Roto-Disc®’s New Drive System & High-Strength Shafts Eliminate Taper Pin Shearing

Erlanger, KY – For Immediate Release:  All Roto-Disc®, Inc. shut-off valves are now standard with a redesigned drive system that eliminates taper/shear pins both inside and outside the valve. This system connects the dome to the actuator through square holes in the dome and square ends on the mating shafts. New high-yield stainless and carbon steels are also used, and removal and re-insertion of the shafts is greatly simplified. This new, robust design allows additional torque to be applied to power the valve through hard or sticky material without concern for taper pin shearing. 

The direct-drive feature, offered on the company’s Roto-Clean® sanitary valve since 2005, is now available on the Roto-Disc®, Roto-Disc II, Roto-Flate® and Roto-Vert® valves as well. This means all valves share the quick shaft removal and reinsertion feature of the Roto-Clean. The design works well with most actuator types because most actuators have female drive shafts. Roto-Disc, Inc., offers conversion packages to this new design for its current installed base.

These square shaft and dome holes are machined to exacting tolerances and hand-fitted to provide a tight slip-fit that won’t allow the actuator and dome to become decoupled.
