DIN Side Entry Cast & Forged Floating Ball Valve

DIN Side Entry Cast & Forged Floating Ball Valve

    The YFL DIN side entry cast & forged floating ball valve has a floating ball supported by two seats.

    The pressure of media will force the ball to press onto the seat seal ring at the outlet side to make sure tight seal at the outlet.

    The pressure of media is all transferred to the seat through the ball.

    When the pressure of media is high, the seat can’t stand the high pressure and there will be some displacements of ball. 
    The YFL split body floating ball valve is only suitable for low & middle pressure and small size working condition.
