Section 1: Overview
All Bettis RGS Q-Series actuators are designed and built with the intent that they will last
forever. Numerous design features reduce friction for enhanced operation, less wear and
longer life. Other features result in there being fewer dynamic seals - a seal that does not
exist cannot fail. Also, we employ readily available off the shelf seals that cost far less
than other’s proprietary parts, and we do so in a design that allows seal replacement
while the actuator remains in line (see Section 6, Maintenance Section).
