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
