ABSTRACT:
A lockout module comprises a housing having at least one lockout bore therethrough, a spindle disposed in the housing and having a pair of lockout cross bores therethrough, and a lockout pin selectively insertable through the housing lockout bore and one of the spindle lockout cross bores for blocking rotation of the spindle relative to the housing in first or second position. Slotted bolt holes spaced through and around the periphery of the housing are utilized to secure the housing to a mounting bracket and valve actuator. The slotted holes allow the housing sufficient rotational travel such that the housing lockout bore can be rotatably aligned with a selected spindle lockout cross bore before securing the bolts, thereby compensating for under or over travel of a valve in the open or closed position.
