Warning!
•
Valve should not be used for combustible
g
as applications.
G
as leaks and explosions
may result. Do not install in systems, which exceed the ratin

• Valve assembly location must be within ambient ratin

• Followin

standard procedure, a strainer should be installed be

or in another a

riate
p
lace in the s

stem.
• Visual access must be
p
rovided. Assembl
y
must be accessible
f
or routine schedule
service. Contractor should provide unions for removal from line and isolation valves
.
•
Avoid excessive stresses. Mechanical support must be provided where reducers have
b
een used and the piping system may have less structural integrity than
f
ull pipe sizes.
•
S
uffi cient upstream and downstream piping runs must be provided to ensure proper
v
alve capacity and
fl
ow response. Five diameters in each direction are recommended.
•
Life span of valve stems and
O
-rings is dependent on maintaining non-damaging
conditions. Poor water treatment or
fi
ltration, corrosion, scale, other particulate can
r
esu
