Standoff Assemblies
Valves which will be installed in ovens
or heated zones require a standoff
assembly, which locates the actuator
out of the heated zone and supports
both the valve and the handle or
actuator. The 5/8" outside diameter
standoff tube extends through the
oven wall and is secured by means of a
clamp ring supplied with the assembly.
If you are converting an actuated
valve from a closemount to a standoff
application, order the appropriate
clamp ring and two screws in addition
to the standoff assembly. Consult the
factory for availability of non-standard
lengths.

Converting from
closemount to a
standoff
If you are converting an
actuated valve from a
closemount to a standoff
application, the clamp
ring and screws which
secure the standoff to the
actuator are
not included
in the standoff assembly.
Order clamp ring and
screws in addition to the
standoff assembly.
tech tip
If you need the
actuator
as well as the hardware
,
you can order it complete
with the appropriate
hardware or with the
required standoff already
installed.

more information
For illustrations of
standoffs on valves and
actuators, see pages
206-207.
The microelectric actuator for
selectors uses a special standoff
assembly (SOMMP) which is keyed
to both valve and actuator. The
key guarantees proper alignment
and positioning of the valve.
Product numbers show the most
common length of standoffs: 4" for
air actuators and manual knobs, 2" for
microelectric and standard electric
actuators. Standoff assemblies
are available in lengths of 2", 3",
and 6". To order a 6" standoff
instead of a 4" one, change the 4
in the product number to a 6.
