Fast response actuation

Exlar Corp.’s Tritex II linear actuator handles control valve and damper process control applications in hazardous areas that require a fast response to the smallest command signal changes, even when friction is present.


Exlar Corp.’s Tritex II linear actuator handles control valve and damper process control applications in hazardous areas that require a fast response to the smallest command signal changes, even when friction is present.

Combining a brushless motor, a specially designed roller screw mechanism for converting electric motor power into linear motion and a built-in position controller, the linear actuator delivers forces up to 3,685 lb., strokes up to 18 in. and speeds up to 33 in. per second.

The Tritex II also comes in a rotary configuration for ball and butterfly valves, providing continuous torque ratings for modulating-duty applications of up to 4,000 lb./ft.-in. The actuator directly couples to the valve’s shaft, eliminating all linear-to-rotary linkages and significantly reduces backlash.

It mounts on any valve from any manufacturer and the Chanhassen, Minn.-based manufacturer of motion control products says both configurations have a -20 to 65 degree C range.
