1. Spline diameter that connects to actuator versus shaft diameter.
Responsibility for the safety of
process media and compatibility of
valve materials with process media
rests solely with the purchaser and
end-user. Since some valve body/trim
material combinations are limited in
their pressure drop and temperature
range capabilities, do not apply any
other conditions to the valve without
first contacting your Emerson Process
Management sales office.
Key numbers are shown in figure 11 for 3-
through 8-inch sizes and in figure 12 for 10-
and 12-inch sizes.
1. If the valve body (key 1) is to be stored before
installation, protect the flange mating surfaces and
keep the valve body cavity dry and clear of foreign
material.
2. Install a three-valve bypass around the control
valve assembly if continuous operation will be
necessary during inspection and maintenance of the
valve.
3. A Design CV500 valve is normally shipped as
part of a control valve assembly, with a power or
manual actuator mounted on the valve. If the valve

and actuator have been purchased separately or if
the actuator has been removed from the valve,
mount the actuator according to the actuator
instruction manual. Also, adjust the actuator travel
using the Adjusting Actuator Travel procedure in this
manual before installing the valve; the required
measurements cannot be made with the valve
installed.
4. Before starting the actual installation of the valve,
determine the proper installation orientation of the
V-notch ball (key 2) and actuator. Determine the flow
direction of the process fluid through the valve. See
figure 3.
For control valves used in slurry
service, mount the actuator and install
the control valve so that the V-notch
ball rotates above the valve drive shaft
(refer to figure 3), if possible.
5. Before installing the valve, make sure the flow
direction arrow (key 32) on the valve (key 1) matches
the actual process fluid flow direction through the valve
for the application where the valve will be installed.
