Rotary Valve Actuators

Cowan's Rotary Valve Actuators Lineup


A rotary valve actuator is a mechanical device that converts electric, hydraulic, or pneumatic energy into rotary motion. Revolving on a circular path, this type of actuator is typically defined in degrees. It can be set to finite or infinite, depending on what the customer needs.

Cowan offers a variety of rotary valve actuators that can be customized to fit the customer’s requirements for a variety or markets and applications. We also offer valve mounting kits that can be designed for any rotary valve.
