Forged Steel 3pc ball valve 800lb F316L

There are two design forms of the three -piece forging steel Ball Valve. One is a two -piece structure, which is connected to the thread of the part and seal it with PTFE pads; The valve seat is different from the material of the pads/fillers. It adapts to different working temperature and medium. Forging steel ball valves are mainly used for oil, long -range pipeline transportation of natural gas and urban gas pipeline system. Due to the unique characteristics of the long -pass pipeline valve, it fully considers its ability to withstand pipeline stress, as well as security, weather resistance, long -term reliability, etc.
