Butterfly valves for high performance applications are found in industries like:
Square stem - angled at 45°
Stainless steel disc ensures
blow-out proof stem.
V-ring provides a weather seal.
PTFE bearing ensures perfect
turning and centric positioning
of the stem. The sleeve bearing
provides excellent support if
actuators are used for automa-
tion purposes.
V-ring as secondary sealing
ensures that media does not
escape to the atmosphere
through the stem guide.
Disc with two-piece shaft con-
struction 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.
O-ring anti-dust type.
ISO 5211
Multi-standard alignment holes help
mount the valves.
Seat vulcanized to a phenol back-up
ring which makes seat replacement
very easy. The tolerances assure
100% tightness at full differential
pressure. The valve is ideal for vacu-
um applications and mounting be-
tween flanges is easily done.
V-ring provides a secondary sealing,
preventing leakage to and from the
stem.
Unique seat wave line rubber
seat reduces the torque of the
valve and extends the life span
of the sealing.
