Recommended Criteria to Prevent Cavitation Erosion
Cavitation erosion is likely to occur in the case that the pressure ratio XF calculated by the following formula overreaches the
criterion value.

Pv: Saturated vapor pressure of uid* [psig (abs)]
Saturated vapor pressure of uid varies depending on the uid temperature.
∗
Always keep the pressure ratio X
< 0.7 (criterion value).
F
If the pressure ratio does not meet this criterion, cavitation erosion may occur. This value is thus necessary to prevent
cavitation erosion. Note that cavitation itself may be generated even if the pressure ratio is kept below 0.7.
IIn addition to the pressure ratio, the ow velocity at the valve in 100 % position is another criterion for cavitation erosion.
Flow velocity [fps] = 263.5 x
Q

d
Q = Flow rate [GPM] d = Valve size [DN (mm)]
Always keep the ow velocity < 23.0 fps (7.0 m/s) (criterion value) for chilled water and < 16.4 fps (5.0 m/s) (criterion value)
for hot water.
If the ow velocity does not meet these criteria, cavitation erosion may occur.

a
a
ACTIVAL Model VY5199J 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 40 or more meshes) on the inflow side of each
•
valve. In case that the strainers cannot be installed on the inow 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 ow direction of process uid agrees with the arrow indicated on the valve body.
•
After installation, remove buffer material wrapped around the valve (4'' to 6'' model).
•
(including the optional devices). Failure to do so might cause electric shock or device failure.
CAUTION
After installation, make sure no uid leaks from the valve-pipe connections. Incorrect installation might cause
•
uid leakage.
For installation, do not mount the valve in an improper position or overtighten the bolts on the ange. Doing so
•
might damage the product.
Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer on the inow
•
side of the piping. Flush the piping to remove the foreign objects after installation. Foreign objects inside the
piping.
Installation location
CAUTION
Do not install the product nearby a steam coil, pressurized hot-water coil, or any high heat source.
•
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.
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. Fig. 2 shows the minimum
•
clearance for maintenance and inspection. When installing the ACTIVAL in a ceiling space, provide an access hole within
the 20" (508 mm) 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.
•
To set the selector switches after installation, leave a enough clearance above the top cover of the actuator, as shown in
•
Figs. 2 to 4.
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. 5.) However, the ACTIVAL must be installed always in
upright position outdoors.
High temperature radiation might cause malfunction of its actuator.

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 inow, outow, and bypass sides. Also, install a strainer on the inow side.
•
When installing the ACTIVAL to pipes, do not allow any object, such as chips, to get inside a pipe or valve. Valve cannot
•
fully closes, 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 at the maximum ow rate to
•
remove all the foreign substances. (Factory preset position: 100 %)
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
counterclockwise, and the pointer points at ‘100’. (See Fig. 6.)

installation.
Do not open the top cover except when adjusting the auxiliary switch. Close the top cover instantly after
•
adjusting the auxiliary switch.
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 before 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 get 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. 8>
2) Remove the screws connecting the yoke and the valve. <Step 2 in Fig. 8>
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. 8>
6) Mount the actuator. Place the actuator, with its facing direction changed, on the yoke, and x with the screws. <Step 4 in
Fig. 8>
7) Check that the ACTIVAL with the mounting position changed operates smoothly (from 0 % to 100 %).

- For cable connection, use a water-proof connector. (Seal connector Part No. 83104346-003 is recommended.)
- For conduit connection, use a water-proof plica tube or the like.
Wiring procedure
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.

Notes:
Input impedance of the actuator is 100 Ω.
∗
For connecting multiple ACTIVAL to one controller (e.g., Model SDC35/SDC36), provide a transformer (two in total) for each ACTIVAL
∗
since 4 to 20 mA input is not isolated from other terminals.
Terminals 2, 5, and 7 are connected inside the actuator. To connect to a device (PLC, position indicator, etc.) with its terminals not isolated
∗
inside, externally isolate (between the ACTIVAL and the device). Otherwise, a loop is formed for the common line and can damage the
circuit of the ACTIVAL. (SDC series controllers including Model SDC35/SDC36 shown in Figs. 12 and 13 are isolated inside.)
Isolation transformer is required for ACTIVAL. Transformer without isolation may damage the ACTIVAL and other devices connected to

ACTIVAL.

Control stability
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. Input signal therefore disagrees with
the feedback signal, and this is not an error.
Tighten the ange bolts.
Replace the gasket.
Redo piping.
Consult with our sales personnel.
