D2 DRAG® 900D Control Valve
CCI’s Unrivalled Expertise
CCI’s DRAG® technology, pioneered in 1961, is the industry’s leading solution
for handling demanding service conditions. The 900D is designed to deliver
peak process performance with superior control while minimizing losses
caused by valve leakage. CCI’s proven DRAG® technology will reduce your
equipment and maintenance costs through dramatic reductions in cavitation
and vibration – the root cause of damage to trim, adjacent equipment and
piping. Supported by the world class technical expertise of The Valve Doctor®
program, the 900D is a continuation of CCI’s industry leading severe service
solutions that customers have come to depend on.

3Performance You Can Depend On
Control and Reliability
The 900D continues CCI’s tradition of customizing valve performance
to meet the exacting requirements of your application. In addition to
linear and equal percentage characterization, the 900D can be custom
characterized for applications that require critical control.
Figure 1 is an example of a pump application that has a pressure drop
that varies with flow. This example shows how pressure drops are
highest at start up, and then decrease as the required flow rate increases.
Figure 2 depicts how CCI improves control and reliability by applying
the appropriate number of pressure reducing stages through the entire
range of flow conditions. The result, as shown in Figure 3, is extremely
consistent trim exit velocity throughout the entire stroke range of the
valve. Uncontrolled trim exit velocities, common in single stage designs,
can lead to excessive trim damage as shown in Figure 4. The 900D
provides superior control and reliability, thereby significantly extending
the operating life of the valve.
The lessons learned from this example apply to applications that handle
gas or liquids. See page 2 for industries and applications.
The 900D’s DRAG® Technology Delivers:
n Control that improves plant efficiencies
n Reliable performance
– Due to reduced damage and decreased maintenance frequency
– Consistent energy control across all flow conditions
The ability to be custom characterized enables the DRAG® disk stack to
have variable staging throughout the entire stroke.

D4 Control Your Process
Noise and Vibration:
Noise and vibration are pervasive in applications involving throttling or
venting of compressible gases. Frequently, these problems can be avoided with
the selection of a valve that can properly control the kinetic energy of the fluid
during the pressure letdown process. CCI encourages the process industries to
adhere to ISA guidelines for valve trim exit kinetic energy in order to ensure
noise and vibration problems are avoided.
900D Solves Vibration:
CCI has extensive experience in helping customers eliminate the
damage that is a result of vibration. Figure 5 shows the dramatic results
of applying DRAG® technology and kinetic energy control. Customers
typically experience a 90% decrease in peak vibration with the application
of DRAG®, and that enables them to:
n Eliminate valve and piping damage
n Minimize system trips
n Minimize downtime and maintenance costs
n Eliminate additional piping supports
900D Solves Noise:
CCI’s philosophy to noise control is to avoid the creation of noise as
opposed to trying to muffle it once it’s produced. With the 900D the
amount of noise that must be absorbed by the pipe wall or insulation is
dramatically reduced, and the noise sensed in the vicinity of the valve is at
acceptable levels.

Figure 9: Seat ring damage caused by cavitation results in leakage that reduces plant efficiency and increases operating costs
Cavitation
Cavitation, a common cause of structural damage in control valves,
is the rapid formation and collapse of vapor pockets. This violent
phenomena can produce surface stresses greater than 200,000
psi (1,400 MPa), consuming even the highest hardness trim
materials. Trying to compensate for cavitation with the addition of
hard surface treatments is a temporary fix that only incrementally
increases the life of the trim. The key to increasing trim life is to
eliminate the root cause of cavitation, excessive trim velocities. CCI
adheres to the ISA guidelines for trim exit velocity.

n Maintains the fluid velocity at minimum levels so that local
pressures are unlikely to drop below the fluids vapor pressure
n Should gas bubbles form, DRAG® reduces the energy to a safe level
by dividing the flow into many small channels
n The 900D adheres to ISA guidelines on trim exit velocity
Impact of Cavitation:
The trim damage that is the result of cavitation can adversely affect the
performance of the plant. Many applications require that the control
valve have fine control or tight seat leakage performance. When a trim
is damaged by cavitation these attributes can be negatively impacted
resulting in:
n Noise and vibration
n Trim damage
n Poor control
n Increased seat leakage
n High maintenance costs and downtime
