Abstract
A valve assembly including a valve actuator and valve is provided. The valve actuator includes a mechanical hold arrangement configured to allow manually setting the position of the valve actuator and its drive gear and to oppose any loading provided by a return spring biasing the valve actuator and drive gear out of the set position. The valve actuator includes a spring lever and a recess in which the spring lever is secured to lock the position of the valve actuator and drive gear when the electric motor of the valve actuator is de-energized. The valve actuator can be reconfigured to provide mechanical holding for manually setting the orientation of the drive gear when a return spring load is provided in either a clockwise or counter-clockwise direction.
