1. A system for one or more wellheads, the one or more wellheads comprising:
a first wellhead operably associated with a first wellbore, the first wellhead comprising one or more first wellhead valves and a frac tree operably coupled to the one or more first wellhead valves, opposite the first wellbore;
the system comprising:
a first controller adapted to control a first valve apparatus to pass a downhole tool and/or another object through the first valve apparatus and into the first wellhead;
the first valve apparatus, which is adapted to be operably coupled to the first wellhead, opposite the first wellbore, and is further adapted to be operably coupled to a latch configured to secure a lubricator for deployment and retrieval of the downhole tool on a conveyance string, the first valve apparatus comprising:
an operating volume; and
a valve openable to permit fluid communication between the operating volume and the first wellhead, and closeable to at least partially fluidically isolate the operating volume from the first wellhead;
and
a conduit adapted to be operably coupled to the first valve apparatus between the valve and the latch, and via which the operating volume is pressurizable to facilitate passage of the downhole tool and/or the another object through the first valve apparatus and into the first wellhead.
