The founder of QTRCO, Ed Holtgraver, was responsible for field service of a large valve company. He saw customers lose vast amounts of time, production hours and ultimately money from misapplied products. Products that would have worked better had greater attention to detail been applied during the design phase.
By founding QTRCO, Ed’s intent was to design and build actuators that simply did not encounter field service issues. With a very rugged mechanical design and the 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.
QTRCO pneumatic actuators: Install it and forget it.
Rack & gear® quarter turn Q series, Flat yoke® quarter turn F series and linear L series actuators.
Used and/or approved by GE, Shell, Akzo, Baker Hughes, Basf, Bayer, DuPont, Exxon, UOP, Invista, LyondellBasel, PPG, Total.
If your regular pneumatic actuator doesn’t last because of extreme conditions QTRCO has the solution and they back this by a 3-year warranty which is independent of the number of cycles.
If you need a closing time as low as 0,1 seconds
If you need high reliability & maximum availability
If your actuator is exposed extreme environmental conditions (corrosive, high- or low temperatures)
If you require superior control capability (low hysteresis and dead band)
If you require a unique solution for partial stroke, manual override & integrated lockout)
