Two Pieces Forged Steel Floating Ball Valve

Description:

Principle of the forged steel floating ball valve: This kind of forging 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.
