⌈DISTINCTIVE FEATURES⌋
•Double Offset Design
•High Performance Valve
•API **9 Butterfly Valve
•C.S Butterfly
Valve
•Wafer, Lug or Flanged
•Resilient Seat
•Uni or Bi directional Seal
•Replaceable Seat Ring
⌈ MAIN CHARACTERISTICS ⌋
•Glofa High Performance Double Offset Butterfly Valve are designed
of double eccentric structure that the centerline of the stem are
deviated from the centerline of the disc and valve body centerline.
The structure may get the disc separated off the valve seat rapidly
when opening the valve, which could elinimate the over compressure
and rub between the valve disc and seat greatly, also reduce the
opening resistance and decrease the abrasion, improving the seat
service life. The large reduce on abrasion also enable the double
offset butterfly valve made in metal seated, expanding its
application in high temperature fileds. The disc of High
Performance Double Offset Butterfly Valve are with structure of
double slab disc type and mutiple passageway, each water flow could
be mutually restricted and get balanced, resulting in avoiding the
disc shaking and ensure the valve\'s stability.
⌈ DESIGN
ADVANTAGES ⌋
•The butterfly valve with above unique structures could get more
and more tighte when it is continuely shutt off. When opening the
valve, the disc could get separated from the valve seat completely
just by rotating the stem slightly, decreasing the friction a lot
and the seal get more tight, reliable, extending its durability.
The type butterfly valve have another features of minimun flow
resistance with good hydraulic characteristics, the flow
characteristics is approximately slanted straight line which make
the butterfly with good capability of energy
conservation.
