초록

A method of operating a valve can include installing an electrical actuator in a flow passage extending longitudinally through the valve, and operating a closure assembly in response to electrical power being supplied to the electrical actuator. An outer safety valve can include a closure assembly which selectively permits and prevents flow through a longitudinal flow passage, and at least one electrical connector which electrically connects to an insert safety valve positioned in the flow passage. A method of operating an outer safety valve in a subterr...
