Motorized Two-Way Valve with Flanged-End Connection
for High Differential Pressure Application
<4-20 mA DC Input with 4-20 mA DC Feedback Output>
(PN16 / GG-20)
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 DN15 (1/2”) to DN150 (6”), and
valve body rating corresponds to ISO PN16.
Actuator has a reversible synchronous motor, which
operates at a low voltage of 24 V AC.
4-20 mA DC input control signal provides proportional
control in combination with a PLC (e.g., Model R35/R36).
∗PLC: Programmable Logic Controller
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
•4-20 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 4-20 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 VY51 conforms to all the applicable
standards of CE Marking.
∗Although our company name changed from Yamatake Corporation to Azbil Corporation on April 1, 2012, our former logo remains on this

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 [kPa (abs)]
P2: Absolute pressure of valve outlet [kPa (abs)]
Pv: Saturated vapor pressure of uid* [kPa (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.
In addition to the pressure ratio, the ow velocity at the valve in 100 % position is another criterion for cavitation erosion.
Flow velocity [m/s] = 21.22 ×
Q = Flow rate [liter/min]
d = Valve size [DN (mm)]
Always keep the flow velocity < 7.0 m/s (criterion value) for chilled water and < 5.0 m/s (criterion value) for hot water.
If the ow velocity does not meet these criteria, cavitation erosion may occur.

Setting
On the PCB (printed circuit board) of the actuator, the selector switches are provided.
ACAUTION
a•Disconnect power from the product (including the optional devices) before performing any wiring, maintenance,
or setting the selector switches to prevent equipment damage.
a•Always close the top cover and the terminal cover except when setting the selector switches and connecting/
disconnecting wires.
a• Set the selector switches using a pen nib or a nger. Do not use a tool such as a screwdriver. Such a tool can
damage the selector switches or the PCB.
a•To operate the product with small dead band, provide shielded cable for input/output signal lines and power line.
Unshielded cable can cause error due to noise.
IMPORTANT:
The service life of ACTIVAL operated with small dead band can be shortened since the ACTIVAL operates
more frequently with small dead band than with normal dead band.
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 4-20 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
switches are provided for the normal/small dead band width. Always set the both switches at the same mode (‘normal’ or
‘small’).

Installation
Precautions for installation
ACAUTION
a•Disconnect power from ACTIVAL before performing any wiring, maintenance (installation), and setting the
selector switches to prevent equipment damage.
a•Install the ACTIVAL in the position as specified in this manual. Excessively tight connection of piping and
improper installation position may damage the valve.
a• After piping installation, make sure no uid leaks from the connecting parts. Incorrect piping may cause uid
leakage.
a•Do not allow any foreign substance inside the piping. Flush the piping so that no foreign substance remains.
Foreign substance can damage the valve.
•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 (DN100 to DN150 model).
Installation location
ACAUTION
a•Avoid using the ACTIVAL in an atmosphere containing oxidizing or explosive gas since it may corrode the
actuator, valve, or their components.
a•The actuator may malfunction if being exposed to high temperature radiation. Do not install it near by steam
coil or hot water (high temperature) 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.
•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 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.
•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.

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 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 may 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 may
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 / 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 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 %).

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.)
- For conduit connection, use a water-proof plica tube or the like.

Connection Examples (Connection to Azbil Corporations’ R series controller)
Connection to Model R35TC0/R36TC0 Connection to Model R35TC0/R36TC0 (Parallel operation)
Notes:
∗Input impedance of the actuator is 100 Ω.
∗For connecting multiple ACTIVAL to one controller (e.g., Model R35.36), provide a transformer (two in total) for each ACTIVAL
since 4-20 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. (R series controllers including Model R35/R36 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.

Inspection and Maintenance
ACAUTION
a•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 uid 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 ange 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

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. Input signal therefore disagrees with
the feedback signal, and this is not an error.
