The new Tolomatic ServoChoke SVC electric choke valve actuator meets requirements for a more flexible and reliable high-speed actuator in performance drilling applications such as managed pressure drilling (MPD), set-point control or choke-and-kill. Combining an integrated servo motor, planetary roller screws, industrial-automation-grade components and an all-steel body, the ServoChoke SVC quickly and continuously modulates with extreme accuracy and precision in the harshest of environments.

"Compared to hydraulic cylinders, Tolomatic's ServoChoke is more efficient, accurate and flexible," said Ryan Klemetson, target markets manager, Tolomatic. "Compared to conventional (jack screw) electric choke valve actuators, ServoChoke is more precise, faster and maintenance-free." 

ServoChoke is a globally certified electric choke valve actuator with five individual certifications for the classifications of ATEX, IECEx, and Class I Div. 1 all on a single assembly. This eliminates the need for both North American and European standard choke manifold designs. In addition to its global certifications, ServoChoke can operate in temperature ranges from -40°C to +60°C and is sealed to meet IP67 standards. Optional marine-grade paint treatment adds protection against even the harshest offshore environments.

Designed and tested for 100 percent duty cycle, ServoChoke is available with two speed/thrust choices: 7K (7,000 lbs. thrust) and the 15K (15,000 lbs. thrust) for different operational performance requirements. Both are designed to provide years of maintenance free operation even when run continuously 24-hours a day.
