Valve principles
3D animation: The principle of a choke valve
Duxvalves produces a wide range of choke and control valves. These valves can be equipped with several types of valve principles (internals) depending on the specific application and considering the process conditions.
The valve principles are listed below:
| Principle | Trim type | Application | |
| 1. | Basic Disc | BD | Simple rigid design |
| 2. | Pico Disc | PD | Wide range for large range ability |
| 3. | Large Cv disc | LC | “Full bore” design with Cv value up to 650 |
| 4. | Wide range Low noise disc | WL | Large range ability icw low noise production |
| 5. | Low Noise disc | LN | Low noise design icw strainer |
| 6. | Filter Disc | FD | Filter to avoid clogging up the system |
| 7. | Cage Disc | CD | 2 stage flow control |
| 8. | Diamond Disc | DD | For extreme heavy duty applications |
| 9. | Dual Orifice | DO | High range ability and dual applications |
| 10. | Micro Disc | MD | Micro design for very small Cv values |
These internals can be executed in both angle and inline body styles depending on the piping configuration.
The product range is:
Body size: ½ – 6”
Pressure rating: 150 – 2.500 lbs ANSI
2.000 – 15.000 lbs API
Cv value: upto 650
Material combinations are based on customer requirements and can easily be adapted. At the download section you will find information with regard to the recommended or most common material combinations.
Detailed information on sizes, face to face dimension, weight and Cv value, can also be found at the download section.
