Top Assembly Rotation
(cont'd.)
7.
Remove the two body bolts [4] screwed up
from the bottom (were partially unscrewed in
step 5).
8.
Carefully rotate top assembly to the desired
position in a plane parallel to the top of the valve
body casting.
Rotate the top housing about 30°
beyond this position, and then rotate it back.
Reposition the top housing back down onto the
valve body casting. This should align the open/
shut indicator with its window and provide proper
alignment of the internal mechanism.
9.
Realign holes in valve body casting with the
corresponding tapped holes in the bottom of the
top assembly housing. Be sure the gasket is still
in place between the body and top housing.
10. Reinsert the body bolts up from the bottom
through the body and carefully engage threads of
the top assembly. Tighten securely.
11. Reconnect conduit and electrical leads, then
check that signal switch wands are properly
positioned and that open/shut indicator moves
freely.
Failure to correct any such misalign-
ment can result in extensive damage to the
internal mechanism of your valve.
12. Energize valve and cycle several times from
closed to full open position. Also electrically trip
the valve in a partially opened position to prove
valve operates properly.
13. Replace and secure side cover access plate
and place valve in service.
Four top assembly positions are available for
most Maxon valves. When looking at the open/shut
window indicator of an electro-mechanical valve
assembly, the motor (for motorized version), or the
operating handle (for manual version), will be on the
right side of the top assembly. The valve body is on
the bottom. From this view, the unidirectional valve

in direction of fluid flow: to the right (position "R"), to
the left (position "L"), towards you (position "TO") or
away from you (position "AW"). With smaller size
swinging gate valve bodies, only position "R" and
position "TO" may be used.
