(PN16 / GG-20)
General
ACTIVALTM Model VY519XJ is a series of motorized two-
way valves with anged-end connection. Rotary valve and
actuator are integrated in a single unit.
Valve size ranges from DN15 (1/2”) to DN80 (3”), 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
• 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.
• Valve for chilled/hot water control and for steam control
applicable to high differential pressure, large Cv value,
high rangeability, and low leakage.
• Durable actuator with low power consumption.
• Equal percentage ow characteristics.
• 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 product.

Identication of the selector switches
Figure 3. 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• Installation and wiring must be performed by qualified personnel in accordance with all applicable safety
standards.
a• Install the product 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.
Attach a strainer in a pipe on the in ow side of the product to prevent equipment damage.
a• Disconnect power from the product (including the optional devices) before performing any wiring, maintenance,
or setting the selector switches to prevent equipment damage.
• ACTIVAL Model VY519XJ 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 (with 80 or more meshes
recommended for steam control) on the in ow 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.
Installation location
ACAUTION
a• Avoid using the product in an atmosphere containing oxidizing gas, explosive gas, etc. since it may damage the
actuator, valve, or their components.
a• Do not install the product nearby a steam coil or a hot-water (in high temperature) coil. High heat radiation may
result in an actuator malfunction.
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.
• To set the selector switches after installation, leave a enough clearance above the top cover of the actuator, as shown in
Fig. 1.
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 inow, outow, and bypass sides. Also, install a strainer with 40 or more
meshes (with 80 or more meshes recommended for steam control) on the inow 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.
Heat 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.
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 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 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. 7>
6) Mount the actuator. Place the actuator, with its facing direction changed, on the yoke, and x 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 %).

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.
• Make sure the polarity of the power supply and 4-20 mA DC feedback output referring to the wiring diagrams.
Incorrect wiring may 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.
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 12.

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 W.
* 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. 11 and 12 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
S• Avoid touching the installed product (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
Table 2. Troubleshooting
Problem Part to check Action
Fluid leaks from the ange face. Loosened ange bolts
Gasket on the ange face
Misaligned piping
Tighten the ange 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 kW).
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.
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.
