About Us


In 1996, K-TORK International, Inc. embarked on a mission to design and produce the World's Finest High Performance Valve Actuator.

It was important for K-TORK to incorporate some of the same features found in the imported design to facilitate retrofit field installations:

  • Identical mounting bolt circle dimensions so that K-TORK actuators will mount onto EXISTING mounting brackets without any modification to the bracket.
  • Identical output drive shaft dimensions so that K-TORK actuators will utilize EXISTING couplings without any modifications to the coupling.
  • Same torque outputs for each similar Model.

From there, we improved K-TORK actuators with the following patented features:

  • Integral NAMUR solenoid mounting pad.
  • Integral VDI / VDE 3485 NAMUR accessory top works mounting pad for positioner and limit switch controls.
  • 150 PSI maximum working pressure rating, 220 PSI maximum over-pressure rating per
    AWWA C-540, Power Actuating Devices.
  • 300° F. maximum temperature rating with K-SEAL modifications.
  • High-Tensile alloy steel – electroless nickel-plated vane and output shaft.  Kinetrol uses ductile iron on similar models.

In short, K-TORK actuators were designed for long-life and the precise control of ¼-turn valves.  With only one moving part, the simplistic design provides years of service in demanding, high-cycle, fast operation and critical modulating applications.

To reinforce your confidence in K-TORK, we offer a standard THREE YEAR / 2 MILLION STROKE Performance Warranty.  This is more than a “Materials and Workmanship” guarantee as K-TORK will repair or replace your actuator AT NO COST if it does not perform to your expectations.
