CAUTION on storage
When storing the control valve, pay attention to the following precautions
of caution:
• A Control valve that has been packed in a cardboard box should be stored
indoors at normal temperature and humidity.
• A Control valve that has been packed in a wooden crate should be stored
indoors at normal temperature and humidity as a rule. In the event of
outdoor storage, open the crate, verify specifications and cover with
polyethylene protecting sheet.
• When storing a used valve, follow the procedures as described below:
(1) Flush out the process fluid from inside the valve body and dry,
(2) When there is a possibility of the valve body rusting, preservation
treatment should be given,
(3) To prevent water from getting in the instrument, cover pneumatic
tubing connection and electric connector with watertight cap or tape.
Also, protect connector threads,
(4) Place flange cap on the end of pipe connecting surface (flange face,
butt welding connections) to avoid possible damage.

4. Installation
4-1. Installation environments
CAUTION
• Ensure sufficient space for easy
and safe operation and
maintenance of control valve.
• Avoid installing valve in a
location where vibration or
external stress may impair
proper valve functions.
If necessary, make
appropriate provisions
against these.
• Consider providing a
support for the valve so that
the process piping is not
burdened with the excessive
weight of valve, or provide
supports on the upstream
and downstream pipe runs.
• Provide a cover or protective
fence around valve installation
when a valve is installed facing a path or if physical contact with valve is
expected.
• Do not install a valve where it may be submerged water, or snow or where
freezing may take place.
• Provide a wall for protection against heat radiation.
• Provide measures to protect valve against salt spray or corrosive
atmospheres.
• To stop operation of the Flowmeter:
- Switch the control equipment connected to the flowmeter to manual
control.
- Turn off power to the Converter.
CAUTION
• In order to guard against accident while handling the valve, always wear
safety gloves, goggles and safety shoes.

Prior to installation work, follow the items of caution as described below:
CAUTION
• Check and confirm that there is no external damage to the valve (body,
actuator, accessories).
• heck and confirm that there is no damage on pipe connecting flanges or
butt welding connections,
• Ensure that temperature of welded part of pipe has been reduced before
proceeding,
• Make sure that the flanges on pipe have been chamfered.
• Remove dust, sand, welding spatter or any other foreign matter from pipe
and clean out pipe. Any foreign matter will damage the valve seat and
reduces shutoff characteristics.
• Ensure that upstream and downstream pipe supports are sufficiently
strong. Otherwise, the valve's weight may cause leakage from flange
connections.
WARNING
• Operation of valve over and beyond the rated pressure or connection
other than recommended of specified connection may cause damage or
leakage which may result in serious injury.

Dirt, sand

4-2. Installation work
CAUTION
• Ensure that centers of upstream and downstream pipes are aligned when
pipe installation has been completed. Any mis-alignment of pipe will
distort the valve and will cause leakage from the connections. (Gasket)
• Make sure that the face to face dimension of pipe flanges is equal to face
to face dimension of valve body plus gasket thickness.
• Use proper gaskets for pipe flanges. Otherwise, process fluid may leak.
Always use new gaskets for pipe flanges that will meet process fluid
specifications, temperature and pressure conditions. Otherwise process
fluid leakage may occur.
• When flushing pipes, keep valve in the fully open position and do not
stroke valve. Welding spatter or foreign matters may damage valve.

WARNING
When installing a valve on a pipe, keep hands and feet away from valve
body's bottom or between flanges to avoid physical injury.
When reinstalling the valve after inspection, maintenance or modification,
flush out process fluid remaining in the pipe or replace it with safer liquid.

4-3. Pneumatic piping and electric work
CAUTION
• Pneumatic tubing should be sized so as not to cause dropping of air
pressure when control valve is in operation, Pneumatic tubing should
have an allowance in bend (use specialized tool) and bands should bind
parallel tubing.
• Only qualified persons should do electric work in accordance to electrical
facility engineering standards.
• Cable connections should be made to conform to the facility's conditions.
A suitable adaptor or packing should be selected to suit the outer
dimension of the completed installation.
• When using seal tape on pneumatic tubing, do not apply the tape on the
first two threads from the tip of connector. This may block air passage and
cause malfunction of valve.
• When using liquid packing (seize lock) on pneumatic tubing, care should
be exercised so as not to leak the liquid into tubing. It may block the air
passage, resulting in valve malfunction.
• Avoid electrical work in rainy weather or time of high humidity. Any
intrusion of water into connector or terminal will cause rusting and
electric leakage.
• Covers of accessories such as the positioner are provided with seal
packing (gasket). Exercise care so as not to misplace or lose them while
electric work is in progress.
• Exercise care so as not to lose fixing screws of accessories such as the
positioner. When tightening screws, ensure that packing is in place and
tighten screws with an even torque.
• Cable threads and conduit seal should be tightened so as to ensure that
water does not get in.

5. Caution disassembly, reassembly
5-1. Disassembly
CAUTION
• When disassembling a spring-incorporated
positioner, follow the prescribed procedure in
removing bolts and nuts. Otherwise, the spring
may pop out, resulting in physical injury.
• When the eye-bolts of actuator are used to
lift valve from pipe, ensure that the weight
limitation as described in manual is adhered to.
Otherwise, there is the danger of dropping the
valve,
• When removing trim (inner valve) from
the body, ensure that the proper type of
specialized tool is used. Refer to the instruction
manual for proper tools. Otherwise, the trim
may be damaged.
WARNING
• Before disassembling the valve, ensure that the
pressure within piping has been reduced to
atmospheric pressure. Flow out of process fluid
may cause physical injury.
• When disassembling the valve, flush out
interior of the valve or replace fluid inside.
Residual process fluid may cause physical
injury,
• Do not disassemble pneumatic actuator with
supply air on. Compressed air may cause
physical injury.
