SOLUTIONS

TECHNOLOGY

PROVENEXPERIENCE

Many valves are marketed for critical servicecontrol but few can provide the complete solution

needed for the grueling conditions of severeservice. The DRAGlOOD valve was designed

solely for this purpose to meet your specificcontrol valve needs. Whatever your application, forsevere service control, there is only one intelligentchoice: CCIs DRAG

lOOD control valve.

The DRAGlOOD control valve provides the

complete solution because it eliminates problems ofcavitation, noise, erosion and vibration byeffectively controlling fluid velocity.

The technologically advanced design of the DRAG

disk stack trim controls fluid velocities by forcing thefluid through a series of right angle turns, the exact

number of turns is scientifically calculated toachieve low fluid velocities consistent with theneeds of the application. This assures long, trouble-free control valve life

CCI has more than 20 years of experience servingthe critical service control valve needs of the power,petroleum, chemical, pulp and paper, and marineindustries Today's DRAG

valves combine this

experience to work for you to provide the followingkey benefits

Increased plant productionn Proven, highly reliable valve performance and

longer intervals between maintenance.

Lowest overall costn Easy maintenance quick change trim, no

screwed or welded seats.n Long trim life.n Elimination of damaging cavitation, noise and

pipe vibration.n Custom valve designs to fit your piping

constraints. Fewer valves, needed because theDRAG

valve can often do the job of multiple,

parallel valves.n Reduced leakage costs. Tight shutoff prevents

heat loss due to seal and seat leakage.n Reduced system costs: In many applications,

block valves, orifices and/or multiple controlscan be eliminated.

APPLICATIONSCCIs DRAG

lOOD control valves have been used in thousands of

severe service applications worldwide. They are designed to handle highpressure liquids and gases such as steam, water, petroleum products,and chemicals. Years of research and experience innumerousapplications have proven the superiority of the DRAG

valve in critical

applications. So much so, that the DRAGvalve is the only valve that

many companies will install in applications crucial to their plantsoperation. And, even if your application is not a critical one, monetary

savings justify your choice of the DRAGvalve. The list below identifiessome typical DRAG

The DRAGValve Concept

CCIs patented DRAGdisk stack controls flowingvelocities throughout the valve trim by forcing the process fluidto follow a tortuous path of right angle turns. The resistance toflow provided by these turns (or stages) limits the trim exit

velocity to a safe level, regardless of the pressure drop. TheDRAGvalve eliminates problems resulting from excessivefluid velocities such as trim and body erosion, noise, vibrationand poor process control.

The fluid path through the trim is a series of expandingpassage grooves in a metal disk (see Figure 2). The 90-degree turns in the path reduce the pressure in many steps, tomaintain control of the fluid velocity at all points throughout thetrim. By varying the number of turns, the DRAGtrim is

designed to control the damaging velocities in your specificapplication.

DRAGvalves also eliminate the need for downstreamorifices because they control velocity in the valve.

The flow path in the DRAGvalve trim is intentionally

designed quite small to optimize its pressure reducing qualities.However, when contaminated fluids must flow through theDRAGvalve, the trim is made with thicker disks, larger, deeperpassages, and multiple inlet ports to prevent blockage.

Key Design FeaturesFlexible Characterization

By combining CCIs unique capability to easily vary thenumber of turns in each disk passage, the number of passagesin each disk, and the number of disks in each stack, CCI has an

ability unequaled in the industry to meet your most demandingflow characterization and rangeability requirements.

Exceptional ShutoffCritical service valves often need exceptional shutoff

performance to withstand long periods of closure at high-

pressure drops. Proper valve plug style, seat design, andseat and gasket loading are critical elementsthat make the difference between properoperation and premature valve failure. Throughthe use of computer analysis, we ensure that the

DRAGlOOD control valve meets your shutoffchallenge with what we believe are the higheststandard seat loads in the industry.

Stable Process ControlCapacity can be varied for each of the

disks in the disk stack. Not only is the velocitycontrolled, but the fluid flow capacity is alsomatched to your system design requirements to

guarantee stable control.In addition to the disk stack, stable control

is also achieved by other unique DRAGtrimdesign features. Standard DRAGdisk stackshave pressure equalizing ring (P E R) grooves

built into them (see Figure 3) and each disk is

made with a land on the I.D. so that localizedpressure from each disks outlet is equalizedaround the plug This eliminates radial forces on the plug,which might otherwise cause binding in flow under-the-plug

applications and/or radial vibration and buffeting in flow over-the-plug applications.

CCIs packing box configuration and packingprocedures provide minimum sticking with superior sealabilityin high pressure, high temperature services. The close

tolerance between the spacer, follower, and stem preventspacking extrusion at pressures up to 9,000 psi (600kg/cm2).The result is smooth, stable control of the variable, such aslevel pressure, temperature or flow.


6/11

Better Flow Control with Fewer ValvesWhen exceptionally low flow is required along with

high rangeability, the disk stack can be provided withlabyrinth grooves at the bottom. These grooves providea restriction to annular flow (generally ignored by othervalve manufacturers) so that the minimum controllableflow is significantly reduced.

In combination with our ability to characterize theflow, it is possible for CCI to provide true throttlingrangeability in excess of 100:1. In new system designsthis can often result in the elimination of smaller

parallel start-up valves (such as those used infeedwater control of power plants), saving the pipingand installation costs of these valves.

Accessories Matched To performance RequirementsThe selection of proper accessory hardware is

also critical to proper valve performance. Positioners,position transmitters, limit switches, etc. are selected toprovide the quality and performance necessary forsevere service applications.

Computerized engineering analysis enables theCCI Engineer to select quality accessories to assurethat stroking speeds, failure modes, and otherperformance criteria such as resolution and linearitywill be achieved not only on our test benches, but inyour plant as well.

Valve Plug ConfigurationsDRAG

lOOD control valves use one of three bas

plug configurations tobest suit theapplication. They arean unbalanced plug, abalanced plug, or apressurized seat plug.Their typicalapplications areoutlined below.

Unbalanced PlugAn unbalanced plug

(see Figure 4B) is usedwhen unbalancedforces (due to the valveplug area and pressuredrop across it) arerelatively small, or forspecial cases where abalanced plug sealmaterial is not compatible with the process fluid.Due to typically large unbalanced forces in high predrop situations (forces that must be controlled by thactuator) this design is limited to small valve plug sior less). ANSI Class V or Class VI (with soft seat) is

achieved.

Balanced PlugThe balanced plug is the most commonly used valvconfiguration (see Figure 5). It uses axial holes to cthe top and bottom ends of the plug to provide equal pon both sides of the plug. This pressure balancingsignificantly reduces the force required by the actuaA balance seal is used around the plug to prevent lealong the outside of the plug. For services to 450

0F

(2320C) a self-energizing fluorocarbon balance seal

used, whereas for services to 10500F (565C) a con

compression graphite balance seal is used (see FigThe shutoff achieved through this construction, inconjunction with proper actuation, is:

Teflon (TFE) balance seal, TFE seat - ANSI Clas Teflon (TFE) balance seal, Metal seat - ANSI ClaV MSS-SP-6 1

Graphite balance seal, Metal seat - ANSI Class I
