Valve Alignment
When the valve arrives from the factory installed on an actuator, it is
accurately aligned and ready for use. However anytime the clamp ring on
the actuator is loosened, as when removing the valve from the actuator for
mounting through an instrument panel or oven wall, the valve and actuator
must be realigned so that the internal ports and flow passages on the rotor
intersect properly.
CAUTION: Before removing the valve from the actuator,
mark the factory alignment position of the valve.
CLOSEMOUNT: Make temporary registration marks on
the face of the valve where it lines up with the slot in the
stainless clamp ring on the actuator.
STANDOFF: Make temporary registration marks on the
standoff tube where it lines up with the slot in the black
anodized clamp ring on the actuator. Do not remove the
valve from the standoff assembly.
When this mark is lined up with the slot on reassembly,
the factory alignment will be approximately reproduced
as long as the valve and the actuator remain in their
original positions.
Causes of Misalignment
. Removal of valve from actuator for mounting
As referred to earlier, mounting valves through a bracket or oven wall
requires that the valve or valve/standoff assembly be separated from the
actuator. In the case of a valve on a standoff, this is accomplished by loos-
ening the socket head screw (8-32 x 5/8") in the black anodized CR3 clamp
ring on the actuator, using a 9/64 hex driver. (
Figure 6) In valves utilizing
a closemount assembly, the removal is accomplished by using a 7/64 hex
driver to loosen the socket head screw (6-32 x 5/8") in the stainless CR11
clamp ring on the actuator. (
Figure 5)
Any time the screw in the CR3 or CR11 clamp ring has been loosened, the
alignment of the valve after replacement on the actuator should be checked.
The chances of proper alignment after reassembly are greatly enhanced by
following the suggestion in the highlighted note found in the box above.
CAUTION: In some applications it is desirable to delete
the black right-angle mounting bracket supplied as part
of the actuator, as when it is replaced by an oven wall or
instrument panel. For the valve mounting and driving
hardware to function properly, the thickness of the sub-
stitute must approximate the thickness of the bracket.
Consult the factory if problems are experienced.
