Abstract: A gas turbine engine comprises a bleed duct for receiving bleed flow and a plurality of valve members pivotable relative to the bleed duct for variably controlling fluid flow along the bleed duct. The gas turbine engine also comprises an actuation mechanism for pivoting the valve members relative to the bleed duct, wherein the actuation mechanism is configured such that pivoting of the valve members is staggered.
