Plug valve is a shut-off or plunger-shaped rotary valve. The passage port on the valve plug is connected or separated from the passage port on the valve body by rotating 90 degrees to realize opening or closing. These valves are widely used in oilfield mining, transportation and refining equipment, and are also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas and general industries.
Lined plug valve is the plug valve whose chamber or bore and whose runs or port passages are fully lined with corrosion-resistant material, most preferably polytetrafluoroethylene, such valve having recesses in its runs, near their intersection with the bore, into which lining material distended by heat and pressure may creep, and with the valve body defining an internally rounded concave wall or dome at the bottom of the bore.
Main structural features of PTFE Lined Soft Sealing Plug Valve:
A. The product has reasonable structure,reliable sealing,excelient performance and beautiful appearance
B. Its sealing is realized by the sealing face around the sleeve,It has unique 360 degree metal edge for protection and fixing of the sleeve.
C. There is no cavity in the valve for accumulation of medium.
D. Metal edge provides the function of self-cleaning when the plug is rotated,applicable to the operation condition that is glutions and apto smudge.
E. Its characteristic double-dircction flow makes installaiton and use more convenient.
F. The materials of the parts and sizes of flanges can be reasonabnly configured according the actual operation aondition of the requirements of the customers,so as to meet the various needs of engineering.
