Subsea axial choke valve

The newest topside technology is also available for subsea applications now. Due to the high capacity and large sizes, these valves are ideal for high flow wells and the axial flow design eliminates the possibility for cage collapse.

Facts

Subsea qualified

Successful qualification of components, compliance to PR2 testing, 500.000 stroke endurance testing without stem seal leakage, hyperbaric testing.

Axial flow

Streamlined flow path through full-port expanded body avoids turbulence and prevents erosion and vibration.

Unique TVM®

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

Severe service

Suitable for unclean process medium. As a standard supplied including Tungsten Carbide trim for ultimate reliability.

Fast control

Fast stroking and accurate control is possible due to the pressure balanced piston rod. Especially suitable for anti-surge applications.

High capacity

The inherent capacity of the axial valve is very high compared to conventional control valves and enables the selection of a smaller valve size.

Actuator flexibility

The valve is suitable for a variety of linear subsea actuators. Designed for automatic operation with hydraulic or electric subsea actuators.
