<p>Manual valve operators having a locking device are described. An example manual operator includes a lever rotatably coupled to a locking plate and has a handle 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 member is removably coupled to the handle. The handle has an aperture to receive at least a portion of the lockout member. The lockout member engages a portion of the lever to prevent the handle from pivoting between 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.</p> |
