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.
