S
torage of Butterfly Valve Assemblie
s
● Assemblies must be stored indoors, protected from the elements.
●
Materials received on job sites that have long installation lead
times should receive extra protection from construction damage.
●
Resilient seats must be protected from abrasion, cuttin
g
and nick
-
ing, as this will damage the liner and may cause flange area leaks.
● Electric actuators cannot be stored in wet, damp or caustic areas
.
●
Do not store construction material on top of valve assemblies
.
Installati
o
n Practice
s
●
HD(U) series butterfly valves are designed to be installed between
ANSI 125/150 flat-faced, raised face, slip-on or weld neck flanges.
●
Valve should be installed a minimum of 10
p
i
p
e diameters
from upstream or downstream elbows, strainers, pumps, etc
.

●
For applications in which there is a possibility of sediment in the
flow
,
the valve should be installed with the stem in a horizontal
position and the bottom of the disc should close FR
O
M the down-
s
tream side, rather than from the u
p
stream side.
●
Make sure the flange faces are clean and free of rust, scale and
debris to prevent damage to the liner face.
●
Do NOT use flange gaskets on HD
(
U
)
series BF valves.
(
Fig. 1a
)
● Follow the recommended flange bolting sequence.

● Mount flanges on both sides of valve body and install bolts to
p
roperly align valve body and both flanges.
● Install the valve with the disc in the “Almost Closed” position (Fig. 1
)
●
Do not use any flange gaskets (Fig. 1a)
● Make sure the valve liner and flange internal diameters are in
alignment. (Fig. 2)
