Duxvalves

We are an organisation specialized in Valve & Actuator engineering. Established in Almelo (The Netherlands), we produce high-quality products in accordance with well-known international standards.

Our focus is on quality, flexibility and reliability. Working in close harmony with our clients to gain the best solution for each typical application.

Product performance feedback is much appreciated by our clients, as this allows for regular improvement. Focussing on the most severe applications, we are capable of improving your system. Using our product for both new projects and modifications on current installations will prove to be very interesting when looking at the total costs of ownership.

The Team

Our team consists of experienced professionals who have worked with these kinds of products and applications for many years. They have built up a tremendous amount of experience based on feedback from the field. The added value to our customers is not only limited to superior products and low life-cycle costs but is also related to in-depth knowledge of our customers' processes and operating practices.

Furthermore, our familiarity with international standards and design practices, product application expertise and our know-how on application related disciplines such as metallurgy and control systems, contributes to customer demands. Complementary to this is our After Sales and Services capabilities, which enable us to provide an excellent Worldwide Service.


General Applications

Duxvalves manufactures choke (control) valves and control valves used for severe conditions. These conditions most likely occur in the Oil & Gas exploration and storage environment, which incidentally can also be found in the petro-chemical or other industries.

In general our valves are used on applications where there are one or more of the following conditions:
  • - High pressure (drops)
  • - Abrasive (erosive) fluids
  • - Corrosive fluids
  • - Cavitation/flashing
  • - High seat tightness requirement
The importance of implementing a Duxvalves on specific applications:
  • - Our unique design enables us to extend the meantime-between-failure (MTBF) substantially, resulting in low maintenance and life-cycle costs
  • - The in-depth knowledge of our customers’ process and operating practices
  • - Our familiarity with International standards and design practices, product application expertise and our know-how on application related disciplines, such as metallurgy and control systems, which contribute to customer demands
  • - Our After Sales and Service capabilities, enables us to provide worldwide service

Valve principles

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.
