Patent ID: 8070127

Claim:
A manual override apparatus for use with a valve, comprising: a manual operator having a first coupling on a first side and a second coupling on a second side opposite the first side; a first drive member having external threads and coupled to a housing of an actuator, wherein the first drive member includes a first end to removably receive the first coupling of the manual operator, a second end to selectively engage an actuation member of the actuator, and a bore therethrough along a longitudinal axis of the first drive member; and a second drive member disposed in the bore to be rotatably coupled to the first drive member, wherein the second drive member has a first end threadably coupled to an actuator stem of the actuation member and a second end to removably receive the second coupling of the manual operator, wherein rotation of the first drive member in a first rotational direction via the manual operator moves the actuation member of the actuator in a first linear direction and rotation of the second drive member relative to the first drive member in the first rotational direction via the manual operator causes the actuation member to move in a second linear direction opposite the first linear direction.
