2. Installation
1.
It is highly recommended to install the pigging valve with the stem in the vertical
position.
2.
Ensure the Pig Valve matches the nominal size and pressure rating of the piping
system.
3.
Check and clean all sealing surfaces and they MUST be free of foreign materials or
damage.
4.
Identify the ‘’launcher’’ / ‘’receiver” pigging valve and flow direction. On the marking
side of the body (opposite the closure) there is a flow arrow. If the catcher plate (An
indicated tag located on the flange) is installed on the body at the head (point) end
of the arrow it is a receiver valve and if the catcher plate is installed on the body at
the tail end of the arrow it is a launcher valve (please refer to the figure 1). Ensure
the correct flow direction.
5.
The valve should be properly supported to not add weight or stress to the piping
system. The added valve weight can cause distortion of the pipeline and/or valve
body.
6.
Do not attempt to correct pipeline misalignment by means of flange bolting
adjustments.
7.
Do not allow the valves to carry the weight of the pipeline to avoid distortion and
jamming.
8.
Pigging Valve MUST be installed in the “Fully Open” position.
