Axial control valve

Selecting Mokveld axial control valves with proven reliable performance will help to reduce costly maintenance and lost production time; a choice that will ensure the safe and reliable operation of your plant.

Facts

Axial flow

Streamlined flow path through the full-port expanded body avoids turbulence and prevents erosion and vibration. Process downtime and maintenance costs are reduced.

Unique TVM®

Total Velocity Management® concept: intelligent valve design that carefully manages fluid velocity in all areas of the valve.

High capacity

The inherent capacity of the axial valve is very high compared to the conventional globe control valve and enables selection of smaller valve size. Alternatively the higher capacity can be used to minimize pressure loss or to provide for special control features.

Accurate control

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

High turndown

High inherent capacity and accurate control features make the valve suitable for applications that require high turndown providing one-valve solution for the full process envelope.

Silent

Streamlined flow path avoids turbulence and therefore energy conversion in the valve body itself. Pressure drop is taken over trim only. Dynamic body noise is minimized.

Compact

The one-piece valve body provides 20% - 70% weight reduction compared to globe valves. This feature is even more attractive combined with spring-opposed actuators.
