4 ASSEMBLY AND INSTALLATION
4.1 ASSEMBLY GUIDELINES
The Type 2112 flanged cast iron gate valves can be installed in underground or overground pipelines
both in horizontal or vertical orientation. The listed products are suitable for joining with the flanged ends of
pipelines with the size equal to that of the valve flanges. Note that the system must not expose the (gate) valve to
bending or tensile stress from loading with the weight of unsupported pipeline sections. It is recommended to
perform installation works considering pipeline compensation due to temperature and pressure. The valve
assembled and adjusted by the manufacturer is ready for installation. Any dismantling of the valve components
may result in loss of seal.
