Rotary Vane Actuator |
|
| |
Best Suited Applications |
|
| |
Only
One
Moving Part
Engineered for a 50 year design life with routine maintenance.
|
-
Quarter-turn valve applications on natural gas pipelines, utilizing
gas over oil power pressure for the actuator.
-
Emergency shutdown.
-
Line break protection.
-
Valve control on product pipelines where the actuator is powered
hydraulically or by nitrogen storage vessels.
-
The
actuator's concentric shape and balance is perfect for high vibration
applications.
-
Compact design is ideal for platform applications and subsea
applications.
-
High pressure construction and compact design allows for subsea
applications to depths of 750 meters without pressure compensation
devices.
-
High speed applications with stroking times as fast as 250
milliseconds.

Features
|
|
|
 |
-
Only one moving part allows for a 50 year design life with minimal
maintenance.
-
Double vane design will not produce any side loading forces on the
valve stem or actuator bearings.
-
Balanced and constant torque is applied directly to the valve stem,
without any internal power loss, throughout the complete stroke.
-
The
most compact and efficient actuator design available.
