Our 300LB Cast Steel Floating Ball Valve With ANSI 300# full bore 2 piece Ball Valve. A WCB body and stainless steel 316 ball, with RPTFE seats for High Temperatures. Principle of the cast steel floating ball valve: This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet. floating ball valve is mainly used in middle or low pressure application.
