1. An assembly comprising:
a first port to communicate hydraulic fluid with a first fluid conveyance line;
a second port to communicate hydraulic fluid with a second fluid conveyance line;
a first-end stop proximate a first end of a bore of the assembly;
a second-end stop proximate a second end of the bore;
a seal moveable in the bore of the assembly between the first-end stop and the second-end stop to communicate pressure between the first port and the second port;
a pilot fluid conveyance line; and
a pilot-to-open valve operably connected to the first port, the second port, and the pilot fluid conveyance line, the pilot fluid conveyance line being configurable to apply pilot pressure to the pilot valve, the pilot pressure being capable of bypassing the seal by communicating pressure between the first port and the second port.
