prince's effort for the Titans, before Tighe added his second after latching onto Clint Newton's popped pass.
But on the stroke of halftime, Michael Jennings darted over for his ninth four-pointer of the season as the Titans' defence was caught flat-footed by Walsh's grubber-kick.
John Cartwright's side closed the gap seven minutes after halftime when Zillman took advantage of some soft defending to dance over the line for his sixth try in as many games.
However, Prince was unable to level the scores when he missed the conversion, and Penrith iced the result with two tries in two second-half minutes.
Josh Mansour, who has enjoyed an encouraging first season, combined brilliantly with Jennings on the left wing to race to the line, and the NSW star scored his second of the game following a superb Walsh pass.
Tighe added some extra gloss to the scoreline with his hat-trick seven minutes from time, before Mark Minichiello grabbed a late consolation for the visitors late in the game.
