DAC Worldwide's Oil Field Relief Valve Cutaway (295-709) allows for convenient classroom training in the operation, construction, and maintenance of an industrial relief valve, used for gas service. Through carefully planned sectioning and color-coding, the complete internal configuration of the valve is exposed and showcased. Seal features and hardware locations have been retained, allowing for “hands-on” training in maintenance. These valves, commonly used in oil & gas production applications relating to separators, treaters, and other similar equipment, would be of interest to those involved in oil & gas production training.
