counterclockwise rotation will lengthen actuator stroke (stroke > 90°).
Installation
Relieve all pressure from the actuator.
Loosen Travel Stop Nut(s) on Travel Stop(s) A. Be careful not to misplace the
travel stop O-ring(s).

With pressure still applied to P3, tighten the travel stop nut until it
comes in contact with the end cap, then an additional quarter turn.
