ABSTRACT:
A device for actuating a valve including a body having a slot therein. A pin is positioned within the slot, and the pin is attachable to a valve stem of a valve, whereby when the valve stem is attached to the pin and the pin is moved within the slot, the valve stem moves therewith and actuates the valve. There is also a rotary actuator assembly including a rotary actuator, a body having a chamber therein attached to the actuator, and a valve associated therewith. A slot is provided in part of the chamber, and a pin extends through the slot for guiding movement of the valve stem of the valve when the valve stem is attached to the pin and the rotary actuator is actuated. The slot may be configured as a helical slot. A piston may be provided between the valve stem and the pin. The configuration of the slot may be varied for changing the length of movement of the pin, so as to change the length of movement of a valve stem attached thereto.
