Abstract:
1. An actuator and valve arrangement comprising: an actuator and valve portion at least one housing including the valve portion having a first port for receiving a fluid and a second port for delivering a fluid a valve seat disposed between the first and second port, a valve member operable with the valve seat for controlling fluid flow between the inlet and outlet ports; a valve stem operably connected to the valve member, having a longitudinal axis, a first end, second end and second portion, the valve member is attached at the first end and the second location is located between the valve member and the second end; a first component, operably connected to the second portion of the valve stem, for transmitting an operating force to the valve stem to force movement of the valve stem in a first direction; a second component, operably connected to the second location of the valve stem, for transmitting an operating force to the valve stem to force movement of the valve stem in a second direction; an actuator portion within the housing including a rotary actuator and at least one gear that is rotatable with the actuator; the at least one gear having first and second features for transmitting force from the actuator; a bias spring system including at least one spring providing a force applied to at least one of the first or second components and at least one of the first or second gear features that will urge movement the valve stem and valve member in relation to the valve seat; wherein during an unrestricted valve movement condition, where valve movement is not restricted, the first feature of the gear contacts the first component, operably connected to the second portion of the valve stem, for forcing the valve member in a first direction, either towards or away from the valve seat, when the gear is rotated in a first direction by the actuator and; during a restricted valve movement condition, where valve movement is restricted, the second feature of the gear contacts the second component, operably connected to the second portion on the valve stem, for forcing the valve member in a second direction, either towards or away from the valve seat, when the gear is rotated in a second direction by the actuator.
