Valve alignments – VICI Selectors (multiposition) Standard electric User Manual

Basically, this procedure is a method of centering the perpendicular engrav-
ing on the selected port by determining the point at which flow begins (when
the engraving just starts to intersect the port) and the point at which flow
ends (when the engraving ceases to intersect the port), and centering the
rotor between those two points.

1. Plug the actuator in. If the position indicator doesn’t read “1”, flip the

switch to the HOME position.

2. Place the valve or valve and standoff combination on the actuator.

By convention, the factory alignment places the common port(s) at
12 o’clock. Re-orienting the standoff or the slotted coupling (in close-
mount applications) on the square drive of the actuator allows three
other possibilities.

For a valve on a standoff, make sure the standoff butts all the way
against the actuator so that the drive mechanism is completely engaged.
Tighten the clamp ring screw enough to keep the standoff from falling
out when it is released, but make sure it is loose enough to allow the
assembly to be turned during the alignment procedure.

For a closemount valve, make sure that the ends of the pin in the rotor
are engaged by the slots of the coupling. Tighten the clamp ring screw
enough to keep the valve from falling out when it is released, but make
sure it is loose enough for the valve to be turned during the alignment
procedure.
