Main product features
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.
Special features
- Custom-designed valve trim for each unique control application.
- Suitable for applications that require a high turndown.
