Plug Valves

Plug valves have a simple structure, rapid switching, small fluid resistance, in accidents and other emergencies, can quickly connect or cut off the pipeline. Compared with gate valves and globe valves, they are more flexible in operation and more rapid in switching. Plug valve is a plug with a hole as the opening and closing parts, plug body with the valve stem rotation, to realize the opening and closing action.

Plug valves are simple in structure, rapid in switching and small in fluid resistance, and can be quickly connected or cut off the pipeline in case of accidents and other emergencies. Compared with gate valves and globe valves, they are more flexible in operation and more rapid in switching. Plug valve is a plug with through hole as the opening and closing parts, plug body with the valve stem rotation, to realize the opening and closing action. Plug valve plug body for more conical and valve body conical hole surface with the composition of the sealing vice. My company produces two kinds of plug valves, one for the semi-lining type, is the plug package fluorine plastic, the valve body sealing ring is surfacing alloy steel or hard alloy; the other is a full lining type, the valve body and the plug is completely covered with fluorine plastic. Because of the fluorine plastic coating of the valve, has a strong anti-corrosion, can be applied to various concentrations of hydrochloric acid, nitric acid, aqua regia, alkali solutions and other media. In the chemical, pharmaceutical, printing and dyeing, petroleum and other industries have a wide range of applications.
