INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
HANDLING & STORAGE
HANDLING
Proper care in handling the valve should be taken to
prevent damage. Do not drop or throw it.
STORAGE
• Store the valve in the protected area from dust,
moisture, and direct sunlight.
If possible, should be kept in the original packaging.
• Do not remove a dust proof cap until the piping.
CHECKING
• Check the product code before installation.
• Confirm that there is no screw loose or part
deformation.
INSTALLATION
PRECAUTIONS
• Before installing, clean pipe and valve ends. Make
sure they are free of dirt, dust and etc.
• DN valve is shipped closed. (TACDN is closed with a
manual unit. Without a manual is open.)
• The butterfly valve should be piped upstream of the
elbow. When piping downstream from the elbow,
considered a straight line that is at least five times the
length of the pipe.
• The valve stem should be mounted perpendicular to
the flow for biased fluid.
• Disc interference may also occur when valve is
installed in pipeline with smaller than normal inside
diameter such as thick wall pipe, or lining pipe.
Suitable corrective measurement must be taken
(taper boring the pipe or pipe liner, etc.)
PIPING FLANGES
• DN valve has a flow direction. Install the valve
accordingly.
• Gasket should be selected appropriately to suit the
fluid, pressure and temperature. Use spring washer to
prevent from decreasing surface pressure gasket
when the temperature change happens frequently.
• Wafer type butterfly valve is put between two seats of
flanged-end and tightened with long bolts.
• Before bolts are tightened, valve should be centered
within the bolts to prevent possible disc interference or
damage by contact with the pipe or flange.
• Tighten all bolts using crossover method to load the
joint evenly.
• If a plastic flange used, do not over-tighten the bolts,
as this may deform the flange and cause leakage.
ENVIRONMENT
• Do not install in place where corrosive gas is present
or where vibration is heavy (0.5 G or more).
• When radiant heat causes the surface temperature of
the control unit to exceed 50 °C, provide an
appropriate shielding plate.
• If there is a possibility that the fluid and drive part
freeze, please take measures to prevent freezing.
• For single-acting type, prevent water and dust from
coming into air exit.
POSITIONING
Should be positioned through 90° upward from
horizontal. Provide space around the product to allow
manual operation, inspection and replacement work.
CAUTIONS FOR MAINTENANCE
Do not keep warm for maintenance of the valve gland.
TIGHTEN THE GLAND NUTS
• Check that there is no leakage from the gland
packing.
• If it leakage, tighten gland nuts by alternately.
Do not over-tighten the gland nuts.

INSTALLATION, OPERATION & MAINTENANCE INSTRUCTIONS
AIR PIPING
• Pneumatic actuator has an air supply ports to operate
piston.
Double-acting type
TAD-040 : Rc 1/8
TAD-050 to 160 : Rc 1/4
Single-acting type
TAO / TAC : Rc 1/4
• Piping of double-acting type is connected by seal tape
on PORT A / B. Piping of single-acting type is put seal
tape only on the air intake port.
• The air supply port may be damaged if over-tightened.
Please lightly tighten by hand.
• Never put anything on the actuator or make it into a
foothold.
OPERATION
AIR SOURCE
• Use the filtered dry air (less than 40 ).
• Extra attention is needed where it's cold climate
(below 5 °C).
• When air pressure is high, reduce it to standard
pressure (0.4 to 0.7 MPa). Air pressure should not
exceed 0.7 MPa during operation test.
• Capacity of compressor and air tank are to be
calculated by capacity of piping and air consumption.
A margin of 30 % is required.
TEST OPERATION
Check the operation of pneumatic actuator before
fluid enters the piping.
Double-acting
type
Stop the air from the air source.
Release the residual pressure in the
air cylinder. Open the air equalizer.
Move the manual shaft of actuator
with a wrench.
Single-acting
type
Send the standard pressure air.
Confirm the opening / closing
operation by slowly moving the
actuator.
TESTING
After piping, check following points.
• Piping is correct.
• Air or fluid leakage from connection. Flow direction
of air is correct.
• Air pressure is in the range.
• Nothing interferes with operation when limit switch
or solenoid valve is attached.
ATTENTION
The opening and closing operation of the pneumatic
actuator is fast, which may affect the product life.
Please adjust the operation time of pneumatic
actuator using a speed controller.
Valve size Adjustment of operation time.
080 to 300 mm More than 2 seconds.
MANUAL OPERATION
• Double-acting; stop the air supply and do not leave
the air inside of cylinder.
• Single-acting; cannot be operated manually.
Optional code with the handle: TAO-MT / TAC-MT.
• Before automatic operation, be sure to remove
wrench.
OPERATION (TAD)
After turning air pressure to 0, turn manual shaft
slowly with a smooth-jawed wrench to check the
direction of OPEN/SHUT position.
MAINTENANCE
• Do the routine maintenance at least once in half a
year.
• Do not set or take spring unit parts apart after
installing the pneumatic single-acting actuator.
Can be used with no oil supply.
• Confirm the air leakage.
• Confirm the air supply pressure.
• Confirm the dirt or grit inside of cylinder.
Lubrication Procedure (TAD / TAO / TAC)
In case of lubricating, use turbine oil or the
equivalent through a lubricator. (ISO VG 32.46).
Once lubricate, do the regularly.
Inspection items
• Confirm operation of opening and closing.
• Confirm whether screws are loose or not.
• Confirm the fluid temperature or pressure.
• Confirm the leak from valve stem.
• Confirm the bolt tightening torque.
