General
ACTIVAL™ Model VY5199J for high differential pressure
application is a series of motorized two-way valves with
flanged-end connection. Rotary valve and actuator are
integrated in a single unit.
Valve size ranges from 11/2” to 6”.
Actuator has a reversible synchronous motor, which
operates at a low voltage of 24 V AC.
4 to 20 mA DC input control signal provides proportional
control in combination with a single loop controller (e.g.,
Model SDC35/SDC36).

Features
•Applicable to high differential pressure applications:
Water ow is controlled inside the valve to prevent over
pressure drop, leading to cavitation erosion resistance.
(See Fig. 1.)
•Compact and lightweight:
Rotary motor actualizes small body and light weight.
•Valve and actuator integrated in a single unit:
Pre-assembled body requires no adjustment.
•Durable actuator with low power consumption
• Modied linear ow characteristics
•Valve applicable to high differential pressure, high Cv
value, wide rangeability, and low leakage
•4 to 20 mA DC output available for position feedback.
•Open/close changeover for input signal failure:
Actuator fully opens/closes valve in case that the control
signal is not input to the actuator. (Default: Fully open)
•Direction changeover of control action:
Open/close action by 4 to 20 mA DC input signal is
reversely controllable.
Normal action 4 mA: 0 % to 20 mA: 100 %
Reverse action 20 mA: 0 % to 4 mA: 100 %.
(Default: Normal action)
•Adjustable dead band*:
Dead band width can be narrowed to more precisely
operate valve actuator.
∗Actuator is not operated by input signal changed less than a
certain amount. This amount of change is called dead band.
• CE Marking certied:
ACTIVAL Model VY5199J conforms to all the applicable
standards of CE Marking.

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.
XF=
XF: Pressure ratio
P1: Absolute pressure of valve inlet [psig (abs)]
P2: Absolute pressure of valve outlet [psig (abs)]
Pv: Saturated vapor pressure of uid* [psig (abs)]
∗ Saturated vapor pressure of uid varies depending on the uid temperature.

Always keep the pressure ratio XF< 0.7 (criterion value).
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 d2
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.

Identication of the selector switches
Figure 4. Selector switches
Open/close selector switch for input signal failure:
If no control signal is input, the actuator automatically closes (0 %) or opens (100 %) the valve by setting the selector switch
at ‘open’ (100 %) or ‘close’ (0 %).
Direction selector switch for control action of 4 to 20 mA input signal:
Direction of control action by 4-20 mA DC input signal can be reversely switched.
Normal action: 4 mA for 0 % to 20 mA for 100 %
Reverse action: 20 mA for 0 % to 4 mA for 100 %
Normal/small selector switch for dead band width:
To more precisely operate the valve, smaller dead band (than the normal) of the control signal input can be set. Two selector

Precautions for installation
WARNING
•Before wiring, maintenance or setting the selector switches, be sure to turn off the power to the product
(including the optional devices). Failure to do so might cause electric shock or device failure.
CAUTION
a• 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.
a• Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer on the inow
side of the piping. Flush the piping to remove the foreign objects after installation. Foreign objects inside the
piping.
•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 inow 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).

Installation location
CAUTION
•Do not install the product nearby a steam coil, pressurized hot-water coil, or any high heat source.
High temperature radiation might cause malfunction of its actuator.
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

• Install a bypass pipe and gate valves on the inow, outow, and bypass sides. Also, install a strainer on the inow 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.)
Figure 6. Preset pointer position for shipment

Manually opening/closing the ACTIVAL
IMPORTANT:
•Manually opening/closing the ACTIVAL with the power (24 V AC) applied might damage the actuator.
•To manually open/close the ACTIVAL, do not turn the joint beyond the fully open/closed mark.
•To manually open/close the ACTIVAL, slowly turn the joint. If shock is sent to the actuator, the actuator might
get damaged.
Disconnect the power from the ACTIVAL before manually operating the ACTIVAL. As shown in Fig. 7, 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 (optional)
IMPORTANT:
•The auxiliary switch is installed on site. Refer to the instructions supplied with the auxiliary switch for
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 %).

Wiring
WARNING
•Before wiring, maintenance or setting the selector switches, be sure to turn off the power to the product
(including the optional devices). Failure to do so might cause electric shock or device failure.
•Detach the cover only when wiring, setting the product or maintenance and reattach the cover after wiring,
setting the product or maintenance. Failure to do so might cause electric shock.
CAUTION
a•Installation and wiring must be performed by qualified personnel in accordance with all applicable safety
standards.
IMPORTANT:
•The ACTIVAL is designed for 24 V AC power supply voltage.
Do not apply any other power voltage (e.g., 120 V AC, 240 V AC) to the ACTIVAL.
•Make sure the polarity of the power supply and 4 to 20 mA DC feedback output referring to the wiring
diagrams. Incorrect wiring might result in PCB (print circuit board) burnout.
•To prevent damage, cover the terminals except when connecting/disconnecting wires.
•Do not leave any refuse including metal chips after cutting a knockout hole and after connecting the wires
inside the actuator.
•Do not connect 24 V AC power to the terminals 4 to 7.

To keep NEMA 4X and IP54 protection
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.)
- 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.

Connection to Model SDC35TC0/SDC36TC0 Connection to Model SDC35TC0/SDC36TC0 (Parallel operation)
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.
