Ball Valve

Flanged End Metal To Metal Seat Ball Valve

Flanged End Metal To Metal Seat Ball Valve

The seat material of general purpose ball valve employs generally non-material,such as PTFE.Limited by the seat material ,the general purpose ball valve can not be used in case of high articles,and ash dregs neither. Metal to metal seat design has been employed perfectly for the ball and seat,which has also adopted the advanced hardening technologies,such as ultro-sonic spray coating,nickel base spay welding,surface specially hardening,stellite spay welding,ceramic material with high strength and hardness,and so on.Surface hardness of ball and seat may generally reach more than HRC60, maximun is up to HRC74. And application temperature of the material may be to 540℃,maximun is 980℃.Combining strength of the material gets to be more than 10000 PSI.Besides,the surface materials posses also very good resistance properties of friction and impact. Nipo metal to metal seat ball valves are suitable for use in most hard working conditions.
