Dalla Valle is on trial at Molde with a view to a permanent switch to Ole Gunnar Solskjaer's side.
The Finnish forward has made just two substitute appearances for Fulham since his switch from Liverpool in 2010 as part of the deal that took Paul Konchesky to Anfield.
Dalla Valle has had spells out on loan at Bournemouth, Dundee United, Exeter and Crewe during the last few seasons and Fulham boss Martin Jol is happy for him to head out again.
"He wanted to play in Holland or Norway, so that's why he's at Molde on trial with view to a loan move," Jol told the Fulham Chronicle.
"He's a young player who is learning his trade. He did well at Crewe, which gave everyone confidence again."
