Ft. Lbs. Nm 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 con-
trol valves is not symmetrical, 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 necessary, rotate the valve 180 degrees.
