3.4 TRANSPORT

Transport the gate valves on sheltered vehicles.

The DN65 to DN300 gate valves with soft seals shall be handled and installed on belt slings (see the example

diagram below) and secured from turning.

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.
