Betterfly Valve |
 |
|
FLOEC Butterfly Valves, wafer type with integrally moulded
elastomer body sleeve are designed for longer life
and trouble free performance. Integrally moulded sleeve
ensures perfect resistance against friction between
the disc and the sleeve.
Special
Features
-
Integrally
moulded elastomer liner restricts dislocation
of seat and ensures longer life.
-
Flat
surface on the disc and the liner at the top and
bottom ensures perfect sealing between body, disc
and stem.
-
Elastomer
body liner is extended deep into the top and bottom
of disc shaft passages with integral 'O' ring
to ensure no working media contacts the body material,
thus ensures longer life for body.
-
A
primary seal provided at the top end of the body
prevents entry of any foreign particles in the
Valve, thus ensures longer life for Stem and smooth
operation.
-
Valve
disc is designed to ensure smooth straight through
flow, which reduces pressure drop across the Valve.
-
Close
tolerance maintained between the liner, disc and
stem reduces operation torque and ensures smooth
and easy operation.
-
Integrally
moulded liner got integral gasket with it at both
ends of the Valve which eliminates requirement
of Valve mounting gaskets.
-
Designed
and manufactured to conform BS 5155/API 609
-
Suitable
to mount between flanges of ANSI B16.5 [150#]
or BS-10 Table D/E
-
Pneumatic
and Electrical actuated Valves are available on
demand.
-
Top
platform of the Valve is suitable to mount actuator
or manual gearbox directly.
-
Flow
Control Lever is provided to facilitate fine control
of flow.
