a
IMPORTANT:
•
The top and the terminal covers might be corroded by chemicals and organic solvent or their vapor. Do not
expose the ACTIVAL to such substances/vapor.
•
When the ACTIVAL is used for steam humidifying, install a valve interlocking with air-conditioning unit on the
in ow side in case the ACTIVAL gets damaged.
•
Although the ACTIVAL can be used in high humidity environments (max. 95 %RH), do not immerse the
actuator in water.
•
Although the ACTIVAL can be used outdoors, be sure not to expose the ACTIVAL to direct sunlight.
Install the ACTIVAL in a position allowing easy access for maintenance and inspection. Fig. 1 shows the minimum
•
clearance for maintenance and inspection. When installing the ACTIVAL in a ceiling space, provide an access hole within
the 50 cm radius of the ACTIVAL. And, place a drain pan under the valve.
Do not mount the ACTIVAL on a pipe where water hammer occurs, or where solid objects including slug may accumulate.
•
zMounting position
The ACTIVAL can be mounted in any position ranging from upright to sideways (90° tilted). The ACTIVAL should be installed
with its actuator vertically positioned above the valve body. (See Fig. 3.) However, the ACTIVAL must be installed always in
upright position outdoors.

zPiping
Check that the model number of the product is what you ordered. The model number is shown on the label attached to
•
the yoke.
Install a bypass pipe and gate valves on the inow, outow, and bypass sides. Also, install a strainer with 40 or more
•
meshes (with 80 or more meshes recommended for steam control) on the inow side.
When installing the ACTIVAL to the pipes, do not allow any object, such as chips, to get inside a pipe or valve. Valve
•
cannot fully close, or the valve seat may get damaged causing uid leakage, due to an object jammed inside the valve.
When piping, do not apply too much sealing material, such as solidifying liquid and tape, to the pipe connection sections
•
so that these materials ow into the valve. Valve cannot fully closes, or the valve seat may get damaged causing uid
leakage, due to the sealing material jammed inside the valve.
Before activating the ACTIVAL, fully open (in 100 % position) the valve and ush the pipes (with the ACTIVAL installed) at
•
the maximum ow rate to remove all the foreign substances. (Factory preset position: 100 %)
For steam control, drain retained water (condensate) in piping. Install a trap on a pipe run which may retain condensate.
•
Condensate may cause water hummer or damage the valve and piping.
zHeat insulation
Do not apply heat insulation to the actuator or to the yoke, as shows in Fig. 2. If the yoke and the actuator are covered
with insulation material, the pointer cannot be checked and may be distorted.
zFactory preset position
The actuator shaft is positioned at 100 % (in fully open position) for shipment. The shaft is thus completely turned clockwise,
and the pointer points at ‘100’. (See Fig. 4.)
Figure 4. Pointer position for shipment
zManually opening/closing the ACTIVAL
IMPORTANT:
Manually opening/closing the ACTIVAL with the power (24 V AC) applied may damage the actuator.
•
To manually open/close the ACTIVAL, do not turn the joint beyond the fully open (100)/closed (0) mark.
•
To manually open/close the ACTIVAL, slowly turn the joint. If shock is sent to the actuator, the actuator may
•
get damaged.
Disconnect the power from the ACTIVAL before manually operating the ACTIVAL. As shown in Fig. 5, from the front of the
ACTIVAL, hold the joint using a tool such as a wrench, and turn the joint slowly toward the set position.

zProcedure to change the actuator mounting position
IMPORTANT:
Do not change the combination of the valve, yoke, and actuator.
•
Set the ACTIVAL (actuator and valve) in 100 % position when changing the mounting position. If the valve in
•
0 % position is assembled with the actuator in 100 % position, the actuator puts torque on the closed valve,
and the gear of the actuator gets damaged.
1) Remove the screws connecting the actuator and the yoke. Lift the actuator and detach it from the yoke. Make sure that
the groove on the top of the valve stem is parallel to the pipes (indicating the valve in 100 % position). <Step 1 in Fig. 6>
2) Remove the screws connecting the yoke and the valve. <Step 2 in Fig. 6>
3) Change the facing direction of the yoke. The yoke and actuator can be horizontally rotated every 90° (0°/90°/180°/270°
from the factory preset position) to mount onto the valve.
4) A thermal insulation sheet is inserted between the yoke and the valve. When changing the mounting positions, reinsert
the sheet and then t the yoke into the new mounting position.
5) Before xing the yoke to the valve with the screws, check that the actuator engages correctly with the valve stem (at the
new mounting position). Check that the pointer of the actuator indicates 100 % position as well. Then, x the yoke to the
valve. <Step 3 in Fig. 6>
6) Mount the actuator. Place the actuator, with its facing direction changed, on the yoke, and x them with the screws.
