Company
Construction
Stainless steel disc
ensures blow-out proof
stem
V-ring provides a weather
seal
O-ring as secondary seal-
ing ensures that media
does not escape to the
atmosphere through the
stem guide
Disc with two-piece shaft
construction enhances the
flow capacity of the valve.
The shape of the disc
provides lower torque and
prolongs the life span of
the valve
PTFE/graphite bearing
ensures perfect turning
and centric positioning of
the stem. The bearing is
placed inside the disc
Seat vulcanized to a
phenol back-up ring which
makes seat replacement
very easy. The tolerances
assure 100% tightness
at full differential pres-
sure. The valve is ideal for
vacuum applications and
mounting between flanges
is easily done
Square stem - angled at
45°. Material is AISI 420
or AISI 431 to insure high
torque transmission with-
out damage. Smooth finish
surface
PTFE bearing ensures
perfect turning and centric
positioning of the stem.
The sleeve bearing pro-
vides excellent support
if actuators are used for
automation purposes
High quality GGG40 steel
body with standard ISO
5211 mounting flange.
Body is coated according
to ISO 12944 C3 industrial
standard with 3 layer
Epoxy/Epoxy/PUR 160µ
Both Wafer and LUG has
fully changeable liner con-
struction.
LUG model has a specialy
designed grove to insure
uni-directional “end of line”
installation with full differ-
ential pressure
O-ring anti-dust type
Bottom plug ensures blow-
out proof design and acts
as a weather seal
Bottom stem in AISI 420 or
AISI 431 with smooth sur-
face finish
Unique seat wave line
rubber seat reduces the
torque of the valve and
extends the life span of
the sealing. DN40-DN300
