Installation on Actuator
Orientations, Normal and Reverse Acting
Normal acting
is full CW when the process valve is closed and CCW when the process valve is open.
Reverse acting
is full CW when the process valve is open and CCW when the process valve is closed.
90° indicator dome assemblies are design to accommodate any mounting arrangement and can be adjusted up to
9° off axis if needed. 45° indicator dome assemblies can only accommodate
normal acting
applications that are
mounted parallel ±9°.
Consult your local distributor or factory representative for 45°
reverse acting
or
mounted
perpendicular
applications.
Illustration #1:
The image to the left
shows a Valvetop unit
mounted
parallel
to the process valve in the closed position.
The green arrow at the top shows the “
normal acting
”
direction of travel to open the valve. This is the standard
orientation and your unit unless otherwise specified will
be factory set to operate in this fashion.
Illustration #2:
The image to the right
shows a Valvetop
mounted
perpendicular
to the process valve in the closed
position. The green arrow at the top shows the
“
normal acting
” direction of travel to open the valve.
Notice that the indicator dome has been rotated 90°
compared to the unit above.
