Specifications and indicators of PTFE ball valve seat and valve stem gasket
specifications and indicators of PTFE ball valve seat and valve stem sealing gasket:
features: they all have excellent properties such as wear resistance, high strength and recyclability. The PTFE ball valve seat and valve stem sealing gasket are made of suspension polymerized PTFE resin molding. Polytetrafluoroethylene and other plastics are gradually becoming the main theme of the industry. Compared with other plastics, polytetrafluoroethylene has excellent chemical corrosion resistance and temperature resistance. Purpose: valve seat and stem sealing
PTFE,ballvalve seat is manufctured by molding method with PTFE granular resin.
PTFE, Compared with other plastics, has a superior properties against chemicals and temperature.
