GWC Triple Offset Butterfly Valve is from the family of quarter-turn valves.
This valve is designed and manufactured to meet API 609 and ASME B16.34
specifications.
DESCRIPTION OF VALVE
 Sizes from 3” (80mm) to 48” (1200mm) are standard.
 150, 300 & 600 ASME Class ratings are standard.
 Wafer, Lug and Flanged constructions.
 Face-to-Face lengths are as per ASME
B16.10, API 609, ISO 5752 and BS5155
are available.
 Testing according to API 598. Other testing
standards such as ISO 5208 are available
upon request.
 Triple offset valves are bidirectional.
 Fire Safe certified as per API 607.
 Gear operator can be attached with bracket
with the ISO 5211 bolt pattern.
 GWC Triple Offset Butterfly Valves have a
center disc mounted to the vertical stem with
disc pins.
 The disc is mounted eccentric from the stem
and valve axis.
 When the stem rotates, the disc rotates
about the vertical stem axis to close or open
the valve.
 The Body has a metal seat with laminated
graphite.
 Conical body seat and disc for creating third
offset to reduce the seat wear.
 The stem is a blowout proof design which
prevents the stem from blowing out in case
of stem breakage.
 The seat is retained by the seat retainer
in the seat pocket with retainer screws,
which prevents the seat from blow-out
during operation.
 The seat can be changed between soft seat,
metal seat and fire safe seat
without changing the seat retainer which is
bolted to the body.
 Tight shutoff leakage class VI is achievable.
 High temperature up to 750F (400C).
STANDARD FEATURES

5
 GWC Triple Offset Butterfly Valve has
a unique seat and seat retainer design to
minimize the seat movement.
 The seat retainer is bolted to the body, the
retainer plate holds the seat in the seat pocket
and hence a seat blow-out is avoided.
BLOW-OUT PROOF SEAT
 The 1st offset
increases the
sealing capacity.
 2nd offset
reduces the
running torque
and friction
between disc
and seat.
 3rd offset,
the cone shaped
disc seat and
body seat
help prevent
abrasion of
the seat.
TRIPLE ECCENTRIC DISC-SHAFT
LAMINATED
BODY SEAT
 Metallic Seat (red color)
are laminated with graphite
(black color).
 Laminated seat fixed to
the body does not face the
flow directly. Due to this
feature the seat wear is
minimized and hence the
seat lasts longer.
 The conical surface of the
disc develops less friction to
the fluid flow when the valve
is in the fully open position
and allows the flow to move
smoothly around the seat.
Hence the pressure drop will
be minimized.
