Tetrafluoroethylene (PTFE) seats, stem seal:
Kun Yongjia County of valve Parts Factory Professional production: Carbon steel welded flange; metal spiral wound gasket; PTFE gasket; graphite composite pad; rubber seals; stainless steel welded flange; octagonal pad; asbestos gasket
Polytetrafluoroethylene (PTFE) valve seat And stem gasket is optional suspension polymerization PTFE resin molding material. PTFE compared with other plastics resistant to chemical corrosion and excellent temperature characteristics by adding fillers in hardness can Greatly improve.
Fillers: glass fiber, molybdenum disulfide, graphite, polyimide, carbon fibers, silica, polyphenylene sulfide, and other specifications DE valve seat, and the company already has a full set DN15-DN800 ball valve seat mold.
Some products commonly used specifications:
DN300 above specifications, please call our request.
Note: Our company can make by modifying PTFE seat at -196 ° - + 300 degrees or less normal use.
GM materials, various rods, tubes, plates film, tape, rope, packing, gaskets, and graphite, molybdenum disulfide, aluminum oxide, glass fiber, carbon fiber as a filler to increase pure PTFE mechanical properties.
