DRAG® 100D Control Valve
n CCI-THE WORLD LEADER IN SEVERE SERVICE CONTROL VALVES SEVERE SERVICE
Many valves are marketed for critical service control but few can provide the complete solution needed for the grueling conditions of severe service. The DRAG® lOOD valve was designed solely for this purpose — to meet your specific control valve needs. Whatever your application, for severe service control, there is only one intelligent choice: CCI’s DRAG® lOOD control valve.
SOLUTIONS
The DRAG® lOOD control valve provides the complete solution because it eliminates problems of cavitation, noise, erosion and vibration by effectively controlling fluid velocity.
TECHNOLOGY
The technologically advanced design of the DRAG® disk stack trim controls fluid velocities by forcing the fluid through a series of right angle turns, the exact number of turns is scientifically calculated to achieve low fluid velocities consistent with the needs of the application. This assures long, troublefree control valve life

APPLICATIONS ®
CCI’s DRAG lOOD control valves have been used in thousands of severe service applications worldwide. They are designed to handle high pressure liquids and gases such as steam, water, petroleum products, and chemicals. Years of research and experience in numerous applications have proven the superiority of the DRAG® valve in critical ® applications. So much so, that the DRAG valve is the only valve that many companies will install in applications crucial to their plant’s operation. And, even if your application is not a critical one, monetary savings justify your choice of the DRAG® valve. The list below identifies some typical DRAG® valve applications from several industries.

High fluid velocities through the trim are a principal source of severe service control valve problems. The damaging effects of CAVITATION, EROSION, HIGH NOISE and PIPE VIBRATION are typical signs that velocities are not being controlled (see Figure 1). Velocity problems are ® eliminated in the DRAG lOOD control valve.
Key Design Features Flexible Characterization By combining CCI’s unique capability to easily vary the number of turns in each disk passage, the number of passages in each disk, and the number of disks in each stack, CCI has an ability unequaled in the industry to meet your most demanding flow characterization and rangeability requirements.
The DRAG® Valve Concept CCI’s patented DRAG® disk stack controls flowing velocities throughout the valve trim by forcing the process fluid to follow a tortuous path of right angle turns. The resistance to flow provided by these turns (or stages) limits the trim exit velocity to a safe level, regardless of the pressure drop. The DRAG® valve eliminates problems resulting from excessive fluid velocities such as trim and body erosion, noise, vibration and poor process control.
Exceptional Shutoff
The fluid path through the trim is a series of expanding passage grooves in a metal disk (see Figure 2). The 90degree turns in the path reduce the pressure in many steps, to maintain control of the fluid velocity at all points throughout the trim. By varying the number of turns, the DRAG® trim is designed to control the damaging velocities in your specific application. DRAG® valves also eliminate the need for downstream orifices because they control velocity in the valve. The flow path in the DRAG® valve trim is intentionally designed quite small to optimize its pressure reducing qualities. However, when contaminated fluids must flow through the DRAG® valve, the trim is made with thicker disks, larger, deeper passages, and multiple inlet ports to prevent blockage.
Critical service valves often need exceptional shutoff performance to withstand long periods of closure at highpressure drops. Proper valve plug style, seat design, and seat and gasket loading are critical elements that make the difference between proper operation and premature valve failure. Through the use of computer analysis, we ensure that the DRAG® lOOD control valve meets your shutoff challenge with what we believe are the highest standard seat loads in the industry.
Stable Process Control Capacity can be varied for each of the disks in the disk stack. Not only is the velocity controlled, but the fluid flow capacity is also matched to your system design requirements to guarantee stable control. In addition to the disk stack, stable control is also achieved by other unique DRAG® trim design features. Standard DRAG® disk stacks have 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 localized pressure from each disk’s outlet is equalized around 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 overthe-plug applications. CCI’s packing box configuration and packing procedures provide minimum sticking with superior sealability in high pressure, high temperature services. The close tolerance between the spacer, follower, and stem prevents packing extrusion at pressures up to 9,000 psi (600kg/cm2). The result is smooth, stable control of the variable, such as level pressure, temperature or flow.
Better Flow Control with Fewer Valves When exceptionally low flow is required along with high rangeability, the disk stack can be provided with labyrinth grooves at the bottom. These grooves provide a restriction to annular flow (generally ignored by other valve manufacturers) so that the minimum controllable flow is significantly reduced. In combination with our ability to characterize the flow, it is possible for CCI to provide true throttling rangeability in excess of 100:1. In new system designs this can often result in the elimination of smaller parallel start-up valves (such as those used in feedwater control of power plants), saving the piping and installation costs of these valves.

Accessories Matched To performance Requirements The selection of proper accessory hardware is also critical to proper valve performance. Positioners, position transmitters, limit switches, etc. are selected to provide the quality and performance necessary for severe service applications. Computerized engineering analysis enables the CCI Engineer to select quality accessories to assure that stroking speeds, failure modes, and other performance criteria such as resolution and linearity will be achieved not only on our test benches, but in your plant as well.
Valve Plug Configurations DRAG® lOOD control valves use one of three basic valve plug configurations to best suit the application. They are an unbalanced plug, a balanced plug, or a pressurized seat plug. Their typical applications are outlined below. Unbalanced Plug An unbalanced plug (see Figure 4B) is used when unbalanced forces (due to the valve plug area and pressure drop across it) are relatively small, or for special cases where a balanced plug seal material is not compatible with the process fluid. Due to typically large unbalanced forces in high pressure drop situations (forces that must be controlled by the actuator) this design is limited to small valve plug sizes (3” or less). ANSI Class V or Class VI (with soft seat) is achieved. Balanced Plug The balanced plug is the most commonly used valve plug configuration (see Figure 5). It uses axial holes to connect the top and bottom ends of the plug to provide equal pressure on both sides of the plug. This pressure balancing significantly reduces the force required by the actuator. A balance seal is used around the plug to prevent leakage along the outside of the plug. For services to 4500F degrees (2320C) a self-energizing fluorocarbon balance seal can be 0 used, whereas for services to 1050 F (565’C) a controlled compression graphite balance seal is used (see Figure 7). The shutoff achieved through this construction, in conjunction with proper actuation, is: — Teflon (TFE) balance seal, TFE seat - ANSI Class VI — Teflon (TFE) balance seal, Metal seat - ANSI Class IV or V MSS-SP-6 1 — Graphite balance seal, Metal seat - ANSI Class IV or V
0
Gasket Seal: For high temperature applications (above 800 F) or where large thermal transients are anticipated, the body-to-bonnet sealing and trim loading is controlled through the use of high density gaskets. For the very large thermal transient over-the-plug flow applications, Belleville springs are also employed between the bonnet and trim stack. This isolates the trim thermal expansion from the body/bonnet joint gasket, while providing precise loading to the trim gaskets and seals for long cyclic trim life. Construction Materials Materials are selected based upon a combination of code requirements, the chemical nature of the fluid, CCI’s past experience. and the economics of construction.
Pressurized Seat Plug The pressurized seat plug (see Figures 6A-6C) is a special form of the balanced plug, that is balanced during modulation, but unbalanced when shut off. While the unbalanced and balanced plugs may be applied in either over-the-plug (flow-to-close) or underthe-plug (flow-to-open) configurations, the pressurized seat plug is applied only in a flow-to-close configuration. When the valve is completely shut off, as in Figure 6A, the balance hole is closed by the valve stem. The unbalanced, intentional leakage past the piston rings on the valve plug lets upstream pressure build up on top of the valve plug, creating very high seat loading for superior shutoff with a metal-seated valve. This seat loading is in addition to the actuator loading applied to the seat, and is exemplified by the values shown in Table 1. Figure 6C shows that once the stem is lifted to uncover the balancing hole, the main valve plug can be opened as easily as any other balanced plug configuration. With the superior shutoff (MSS-SP-6 1) provided by this plug configuration in high pressure drop applications, the system designer can often eliminate the need for upstream block valves.
Body/Bonnet Closures Two methods are applied generally to provide a leak- free joint between the body and the bonnet. The normal method utilizes a metal seal (see Figure 4A), while special applications use a gasket seal (see Figure 4B). Metal Seal: The bonnet bolting load is transmitted through the bonnet flange directly to the metal seal. The metal seal then transmits its load through the bonnet to hold the quickly removable disk stack and seat ring firmly in place. Leak-free operation is provided by the pressure inside the valve, which self-energizes the metal seal.
Typical construction materials are listed in Table 2. Other materials also may be substituted for the tabulated materials to meet special requirements. Additional Specifications Actuators: The standard CCI actuator is a high performance, double acting, piston type with positioner. CCI actuators are offered with or without manual override and with or without springs. Typical construction materials are listed in Table 3. When necessary for control, we also provide manual, electro-mechanical or electro-hydraulic actuators. Typical Valve/Actuator Configurations: Typical end connection sizes, dimensions and weights are given in Table 4 for globe style valves and Table 5 for angle valves. Information given assumes use of the high performance CCI pneumatic actuator.

CCI Services
Today’s plants are running longer, at higher outputs, and under more sophisticated plant automation systems than ever before. And it all radically increases the performance demand on your control valves. What you need is a resource. Someone who knows these valves and their applications from the inside out. Someone who knows the answer when control valve performance starts slip-ping. Someone like the control valve experts at CCI. Today, maintaining peak performance of critical system components like control valves means more to you. It always has to us. n
Parts
When your valves need a spare part, use ones you know will work — parts from the original manufacturer. Many CCI DRAG® and CCI-Bailey valves are completely custom-designed and built. We have the original drawings, specifications, and equipment to make the right replacement part for your valve. Not a copy, but the exact part to fit your needs. Made from the right materials, to the right dimensional specs, by qualified machinists, with Nstamp qualification, when needed. And all our spares meet the original industry standards for which the valves were designed: API, ANSI or ASME n
Field Service
When you need an expert at your elbow, our fully trained and experienced Field Service Technicians are the right answer. Whether it’s a routine maintenance check or an emergency repair, our team has the experience, the tools and access to all information about the valves we built for you to insure that your valves will go on performing the way you expect. When your conditions demand it, our people can completely rebuild a control valve in line at your site and re-calibrate it before returning it to service. They’ll even help sort our your spares inventory.

Rebuilds Our factory-trained specialists handle complete rebuild procedures including full disassembly and cleaning, weld-ing, overlay and modification or fabrication of needed parts, part matching for tight sealing, reassembly, leak testing, paint-ing and return shipment — and this applies to the smallest cage trim valve and the biggest DRAG® severe service valve. We even have a unique exchange program to shorten your downtime for rebuilt type VBJ actuators typically found on CCIBailey valves. Call us today for more information.
