integrated brushless servo motor, onboard servo drive, industrial Ethernet communications, valve seating algorithm, and field tested, industry proven inverted roller screw design.
One of the proven Curtiss-Wright product brands is the Tritex ® series, consisting of fully integrated linear and rotary actuators with the performance and reliability for upstream oil & gas applications across North America, including the Permian Basin, Eagle Ford Shales, and other prominent industrial regions in the U. S.
For more than 30 years, the company has successfully fielded more than 10,000 Tritex units in valve control applications. To expand on its capabilities, Curtiss-Wright is launching the Tritex EX, providing an even more robust solution for operators and end users in upstream oil & gas. It joins proven Tritex offerings including the TTX, TDX, and T2X AC linear actuators as well as the R2M / G AC and RDM / G DC rotary actuators.
“ Our customers and partners are loyal to us as our designs are extremely reliable and reduce their risk," said Holmgard.“ With this proven, high-performance technology for valve control, we have created another resilient product that can operate maintenance-free for many years.”
Proven Roller Screw Design and the New Tritex EX
The inverted roller screw design is a core technology of Curtiss-Wright, electric actuation products going back to the earliest actuation systems. While the first roller screw product was initially designed for packaging equipment and general industrial applications with capabilities of 24 / 7 operation, the Curtiss-Wright engineering team has applied that same technology across many actuation applications.
“ The inverted roller screw is similar to a ball screw but has incredibly durability and typically lasts 15 times longer in typical industrial applications,” explained Holmgard.“ With those design attributes, we first optimized it for a linear control valve, and it worked amazingly.”
Due to its reliability and extremely robust design, only minor modifications
