Our Next Generation Rotary Top-Drive Actuator has been designed to isolate the hydraulic system from the rotation of the drill stem.  This new design provides mud saving remote control of the Drill Stem Safety Valve (DSSV) and can be operated when the drill stem is still in motion.  The Next Generation Rotary Top-Drive Actuator provides a high torque, compact, rugged actuation solution for top drive manufacturers while eliminating the shortcoming of existing top drive actuators.
