Factrory Engineered Upgrade Request 


Shafer® actuators have a design life span of over 50 years.  Upgrade your current actuator for today's applications. 

Shafer® offers modification packages to retrofit your installed base of Rotary Vane and Linear Actuators. These upgrade kits equip your actuators with the latest control technology offered by Shafer®. The standard controls are designed to reduce, and in most cases eliminate, external adjustments required for proper control action. Control components are manufactured from corrosion resistant materials for longevity in service. Factory engineered upgrades insure that your equipment documentation remains intact and that component selection and application are correct for your Shafer® equipment.
