VariStroke I

The new industry standard electro-hydraulic linear actuator used in the most demanding environments providing superb accuracy and resolution for stable, reliable and safe operation of steam turbine control valves or valve racks. Used on mechanical-drive or generator-drive steam turbines, the robust design with 50 lbf chip shear force, and self-cleaning port design uses a low-pressure hydraulic oil source (typically turbine lube oil) for output shaft force. The V45TD-2010-MU is an integrated double acting universal mount 200mm bore/100mm linear stroke fail-extend male-thread shaft actuator for steam and hydro turbines.
