About Us

Founded June 1998 by Ed Holtgraver and Magnus Palmstierna in Tomball, TX

Early in his career, the founder of QTRCO, Ed Holtgraver, was responsible for field service of a large valve company. He saw customers lose large amounts of money, time and production hours from misapplied products, and products that would have worked better if attention to detail had been applied during the design phase.

When founding QTRCO, Ed’s intent was to design and build actuators that simply did not encounter field service issues. From a very rugged mechanical design to elimination of normal failure modes—sliding parts, side load forces and numerous seals—the QTRCO actuators have evolved into exactly what Ed had in mind those many years ago. 

Based around a reduced friction actuator concept patented by Ed Holtgraver.

No quibble warranty, 3 years operation and unlimited cycles

A number of features that differentiate the actuator from competition such as:
  • Physical partial stroke XRCISER
  • Stainless or Amalga barrels
  • Very high operating speeds
  • Simple, safe maintenance (captured springs)
  • Balanced, fully scalable design
  • More new designs in pipeline
