Notes: 1. Operating speed is nominal at rated torques. Final operating speed may vary depending on actual service.
2. Actuators with 12VDC motors will have an operating speed of approximately 40% longer (slower) than that shown.
3. CF – Consult Factory
4. Bettis does not recommend the use of any actuator for any modulating application with an operating speed of 10 seconds or less.
