ABSTRACT:
A lockout module is adapted to be mounted between an actuator-to-valve mounting kit and a valve actuator, and is operable to lock the valve in either an opened position or a closed position. In a preferred embodiment, the lockout module comprises a housing, a spindle, a lockout pin, and a lockout tab. The lockout pin is inserted in the housing for selective engagement and blocking of the spindle or for releasing the spindle. A padlock is locked through a lockout wheel on the lockout pin and the lockout tab, the lockout tab engaging a groove within an appendage of the housing to prevent pin and valve movement. In an alternative embodiment, the lockout module comprises a housing, a spindle, a pair of lockout pins, and a pair of pull pins. The lockout pins are inserted in the housing for selective engagement and blocking of the spindle or for releasing the spindle. The pull pins are inserted through the housing and the lockout pins, and padlocks are locked through bores in the ends of the pull pins to secure them, the lockout pins, the spindle and hence the valve.
