Servovalve Scotch Yoke actuators designed for max output torque up to 500.000 Nm are available with canted ( RCPM ) or symmetric ( RSPM ) yoke to better adapt to valve’s torque requirement minimizing cylinder and spring dimensions and cost.
Both execution are heavy duty design with central housing and other external parts in carbon steel avoiding use of aluminum or cast iron.
Central housing is equipped with transversal guide bar to ensure smooth and precise movement even in the most critical control valve application.
Modular design allow a wide range of combination of spring cartridges and cylinder so to optimize sizing on valve torques.
As option are available manual emergency override as handwheel, handwheel with side gear and hydraulic handpump.
