a poppet configured to control a fluid flow through the flow port; a piston rod, disposed uphole from the poppet, configured to move the poppet past at least part of the flow port, wherein the piston rod comprises: an upper exposed piston area exposed to an internal volume of the insert valve; and a lower exposed piston area exposed to the internal volume of the insert valve, wherein the piston rod translates, at least partially, in a piston bore; a hydraulic control port configured to control movement of the piston rod; a piston seal, disposed on the piston rod, that separates the piston bore into an upper piston bore and a lower piston bore; an upper rod seal that isolates the upper piston bore from the internal volume of the insert valve; and a lower rod seal that isolates the lower piston bore from the internal volume of the insert valve. ### Claim 2 (depends on 1) The insert valve of claim 1, wherein the hydraulic control port is in a first fluid contact with the upper piston bore. ### Claim 3 (depends on 2) The insert valve of claim 2, wherein the insert valve further comprises a pressure chamber that is in a second fluid contact with the lower piston bore. ### Claim 4 (depends on 3) The insert valve of claim 3, wherein the pressure chamber at least partially circumscribes a volume around the insert valve. ### Claim 5 (depends on 1) The insert valve of claim 1, wherein the insert valve further comprises a spring that exerts an upward force on the poppet. ### Claim 6 (depends on 5) The insert valve of claim 5, wherein a first pressure in the upper piston bore causes a downward force on the piston rod greater than the upward force of the spring. ### Claim 7 (depends on 6) The insert valve of claim 6, wherein a second pressure in the lower piston bore causes a second upward force on the piston rod such that a net downward force on the piston rod is less than the upward force of the spring. ### Claim 8 An insert valve installed, at least partially, in a safety valve, comprising: a flow port disposed on an exterior of the insert valve; a poppet configured to control a fluid flow through the flow port; a piston rod, disposed uphole from the poppet, configured to move the poppet past at least part of the flow port, wherein the piston rod comprises: an upper exposed piston area exposed to an internal volume of the insert valve; and a lower exposed piston area exposed to the internal volume of the insert valve, wherein the upper exposed piston area is greater than the lower exposed piston area; and a hydraulic control port configured to control movement of the piston rod. ### Claim 9 (depends on 8) The insert valve of claim 8, wherein a pressure in the internal volume of the insert valve causes a net downward force. ### Claim 10 (depends on 8) The insert valve of claim 8, wherein the insert valve further comprises a spring that exerts an upward force on the poppet. ### Claim 11 (depends on 10) The insert valve of claim 10, wherein a pressure in the internal volume of the insert valve causes a downward force on the piston rod greater than the upward force of the spring. ### Claim 12 An insert valve of installed, at least partially, in a safety valve, comprising: a flow port disposed on an exterior of the insert valve; a poppet configured to control a fluid flow through the flow port; a piston rod, disposed uphole from the poppet, configured to move the poppet past at least part of the flow port, wherein the piston rod comprises: an upper exposed piston area exposed to an internal volume of the insert valve;

a poppet configured to control a fluid flow through the flow port; a piston rod that translates, at least partially, in a piston bore and is configured to move the poppet past at least part of the flow port, wherein the piston rod comprises: an upper exposed piston area exposed to an internal volume of the insert valve; and a lower exposed piston area exposed to the internal volume of the insert valve, wherein the upper exposed piston area is greater than the lower exposed piston area, and wherein a pressure in the internal volume of the insert valve causes a net downward force; and a piston seal, disposed on the piston rod, that separates the piston bore into an upper piston bore and a lower piston bore; a hydraulic control port in a first fluid contact with the upper piston bore;
