DESIGNED WITH A HEART OF STAINLESS STEEL

Stainless steel yoke

The heart of any scotch yoke actuator is the yoke. S series actuators use

17-4PH stainless for this critical area as standard.

The yoke is the mechanism used to convert linear force to torque.

This area is most often where the life of the actuator is controlled.

Principles of construction

Using high quality materials of construction and modern rugged design

concepts provides the standard for high quality, low cost valve actuation.

The S actuator housings are all machined from 316 stainless steel castings.

This produces a rugged, low cost product through reduced machining time

and by eliminating wasteful excess material.

Any components that rotate or slide during operation, such as the high

strength stainless steel output shaft, stainless steel piston rod, stainless steel

thrust pin or the stainless steel piston, are all supported by replaceable friction

reducing bearings.
