Piping
CAUTION
When installing this product, hold it in the
proper position and securely fasten it to the
pipes.
Excessive tightening or improper installation
position may damage the valve.
(1) Check that the model number of the product is
what you ordered. The model number is shown
on the label attached on the yoke.
(2) Install the valve so that fluid flows in the direction
pointed by the arrow on the valve body.
Refer to ● "Mounting position."
•
When piping, do not apply too much sealing
material, such as solidifying liquid and tape, to
the pipe connection sections.
•
Do not allow chippings, sealing material, etc. to
get into the pipes.
The foreign matter, such as chippings, seal
material for screwing the pipes, may be caught
in, resulting damages on the valve seat and the
valve may not be fully closed.
(3) Fully open the valve and flush the pipes at the
maximum flow rate. When fluid flows for the
first time, it is to clean out the foreign matter
and refuse in the pipes.
The valve is set to fully closed when it is shipped
from the factory.
CAUTION
After installation, make sure no fluid leaks
from the valve-pipe connections.
Improper piping may cause fluid leakage
outside of the valve.
Do not put a load or weight on this product.
Doing so may damage the product.
