These valves are type approved by DNV
as per API 607, as double offset providing
excellent controllability, bubble tight shut
off, greater seat life and standard smooth
operation.
TRIPLE OFFSET
BUTTERFLY VALVE
Triple offset metal seated butterfly
valves with unique seat geometry disc
shaft engagement provide high cycle
life under extreme temperature
conditions with metal to metal tight

DESCRIPTION
APPLICATION
RF
Raised Face
Sealing on RF flanges is by flat non-metallic
gaskets fitted within the bolts of the flanges.
Surface finish is controlled depending on the
type of gaskets being used.
Typically used for low pressure (class 150-300-600)
RJ
Ring Joint
Ring type metal gaskets must be used on this
type of flange facing.
Typically used for high pressure (class
900-1500-2500-API 6A)
HUB
This coupling requires bolting, clamps and
a seal ring. As different designs are produced
by different manufacturers, we always ask
the customer to supply the HUB machining
drawing.
Typically used for high pressure (class
900-1500-2500-API 6A)
Butt Welding
This construction offers the highest verifiable
integrity of welding as BW connections are easy
to radiograph. Different schedules can be
supplied.
BW ends are generally used when the possibility
of fluid leakage must be eliminated.
