Manual valve operators (102) having a locking device are described. An example manual opera-tor includes a lever (126) rotatably coupled to a locking plate (130) and has a handle (128) that pivots between a first position to prevent rotation of the lever relative to the locking plate and a second position to enable rotation of the lever relative to the locking plate. A lockout mem-ber is removably coupled to the handle. The handle has an aperture (162) to receive at least a portion of the lock-out member. The lockout member engages a portion (154) of the lever to prevent the handle from pivoting be-tween the first and second positions to prevent rotation of the lever relative to the locking plate when the lockout member is coupled to the handle. |
