VRA

Rotex VRA Series Vane Actuator

Compact, constant-torque vane actuator with adjustable vane alignment, low-friction bearing system and quad-seal arrangement for heavy-duty valve service.

Industries served

Oil and Gas ,Midstream

7° adjustment is available for vane alignment.
One-piece drive shaft and vane.
Unique bearing levelling system “ULTRAVEL” is designed for negligible friction.
Adjustable vane level avoids completely the friction and wear associated with misalignment.
Highest torque output from the same family of actuators, as stated in the catalogue.
Unique quad-seal arrangement provides sealing against O-rings with low friction.
Angular contact bearings support the heavy weight of the vane and adjustable bearings keep the vane centred between the two covers.
Smooth working and reduced sealing-surface erosion increase seal life.
VRA can be configured for gas-over-oil / gas-operated applications with compact, constant-torque operation and zero-jamming characteristics.
GOV application can use an integrated hydraulic block with no external tubing between internal hydraulic components.
Slurry pipeline application supports common HPU, 0.5 micron filtration, multiple VRA actuators and redundant HPU configurations.
