A solenoid operated valve system for petroleum production wells including a solenoid operated valve securable in a well bore connected to the lower end of a tubing string extending to the surface. The valve of the system includes an outer housing, an inner wall defining a flow passageway therethrough and an annular cavity therebetween for receiving the solenoid coil and associated electrical components. The spaces in the annular cavity surrounding the solenoid coil and components is filled with an electrically insulative filler material to protect the el...
A method of manufacturing an electrically operated solenoid actuated safety valve comprising: providing an elongate tubular safety valve housing assembly including an outer housing, an inner wall defining a tubular passageway for allowing fluid flow through the valve assembly, an annular space therebetween and an elongate bore extending axially from the top of the annular space to the top of the outer housing; mounting a tubular magnetic armature for axial movement within the tubular passageway through the valve assembly; spring biasing said tubular arma...
