Butterfly Valves
Butterfly Valves
Butterfly valves are the
most specified valves type for moderate-duty conditions in pipe sizes of two
inches and larger. Their reduced weight, reliable bubble-tight shut-off, ease of
operation and automation allowed them to displace gate valves in traditional
applications. Bi-directions shut-off is one of the hallmarks of butterfly
valves. Continuing development of the butterfly valves is making it possible to
use them in aggressive applications that previously were the exclusive domain of
gate and globe valves.
We have six series of butterfly valves .The fig number are BV1000, BV2000, BV3000,
BV4000, BV5000, BV6000. BV1000 to BV4000 series are concentric (center line)
with resilient seat butterfly valves. BV5000 series is flanged butterfly
valves. BV6000 is metal seal butterfly valves. Our BV1000 to BV3000 butterfly valves are available in wafer and lug
type. BV4000 only refer to
the wafer type. Wafer valves can be installed between two flanges using bolts or
nuts and studs, while lug style valves have metal inserts installed in the
valves's bolt holes and the valves is installed between two flanges using a
separate set of bolts for each flange.
How to specify our
BV1000,BV2000,BV3000,BV4000.BV1000 butterfly valves is with backed-up seat and
BV2000 with the soft seat. We call BV3000 slim-disc butterfly valves. In addition
to the feature of the butterfly valves, it has strong corrosion resistance and
no-pin. BV4000 is industry butterfly valves. Our butterfly valves upper flanges
are suitable for all types of valves fitted with electric, gearbox, manual and
pneumatic actuators. The connection dimensions of side flanges are accordance
with standard dimensions from each country. They are suitable for the pressure
of 0.6MPa, 1.0Mpa and 1.6Mpa.
