Precautions during installation and inspection
Warning
(1) Because of heavy weight, hold the valve with lifting equipment while
piping. Refer to
“
3. Dimensions and weights
”
table for the valve weight.
※
Failure to do so may result in injury due to dropping the valve.
Caution
(1)
When installing, confirm if the direction of fluid flow matches with inlet and
outlet port of the product respectively.
※
If installed in opposite direction, it will not function as designed.
(2)
Carry out the securing of pipes and the product properly.
※
Excessive piping stress may cause the deformation of strainer.
(3)
When installing, reserve the space shown in Figure-4 for the maintenance and
checking (cleaning of the screen).
※
It will be impossible to carry out the maintenance and inspection (cleaning of
the screen).
(4)
Do not apply excessive load, torque or vibration to the valve.
※
The fluid may leak from strainer.
(5)
Carry out the connection with pipes properly.
※
Improper piping connection may cause the leakage of fluid due to vibration
or other cause. With some kind of fluid, there will be a danger of personnel
being scalded.
※
The fluid flowed out of pipe end may cause some material damages.
（１）
In case installing pressure gauge at backward and forward of strainer, clogging
can be checked by differential pressure.

（２）
Install strainer with the cap parts facing downward.
［

．
Example of
piping figure 1
］
However, install strainer with cap parts facing sideways in
case of steam piping so that condensate accumulation is minimized.

（３）
If fluid flows from bottom to top, install a blow valve in order to remove scale
accumulated at the bottom of riser pipe.
