Abstract:
1. A system adapted for controlling a valve, the system comprising: a valve; a pneumatic actuator having a shaft extending through the actuator, the shaft having a first end and a second end, the first end being coupled to the valve for controlling the valve; a limit switch bracket fixedly mounted to the actuator; a limit switch mounted on the limit switch bracket and coupled to the second end of the shaft of the actuator; and a lock-out bracket comprising a substantially flat base plate and a substantially flat lock-out tab extending substantially perpendicularly from the base plate, the base plate defining a square hole through which the second end of the shaft extends from the actuator to, and is coupled to, the limit switch; the lock-out tab defining a first hole for alignment with a corresponding second hole defined on the limit switch bracket adapted for facilitating the insertion of a shackle of a lock through the first hole and the second hole to secure the lock-out bracket relative to the actuator and adapted to prevent movement of the first end of the shaft adapted for controlling the valve.
