NOTE: When removing control valves from the manifold, it is important to observe the tag on the
face of the valve, as the new valve must be installed with the tag facing the same way as
the tag on the valve that was removed. The bolt pattern on the control valves is not sym-
metrical, so if the bolts seem difficult to turn when installing, it would indicate the valve is
upside down and forcing the bolts will result in cross-threading. Check the tag, and if neces-
sary, rotate the valve 180 degrees.
