The output shaft is supported at the top and bottom with bronze bearings that absorb side thrust and ensure smooth, efficient throttling control. Diaphragm actuators provide on-off or modulating control with either spring-to-open or spring-to-close operation. All diaphragm actuators feature external position indication and are available with safety lockout devices. Refer to Bulletin 70.00-1 for technical details, and Bulletin 70.00-2 for sizing information. | | |
