    Abstract: A valve operator for closing a globe valve against heavy back pressure has two different types of drives. The two drives are used in succession. A first type of drive is used for moving the valve stem lengthwise to move the globe valve between open position and an almost-closed position. A second type of drive is used to move the valve between the almost-closed and fully closed positions. The first type of drive includes a rotatable nut threaded on the valve stem, and drive means for rotating the nut. The second type of drive involves a roll-ramp assembly which, when driven rotationally, exerts an axial thrust against the nut and moves the nut without rotation thereof in the axial direction of the valve stem, moving the stem with it. The roll-ramp assembly includes a cam sector driven angularly through a part of a revolution to force a set of rollers up inclined ramps to increase the axial spacing between the rotatable cam sector and a fixed cam plate. While a typical use for the valve operator is for globe valves, the operator is equally applicable to gate valves, sluice valves, or other types of applications requiring linear movement and forces of great magnitude.

    Abstract: A valve operator incorporates an explosive actuator which includes an elongated twisted steel tube, for emergency use in, for example, closing a valve quickly. When the emergency arises, the explosive charge in the twist actuator is fired and the gases generated by the explosion cause the twisted steel tube to untwist. One end of the twist actuator is fixed. The other end, which is free to rotate, is connected to the valve stem. Rotation of the free end of the twist actuator moves the valve quickly to the desired emergency position, which may be either the closed or open position. Two forms are disclosed. In one, the twisted-tube actuator is a series component of the normal gear drive. In the other, the actuator is coupled or decoupled by a clutch mechanism.
