For more than 60 years, since the expansion of the pipeline industry after World War II, Shafer products have been known as dependable, fast-acting and rugged. 

Including pneumatic and hydraulic rotary vane actuators, rotary piston actuators, linear valve actuators, and line break controls, Shafer products assure human safety, protection of vital equipment and preservation of the environment.

Primarily serving the gas transmission pipeline industry, Shafer gas-over-oil actuators have become recognized as “guardians of the world’s pipelines”.  The compact design of the Shafer actuators make them ideally suited for tight space applications. As with all Emerson actuation, Shafer actuators are backed by Emerson’s rock solid warranty, including a 50-year design life and a 10-year warranty for Shafer rotary vane actuators.
