The VariStroke-II actuator is part of a product family with many different models available for purchase

depending on the force, stroke, and redundancy needs. This actuator is available with standard bore

diameters and standard stroke ranges. The VariStroke-II’s unique “variable stroke” capability also allows

users to customize/set the actuator’s exact stroke length in the field to meet their requirement.

The VariStroke-II is factory and/or field configurable via a computer-based service tool. The actuator’s

PCI Service Tool uses a simple, user-friendly format to allow users to easily configure, calibrate, and

adjust all internal functions and response settings. The VariStroke-II also includes a 4–20 mA output

channel to indicate output shaft position, and unit alarm and shutdown relay outputs for use as unit

health and status indications.

The total installed cost for the VariStroke-II is low because it is a fully integrated actuator that has been

completely assembled and tested at the factory. This greatly reduces OEM and end-user fabrication time,

testing time, and site assembly time.
