Planetary Gear Solutions
While the WedgeRock Planetary Gear may look unconventional, you are not likely to find a more efficient, self-locking gear operator on the market. The sliding action of conventional worm gear valve operators typically lose more than 65% of the input torque to friction resulting in heat and wear; inherent in the self-locking function, conventional worm gear operators are less than 35% efficient.
In contrast, WedgeRock Planetary Gears provide a rolling action with numerous teeth always in contact and self-centering gear carriages that evenly distribute contact stress resulting in higher efficiencies and an extended, more predictable cycle life – typically providing efficiencies greater than 90%.
Manual or motorized applications, WedgeRock has a planetary gear design for every application. From quarter turn to multi-turn, rising stem thrust applications, subsea or topside, WedgeRock can provide a robust, compact and efficient planetary operator for your application.

MODELS
WedgeRock RP (Planetary) & RBP (Bevel/Planetary)
Manual or motorizable operator for quarter, multi-turn, & thrust applications.
The WedgeRock RP allows for modular configurations. If a parallel input vs output is required, only planetary ratios need to be selected. If a perpendicular input vs output is required, or if the RP is being used in a rising stem application, a bevel must be selected. Each frame size can support up to two ratios. When the max ratio of one frame size is exceeded, another RP is sized and mounted in series to add ratio as required.
