Plug valves have a conical or cylindrical obturator rotating around the axis perpendicular to the flow direction, hence by matching the body and obturator flow openings releases the flow, otherwise closes the valve. Closure is maintained by compressing the obturator into the body cavity and using a proper lubricant between the rotating faces. Plug valves are recommended for on/off services. Vastas Plug valves are of API monogrammed and comply with API 6D standard. Special products are avaible for high temperature & pressure services.
