Patent ID: 7523787

Claim:
A reverse out valve comprising: an outer housing; a mandrel slidably disposed within the outer housing and forming a bypass region therebetween, the mandrel having a central flow path with a valve seat positioned therein and first and second side wall ports positioned on opposite sides of the valve seat; and a valve element positioned in the central flow path, the valve element and the valve seat having a one way valve configuration wherein fluid flow in a first direction relative to the central flow path is substantially prevented, the valve element being axially moveable relative to the valve seat to allow fluid flow in a second direction relative to the central flow path; wherein the mandrel is axially movable relative to the outer housing between first and second positions, in the first position, a bypass passageway is formed between the first and second side wall ports via the bypass region thereby allowing bypass flow around the valve element and the valve seat and, in the second position, bypass flow is prevented; and wherein the outer housing includes an indicating collet that allows a predetermined force in the first direction to operate the mandrel from the first position to the second position and wherein the indicating collet allows a predetermined force in the second direction to operate the mandrel from the second position to the first position.
