When selecting an electric actuator for industrial valves, an understanding of the valve torque requirements, both at start of travel, and end of travel, is critical for proper operation and optimal service life. Additionally, the ability to accurately set, or limit, disk travel is required.
Many of today's industrial electric valve actuators provide easy setting or programming of travel and torque sensing.
This short video provides a brief visual understanding of the reasons why valve torque and travel limits are important.
