Abstract
An actuating apparatus for operating a valve assembly includes an actuator body that selectively couples to the valve assembly and an actuator stem that has an end that extends into the actuator body. The valve assembly has having a valve body, a valve member in the valve body, a valve stem attached to the valve member, and a profile on an end of the valve stem distal from the valve member. The actuating apparatus also includes an adapter assembly in the actuator body having a threaded end that engages the actuator stem, and a profiled end distal from the threaded end that engages the profile on the valve stem and couples to the valve stem, so that selectively applying axial forces to the adapter assembly moves the valve stem and the valve member.
