Products

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

DUXDRIVE

Next to our wide range of choke and control valves we also manufacture pneumatic and hydraulic actuators.

Testing

Our objective is to deliver a high quality product. To demonstrate the capability of our products each item is individually tested. Our Test Facility enables us to do the following tests in house

Short delivery

Due to the fact that our products are used in critical processes, delivery times are essential. Therefore our supply chain is set up in such a way that we are able to guarantee

Research & Development

R&D has a central role in our organisation, as we are supplying tailor-made solutions for each typical application. The R&D is carried out by our highly qualified and experienced Engineering Team

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,

Repairable internals

Given the spring-loaded design and the solid Tungsten Carbide discs the Duxvalve internals can be repaired.

Service

Duxvalves is a service minded organisation where we focus on solving your problem. Our products are regularly used in critical processes and therefore excellent and reliable service is essential.

Focus is on quality, flexibility and reliability

Testing

Our objective is to deliver a high quality product. To demonstrate the capability of our products each item is individually tested. Our Test Facility enables us to do the following tests in house:

Hydrostatic body & seat testing upto 1.800 Barg (+26.000 Psi)
Gas (Nitrogen) body & seat testing upto 800 Barg (+11.500 Psi)

The Test Facility is directly linked to a computer, monitoring the data and generating a Digital Test Report.

For the gas test the valve is placed in a water basin and with a remote operated camera the valve can be monitored from safe place outside the bunker.

To prove the correct functionality of the product we also perform a:

Functional test

Furthermore, our testing facilities include:

Cv and Fl test loop

In this test loop we comprehensively test, among others, the valve flow co-efficiency, and the valve liquid pressure recovery factor.

The layout of our test loop meets the ANSI/ISA-75.02-1996 requirements.
