Abstract

VALVE ACTUATOR A valve actuator is capable of being mounted on a valve in alignment with a valve stem which can be moved to open and close the valve. The actuator includes a hydraulic cylinder and a piston slidably mounted within the cylinder. A piston rod is joined at a first side of the piston and extends outwardly of the cylinder toward the valve to be joined to the valve stem. A high pressure gas accumulator is mounted on the cylinder and includes a generally spherical shaped pressure wall which is intersected by the cylinder to locate an end of the cylinder within the accumulator to allow communication of the interior of the accumulator with a second side of the piston. Hydraulic oil acting on the first side of the piston opens the valve against high pressure gas within the accumulator and evacuation of the hydraulic oil allows the high pressure gas to act on the second side of the piston to rapidly close the valve.
