4 ASSEMBLY AND INSTALLATION
4.1 ASSEMBLY GUIDELINES
The Type BA P/N cast-iron flanged antipollution
check
valves
can be
installed in
overground pipelines in horizontal orientation as shown in the following
figure. The flanged
valves
are
designed
for installation between flanged pipe connections
of a
matching
size. Note
that
the
system must
not
expose
the
valve
to
bending or tensile stress from
loading with the
unsupported
pipeline
s
ections
.
It is recommended to perform installation works
considering pipeline compensation due to temperature and pressure. The valve assembled and delivered
by the manufacturer is ready for installation. Disassembly
of the
valve components
without
proper
care
may
result
in
loss
of
integrity.
4.2 ASSEMBLY INSTRUCTIONS
Before attempting to install the valve, check the technical and commercial documents
delivered with the product to verify that the media, and especially pipeline operating parameters (flow rate
range) comply with the manufacturer's declaration. Any change in the operating conditions must be consulted
with the valve manufacturer beforehand.
Before attempting to assemble the valve, remove the main bore plugs, check the inner
surfaces of the valve and thoroughly flush with water, if necessary.
Caution! If the product has mechanical damage, do not install it in the pipeline.
