Precautions for installation
WARNING
Some of the product models weigh more than 40 lb (18.1 kg). Carefully move the product with a vehicle or enough
manpower in an appropriate manner. Careless lift or accidental drop of the product might cause injury or product
damage.
CAUTION
Keep the products in package for storage. Failure to do so might damage or stain the products.
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
For installation, do not mount the valve in an improper position or overtighten the bolts on the flange. Doing so might
damage the product.
Install the product to a pipe so that they are electrically connected at the same potential. If the valve and the pipe are
electrically isolated, noise might be generated, causing incorrect measurement and control of flow.
Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer on the inflow side
of the piping. Flush the piping to remove the foreign objects after installation. Foreign objects inside the piping might
damage the product.
After installation, make sure no fluid leaks from the valve-pipe connections. Incorrect installation might cause fluid
leakage
IMPORTANT:
This product requires straight pipe runs (valve diameter
2 long) on the inlet and outlet sides for accurate flow
measuring.
When installing the product with flange gasket, do not use the rubber gasket or the gasket that goes inside the
pipe. Doing so might cause incorrect measurement and control of flow.
Model FVY5137J 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 product so that the flow direction of process fluid agrees with the arrow indicated on its valve body.
