For Chemical Industry Spheroidal Ductile Iron DN200 Ball Valve
Introduction to Ductile Iron Ball Valve
The opening and closing parts (ball) of ductile iron ball valve are
driven by the valve stem and rotate around the axis of the ball
valve. It can also be used for fluid regulation and control. There
is a strong shear force between the hard-sealed V-shaped ball core
and the metal valve seat with hard alloy overlay, which is
particularly suitable for media containing fibers, tiny solid
particles, etc.
Features
The main features of the ball valve are its compact structure, easy
operation and maintenance, and it is suitable for general working
media such as water, solvents, acids and natural gas, and is also
suitable for media with different working conditions, such as
oxygen, hydrogen peroxide, hydrogen monoxide and styrene. The ball
valve body can be integral or combined. The closing part of the
ball valve is a sphere, which is a valve that rotates around the
center line of the valve body to achieve opening and closing.
