Precautions for installation
CAUTION
•
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety
standards.
•
Install the product in the proper position as specified in this manual.
Excessively tight connection to a pipe or improper installation position might damage the product.
•
Use full gaskets for the flat face flanges.
Failure to do so might damage the valve or cause fluid leakage.
•
When installing the product with flange gasket, do not allow the flange gasket to go inside the pipe.
Doing so might cause incorrect measurement and control of flow.
•
Do not use rubber gaskets.
Doing so might cause incorrect measurement and control of flow.
•
After installation, make sure no fluid leaks from the valve-pipe connections.
Incorrect installation might cause fluid leakage.
•
Do not allow any foreign objects inside the pipes during installation. Flush the piping to remove the foreign objects
after installation.
Foreign objects inside the piping might damage the product.
•
Install the valve to the pipe so that they are electrically connected at the same potential. If the valve and the pipe
are electrically isolated, noise will be generated, causing incorrect measurement and control of flow.
IMPORTANT:
Model FVY5160J requires straight pipe runs (valve diameter
×
2 long) on the inlet and outlet sides for accurate
flow measuring.
•
Model FVY5160J is the valve and actuator integrated into a single unit. Do not combine the valve with any other actuator, or
do not combine the actuator with any other valve.
•
To remove foreign objects inside the pipes, install a strainer with 40 or more meshes on the inflow side of each valve. If the
strainers cannot be installed on the inflow side of each valve, install it on the pipe diverting sections (sections diverting from
main piping system to sub piping system).
•
Install the valve so that the flow direction of process fluid agrees with the arrow indicated on the valve body.
