Main technical features:

Axial flow:

Streamlined flow path through full-port expanded body avoids turbulence and prevents vibration and erosion of body and trim parts. Its reliability reduces the total cost of ownership and unplanned process downtime.

Availability:

The Total Velocity Management® concept is an intelligent valve design that carefully manages fluid velocity in all areas of the valve, minimizing erosion in body and trim. This significantly increases production availability. 

Accurate Control:

Accurate control is possible (also with minimum opening) because of the fully pressure-balanced trim. Small, spring-opposed actuators can also be selected for large valve sizes.

  High turndown:

High capacity and accurate control features make the valve appropriate for both start-up and well depletion production scenarios. One-valve solution for full process envelope. Large hole trims for dirty well clean-up service and high capacity trims for minimized pressure loss at well depletion stage. 

Compact:

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

Process Safety:

Sometimes, a choke is considered as a safety device to prevent overload of the relief system. In this axial choke the Tungsten Carbide cage is inherently protected against direct impacts by foreign objects.
