CV500 Valve
June 2017
CAUTION
When ordered, the valve configuration and construction materials were selected to meet particular pressure, pressure
drop, temperature, and controlled fluid conditions.
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
office or Local Business Partner.

Key numbers are shown in figure 9 for NPS 3 through 8 and in figure 10 for NPS 10 and 12.
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 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 2.
