18. A method, comprising:
disposing an insert valve into a borehole with a surrounding pressure, wherein the insert valve comprises:
a poppet configured to control a fluid flow through a flow port;
an upper piston rod coupled to the poppet and configured to move the poppet past at least part of the flow port; and
a lower piston rod coupled to the poppet and configured to exert a chamber piston force on the poppet, wherein the lower piston rod traverses, at least partially, through a chamber,
wherein the lower piston rod comprises:
an uphole piston area; and
a downhole piston area
wherein a chamber pressure, in the chamber, causes the chamber piston force, and
wherein the chamber piston force exerted by the lower piston rod is caused by:
an area difference between the uphole piston area and the downhole piston area; and
actuating the upper piston rod to move the poppet to control the fluid flow through the flow port.
