Body and Trim Materials
The valve body and ends are castings made
from Stainless Steel
conforming to ASTM A351
CF3M which improves the
resistance to
intergranular corrosion
caused by welding.
Welded end castings have low
sulphur content
of 0.005~0.017% and ferite <
3%. The ball and
stem are from Stainless Steel
conforming to
AISI 316L. These materials
are offered for
Biochemical, pharmaceutical,
chemical and
food machine equipment.

Seats
A flexible seat design
provides tight shutoff at
high and low pressures,
reduces wear and valve
torque. The seats are
designed for low torque
giving bubble tight shutoff
and have no
equalizing pressure slots or
chamfers on the
perimeter. Other seat designs
available are
Cavity Filler seats for
reducing dead volume in
the valve cavity.
|
Stem & Ball
All valves have blowout
proof stems. And a
highly
polished solid ball
ensures tight shutoff
and
long service life.
The ball
orifice matches the
tube
internal diameter to
reduce product
deposits
being trapped in the
line
and minimize pressure
drop. Its post
leading
edges are rounded to
eliminate excessive
wear
of the seats.

End
Connections
All ends are one-piece castings and are
machined on all
wetted parts to high garde
finish. The standard
ends are tube end, hygienic
clamp or extended
tube end.
