Patent ID: 8061683

Claim:
A manual operator for use with a valve, comprising: a lever rotatably coupled to a locking plate and having 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, the handle having an aperture disposed between a pivot axis of the handle and a biasing element, wherein the biasing element is disposed between the handle and the lever to bias the handle toward the first position; a first tab protruding from the lever and toward the aperture of the handle, the first tab being substantially aligned with the aperture to expose the aperture when the handle is in the first position and to obstruct the aperture when the handle is in the second position; and a lockout member removably coupled to the handle the aperture of the handle to receive at least a portion of the lockout member such that the lockout member is to engage the first tab of the lever to prevent the handle from pivoting relative to the lever 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 aperture of the handle.
