Low shear
Typhoon Valve System

Typhoon® Valve System is a cost efficient way to debottleneck your existing or new build separation and produced water treatment systems without requiring additional equipment. This low shear valve system minimizes droplet breakup and the formation of tight emulsions, improving separation and increasing separation capacity. Based on cyclonic flow technique which outperforms labyrinth or drilled hole cage solutions in regard to shear reduction. Use the Typhoon Valve System to achieve compliance to your corporate goals of sustainability and environmental performance.

Cyclonic axial flow

Emulsification and droplet breaking in petroleum phases are directly coupled to shear forces in throttling valves. Shear forces are a function of the volume involved in energy dissipation in the valve. The Typhoon Valve System significantly reduces shear forces by increasing the volume involved in energy dissipation by means of the axial cyclonic flow pattern through the system.

Cleaner Production

An oil in water reduction of 30% to 80% is achievable for choke applications, dependent on the function.

Improved separation efficiency

The Typhoon Valve System reduces oil in separated water and water in separated oil. There is less need for, or improved performance of process chemicals like emulsion breakers, flocculants and anti-foam.


Erosion resistant materials in the cyclonic flow area reduces erosion to improve operational lifetime, similar to the standard Mokveld choke valves.

Accurate control

Linear inherent characteristics allow optimum control for liquid level systems and flow control processes.


As a result of the low actuation force requirement, small actuators can be used; combined with a compact body design  this minimizes the installation’s footprint.

Process safety

In this cyclonic axial flow system the cage is inherently protected against direct impacts by foreign objects. The design further introduces a secondary method to reduce flow rate if cage collapse does occur
