4 ASSEMBLY AND INSTALLATION
4.1 ASSEMBLY GUIDELINES
The TYPE 2502 and TYPE 2511 gate valves with soft seals and position indicator can be installed in
surface 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. Assemble
with consideration to pressure and temperature compensation of the pipeline. The valve assembled and adjusted
by the manufacturer is ready for installation. Any dismantling of the valve components may result in loss of seal.
