1, Stocking
Stocking(packed) :
Valve to kept/stored indoors under cool and dark
condition (temp:-5˚C 〜60˚C, humidity: less than 70%),
if valve not installed to pipings immediately after
delivery.
Stocking (un-packed) :
When valve to be stored without packing, any
excessive force to its actuator part to be avoided.
Cover-sheet to be put onto valve at dusty place. (Fig.2)
Stocking :
Apply anti-rust to the plated-parts (indicators, bolts
nuts worm shafts, etc…) once a year if valve is stored
for one year or longer.
2, Handling
Cares while handing :
When valve to be kept /stored under packed condition,
package(s) to be put on stable place so that collapse
of package(s) to be avoided. Upon carriage, valve to
be nicely loaded so that any collapse to valve could
be avoided. When valve to be carried after removing
packing, excessive force to valve to be avoided and
cover-sheet to be put onto valve in dusty-place. (Fig.3)
Trucking :
To use truck with canopy is recommended if possible.
Cover valve to prevent dust if a truck with no canopy
is used.
Sipping(seaborne) :
Use a container for shipping to protect valve from sea
breeze. Sea breeze will damage valve.
3, Un-packing
Un-packing :
Un-packing of valve to be recommended before its
installation to pipings. If valve stored being unpacked
for long,dust or foreign matter will get into the valve. If
will cause malfunctions. (Fig.4)
Check disc position :
Make sure if valve is in the closed position when
package is opened.

1, Checking Valve Body
Check sizes and material :
Sizes & Specifications of Trim Materials are indicated
on package and valve, and re-confirmation of sizes/
specifications before its installation to pipings is
recommended.
Check piping sizes :
Check the valve sizes fit the piping sizes. (Fig.5)
Check the number and the sizes of bolts :
Before using bolts and nuts, apply a seizure preventive
to bolts and nuts.
2 , Welding Before Installation To Pipings
Cares when welding flanges :
Installation of the valve immediately after welding of
the flange to be avoided, and installation to be made
only after welded-part cooled down.
Welding of flange or reparing works through welding,
while keeping the valve installed to pipings, to be
avoided. (Fig.6)
Make sure welding work is completely done before
installation the valve to the piping. Flanges to check
and confirm on deflection or miscenter-alignment of
flange and no spatter sticked.
3, Check Piping Flanges
Make sure no deflection or damage to piping :
Make sure no deflection or miscenter-alignment of
flanges and no score or spatter stacked. Clean spatter
stacked on the edge of the flanges completely in order
not to damage the seat-ring.
Cleaning :
Flange surface is to be air-purged for cleaning. If
rust or foreign matter is sticking on the surface of the
flanges, wash the surface of the flanges in detergent.
After washing, make sure no detergent remains on the
seat-ring. If detergent remains on the seat-ring, it will
damage the seat-ring.
Make sure that no oil or detergent sticks to EPDM seat.

4, Cares Before Installation Valve To Piping
Installation place :
Application to heavy-vibrant positions to be avoided.
To keep enough space for maintenance work. (Fig.7)
lInstallation work :
Connect the valve and the piping flanges correctly.
Forcing the valve to insert between the piping flanges
to be avoided.
Gasket packing :
The insertion between the valve and the piping-flanges
shall be needed the gaskets. In inserting,adjust
both the valve and the gasket to the center of the
flanges accurately. Keep space of about 3mm to 5mm
between the valve to the piping-gasket (the flanges) on
each side. (Fig.8)
Do not insert the valve between the piping flanges
forcefully. And also, do not use the flexible material
such as rubber to the gasket, otherwise, we
recommend the joint seat as the piping-gasket.
Further, in using the special gasket such as the spiral
gasket, please contact to sales person in charge.
Disc position :
Keep the valve in closed position when installation to
the pipings.
Installation the valve to ab ent pipe :
Upon installation of the valve to the pipings, no define
limitation of direction of the valve being installed but,
under such condition as illustrated in Fig.8-1, direction
of stem to be cared.
Installation the valve to a return valve to a return valve, etc... :
When the valve to be installed directly to return valve,
pumps, etc…, there may be cases in which disc
touches to other upon its full opening. In this case,
short-pipe to be fixed before installation of the valve.
(Fig.9)

1, Installation Procedures To Pipings
1. Cleaning:
Remove foreign matter from part of the valve touches
surface of flanges by air blow.
2. Check the valve position :
Make sure the disc is in the closed position.
3. Suspend (Support) the valve :
Insert bolts into lower flange holes, and then put nuts
on either side of the bolts to support the valve.
4. Set jack bolts :
Keep space of about 3mm to 5mm between the valve
and the flanges on each side. (Fig.10)
5. Insert the valve :
Do not insert the valve between the piping flanges
forcefully.
6. Center the valve to the piping flanges :
Insert bolts into the flange holes to suspend the
valve,then center the valve to the flanges accurately.
7. Tighten up bolts:
Firstly, as Fig.10-1 (top and bottom),tighten the bottom
of the bolt A and B not to drop the valve. Then insert
other bolts. (Fig.10-1)
Tightening piping bolts is doing evenly and diagonally.
Unbalanced fastening among bolts causes any
leakage. From 1 to 8 is shown example of the order of
fastening bolts. (Fig.10-2)
8. Check the disc movement :
After installation of the valve,operate the valve (from/to
open and close) to make sure the disc dose not touch
any part of the pipings.
※
In case of that flow medium is steam, install the stem side as
the upstream of flow direction.
※
Regarding Model 541R and 541M,install the stem side as the
upstream of flow direction.

2, Cares After Installation to Pipings
Check leakage :
Before operation of the valve, pressure inside the pipings
to be raised and to make sure no-leakage between the
piping-flanges and the valve. When gas used as fluid,
use soaped water for checking leakage. However,
pressure inside the pipings not to be raised beyond the
valve specifications, and set the disc of the valve in the
open position while checking the leakage. (Fig.11)
Treatment for leakage:
In case of leakage, reduce the pressure firstly, and
then tightening the flange bolt again. Tightening bolts
is doing evenly and diagonally. Unbalanced fastening
among bolts causes any eakage.
3, Other Points to be cared
Trial run (Check-up run) :
Operate the valve by manual before operating.
Cares while operating the valve with a hand wheel :
Be sure to turn the hand wheel by the hand. Do not
turn the hand wheel with a wrench or lever in order not
to cause trouble.( Fig.12)
Do not use blank flange :
Keep the valve fully opened while pressure test, etc.
Do not use the fully closed valve as a blind flange.
Cares after pipings :
Regarding motorized valve, in operating by manual hand
wheel, make sure the main power is off before operating.
After returning electric operation mode, remove the lever
and put on the main power. (Fig.12-1)
Operating more than two actuators by one switch shall
cause malfunction due to wrap around circuit. So, Operate
one by one, and also,set up the relay nterface. (Fig.12-2)
Precaution
Opening/Closing the valve in short time causes the water
hammer which may damage the valve or the other instrument.
Please contact the person in charge if you use such a way.
In case that actuator and valve is soused by corrosive
fluid directly, protect with protection cover.
In case that control valve is installed to upstream side,
vibration of turbulent may damage it, so get space
from 3D to 5D.

1, Checkup
Periodic checkup :
Inspect the disc or seat-ring at least once a year.
Make sure no disc is corroded or weared. (Fig.13)
Long no use after installation :
If the valve is not to be used for extended periods
after installation, open and close it manually or
automatically at least once two weeks.
Trouble happened :
If valve operates inproperly, foreign matter or damage
to seat-ring or something may be of the cause of the
problem. Please see the trouble shooting chart shown
in P.15.
2, Removal From Pipings
Warning
Check pressure inside pipings before
removing the valve from pipings :
When the valve removes from pipings, make sure the
pressure inside the pipings is lowered.
In case of fluid remaining inside the pipings, drain it
out from the pipings. (Fig.14)
How to remove the valve from the pipings :
Set the valve in the closed position, then pull out
bolts and nuts. In doing this, remain a few bolts and
nuts in the lower holes of flanges to support the
valve. For easy-removal work,inserting jack bolts is
recommended.
