Claim 11:
12. A method comprising:
displacing, in response to pressurized force applied by hydraulic fluid, a moveable seal in a bore of an assembly to communicate pressure between a first port and a second port, the first port being used to communicate hydraulic fluid with a first fluid conveyance line, the second port being used to communicate hydraulic fluid with a second fluid conveyance line;
sealing, in response to displacing the moveable seal, an end stop proximate a first end or a second end of the bore with the moveable seal;
preventing, in response to sealing the end stop, hydraulic fluid communications between the first fluid conveyance line and the second fluid conveyance line;
pressurizing a pilot fluid conveyance line, wherein the pilot fluid conveyance line is connected to a pilot valve, and wherein the pilot valve is connected to the first port and the second port; and
communicating, in response to pressurizing the pilot fluid conveyance line, pressure between the first port and the second port, wherein fluid communication between the first port and the second port bypasses the moveable seal.
