Valve actuator with lock mechanism

摘要

A valve actuator (10) with manual lock is provided. The valve actuator (10) with manual lock includes a locking button arrangement (12) that is operably coupled to a shaft (78) extending along an axis of rotation of a drive train (72). The locking button arrangement (12) is selectively engageable with a housing (30) of the valve actuator (10) to lock the drive train (72) in a selected orientation.
