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 sections. 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.
