Abstract
A downhole tool includes a tubular having an outer surface and an inner surface defining a flowbore having a longitudinal axis, and a backpressure valve arranged in the flowbore. The backpressure valve includes a flapper valve having a first side and an opposing second side pivotally mounted to the inner surface to selectively extend across the flowbore and a locking system mounted to the inner surface in the flowbore and snap-fittingly engageable with the flapper valve. The flapper valve is pivotable between a first position, wherein the flapper valve is free to pivot relative to the inner surface, and a second position, wherein the flapper valve is pivoted away from the flowbore and locked open by the locking system such that the first side forms part of the flowbore.
