5.4. LOCATION
The valve should be installed in a manner that permits to be cleaned, inspected and self-draining. Allow
sufficient spacer around the valve for adequate review, dismantling and maintenance. See table in section
Installation shall allow that removable parts shall be readily disassembled.
5.5. DIRECTION OF FLOW
The following image indicates the recommended direction for product flow, as well as the direction of closing.
Following these indications will prevent water hammer and its consequences to the extent possible, which can
occur when valves close.
The recommended direction will always be contrary to the movement of valve closing, that is, when the valve is
closing, the valve will always work against the pressure of the fluid.
5.6. GENERAL INSTALLATION
After the location of the valve is defined, the pipe can be joined by welding the valve body or using fittings. In
this case, do not forget the seals, and tighten the unions properly.
Before starting to weld the valve bodies to the pipe, disassemble the valve to prevent damage to the joints,
following the instructions in section
8.4. Assembly and disassembly of the valve
Avoid using excessive force when assembling the valves, and pay special attention to:
vibrations that may be produced on the facility,
thermal dilation that the pipe may undergo when hot fluids are circulating,
the weight that the pipe can support,
excessive welding current.
