Abstract
A curved flow tube can be positioned in a tubing string deployed downhole in a wellbore to slow a closure of a flow valve in the tubing string. The tubing string can be deployed in the wellbore to transport wellbore fluid. The flow valve can be coupled to the tubing string. Additionally, the flow valve can include a flapper and the flow tube. The flapper can be positioned to control the wellbore fluid transported through the tubing string. The flapper may be adjusted between an open position and a closed position. The flow tube can include a downhole end that has a curvature to slow a closure rate corresponding to adjusting the flapper from the open position to the closed position.
