Installation
Precautions for installation
CAUTION
•Disconnect power from ACTIVAL before performing any wiring or maintenance (installation) to prevent equipment
damage.
•Install the ACTIVAL in the position as specified in this manual. Excessively tight connection of the valve to a pipe
and improper installation position may damage the valve.
•After installation, make sure no fluid leaks from the connecting parts of valve and pipes. Incorrect piping may
cause fluid leakage.

•Do not allow any foreign substance inside the piping. After piping installation, flush the piping so that no foreign
substance remains. Attach a strainer (with 40 or more meshes) in a pipe on the inflow side of the ACTIVAL to
prevent equipment damages.
•ACTIVAL Model VY51XXJ00 is the valve and actuator integrated into a single unit. Do not combine the valve with any other
actuator, or do not combine the actuator with any other valve.
•To remove foreign substances inside the pipes, install a strainer (with 80 or more meshes recommended for steam
application) on the inflow side of each valve. In case that the strainers cannot be installed on the inflow side of each valve,
install it on the pipe diverting sections (sections diverting from main piping system to sub piping system).
•Install the valve so that the flow direction of process fluid agrees with the arrow indicated on the valve body.
Installation location
CAUTION
•Avoid using the ACTIVAL in an atmosphere containing oxidizing or explosive gas since it may corrode the actuator,
valve, or their components.
•The actuator may malfunction if being exposed to high heat radiation. Do not install it near by steam coil or high
temperature water coil.
IMPORTANT:
•The covers might be corroded by some chemical and organic solvent/vapor. Do not clean the ACTIVAL using
such substances, or do not expose the ACTIVAL to such substances.
•When the ACTIVAL is used for steam humidifying, install a valve interlocking with air-conditioning unit on the
inflow 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 also 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. Figs 1 and 2 show 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.
Mounting 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. 4.) However, the ACTIVAL must be installed always in
upright position outdoors.

Piping
•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 inflow, outflow, and bypass sides. Also, install a strainer on the inflow 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 fluid 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 flow into the valve. Valve cannot fully closes, or the valve seat may get damaged causing fluid leakage,
due to the sealing material jammed inside the valve.
•Before activating the ACTIVAL, fully open (in 100 % position) the valve and flush the pipes at the maximum flow 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.
Heat insulation
Do not apply heat insulation to the actuator or to the yoke, as shows in Fig. 3. If the yoke and the actuator are covered
with insulation material, the pointer cannot be checked and may be distorted.
Factory 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. 5)
Figure 5. Pointer position for shipment
Manually 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. 6, 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.

Auxiliary switch / Auxiliary potentiometer (optional)
IMPORTANT:
•The auxiliary switch/potentiometer is installed on site. Refer to the instructions supplied with the auxiliary
switch/potentiometer for installation.
•Do not open the top cover except when adjusting the auxiliary switch/potentiometer. Close the top cover
instantly after adjusting the auxiliary switch/potentiometer.
•Do not put any load on the top cover.
Procedure 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 put 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. 7>
2) Remove the screws connecting the yoke and the valve. <Step 2 in Fig. 7>
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 fit the yoke into the new mounting position.
5) Before fixing 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, fix the yoke to the valve.
<Step 3 in Fig. 7>
6) Mount the actuator. Place the actuator, with its facing direction changed, on the yoke, and fix them with the screws.
<Step 4 in Fig. 7>
7) Check that the ACTIVAL with the mounting position changed operates smoothly (from 0 % to 100 %).

Wiring
CAUTION
•Disconnect power from ACTIVAL before performing any wiring or maintenance (installation) to prevent equipment
damage.
IMPORTANT:
•The ACTIVAL is designed for 24 V AC power supply voltage.
Do not apply any other power voltage (e.g., 100 V AC, 200 V AC) to the ACTIVAL.
•For 2-10 V DC input type and 4-20 mA input type, make sure the polarity of the power supply and 2-10 V DC
feedback output referring to Figs 13 and 14. Incorrect wiring may result in PCB (print circuit board) burnout.
•To prevent damage, cover the terminals except when connecting/disconnecting wires.
•Do not connect 24 V AC power to the terminals 4 to 7.
Wiring precautions
1) To lead the wires into the terminals, cut out a knockout hole for a wiring port. Two knockout holes are provided on the
bilateral sides of the actuator terminals. Select a knockout hole according to the conduit mounting direction, and cut it out by
lightly knocking the hole using a screwdriver.
Figure 8. Knockout hole for wiring port
2) Unscrew the 3 setscrews (M4 ×10) of the terminal cover and remove the terminal cover, as shown in Fig. 9.
Figure 9. Terminal cover removal
3) Correctly connect the wires to the terminals with M3.5 screw terminal lugs, referring to Figs 10 to 18.
4) When the ACTIVAL is used in a high-humidity environment or outdoors, use a water-proof connector for the wiring port.
To keep IP54 protection (dust-proof and splash-proof),
Use a water-proof connector for the ACTIVAL in a high-humidity environment or outdoor location.
•Be sure to completely close the terminal cover and the top cover.
•Waterproof the wiring port.
- For cable connection, use a water-proof connector. (Seal connector Part No. 83104346-003 is recommended.)

Inspection and Maintenance
CAUTION
•Avoid touching the installed ACTIVAL (valve body, yoke, joint). When being used to control hot water, it reaches
high temperature and may cause burn injury.
•Inspect the ACTIVAL according to Table 1.
•Manually open/close the ACTIVAL at least once a month if it is left in inactive state for a long period.
•Visually inspect the fluid leakage of the valve and the actuator operations every six months. If any of the problems
described in Table 2 are found, take corresponding actions shown in the table.
If your problem is not solved by the corresponding action, please contact Azbil Corporation near you.
Table 1. Inspection items and details
Inspection item Inspection interval Inspection detail
Visual inspection Semiannual •Fluid leakage from the gland and the flange face
•Loosened bolts
•Valve and actuator damages
Operating status Semiannual •Unstable open/close operation
•Abnormal noise and vibration
Routine inspection Any time •Fluid leakage to the outside
•Abnormal noise and vibration
•Unstable open/close operation
•Valve hunting
Table 2. Troubleshooting
Problem Part to check Action
Fluid leaks from the flange face. Loosened flange bolts
Gasket on the flange face
Misaligned piping
Tighten the flange bolts.
Replace the gasket.
Redo piping.
Fluid leaks from the gland part. ⎯Consult with our sales personnel.
Fluid leaks from the bonnet. Loosened bolts Tighten the bolts.
Valve does not operate smoothly /
valve stops halfway /
valve does not operate at all.
Conditions of the power applied and of the input
signal applied
Loosened terminals
Wiring condition / disconnected wires
Check the power supply and the controller
connected to.
Tighten the terminals.
Check the wiring.
Fluid leaks to the outside of the valve
when the ACTIVAL is in fully closed
position.
Actuator pointer not pointing to fully closed
position
Fully close the ACTIVAL.
The valve vibrates or produces an
abnormal noise.
Primary pressure condition
Differential pressure condition
Adjust the mounting position and change the
installation location.
The auxiliary switch does not operate. Auxiliary switch (cam switch) condition
Loosened terminals
Wiring condition / disconnected wires
Redo the cam switch setting.
Tighten the terminals.
Check the wiring.
The auxiliary potentiometer does not
operate.
Condition of resistance
Loosened terminals
Wiring condition / disconnected wires
Check the resistance value (1 kΩ).
Tighten the terminals.
Check the wiring.
Valve hunting occurs. Secondary pressure condition
Differential pressure condition
Control stability
Adjust the mounting position and change the
installation location.
Correct the control parameter setting of
controller.
Voltage/current input signal disagrees
with the feedback output signal.
To completely shut off the valve, valve open and close (0-100% position) operation is controlled by
10-90 % range of actuator voltage/current input signal. Voltage/current input signal therefore
disagrees with the feedback signal, and this is not an error.
