ACTIVAL™
Motorized Two-Way Valve with Flanged-End Connection
(Spring Return Type Actuator)
<4-20 mA DC Input with 4-20 mA DC Feedback Output>
(JIS 10K-FC200, -SCS13A)
Overview
ACTIVAL model VY519XH/VY519XK is a series
of motorized two-way valves with flanged-end
connection. The 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 JIS 10K.
The actuator has a reversible synchronous motor,
which operates at a low voltage of 24 V AC. Since
the actuator fully closes the valve in case of power
failure, it is suitable for failsafe application.
4-20 mA DC input control signal provides proportional
control in combination with a PLC (e.g., Model R35/R36).
* JIS: Japanese Industrial Standards
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.
•Dust- and splash-proof structure (IEC IP54)
Installable in an AHU.
Note: Waterproof connectors are required to ensure IP54.
•Valve for water/steam control applicable to high
di󰀨erential 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.
•Spring return actuator:
Actuator automatically closes the valve in 0 % position
in case that the power is down.
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.
•Use shielded cable for the ACTIVAL
with small dead band. Noise may
affect the signal transmission
causing operation error, otherwise.
•To control ACTIVAL with a third-party
controller, please consult with Azbil
Corporation’s sales personnel.

Safety Precautions
Please read instructions carefully and use the product
as specified in this manual. Be sure to keep this
manual near by for ready reference.
Restrictions on Use
This product was developed, designed, and
manufactured for general air conditioning use.
Do not use the product in a situation where human
life may be at risk or for nuclear applications in
radiation controlled areas. If you wish to use the
product in a radiation controlled area, please
contact Azbil Corporation.
Particularly when the product is used in the
following applications where safety is required,
implementation of fail-safe design, redundant
design, regular maintenance, etc., should be
considered in order to use the product safely and
reliably.
•Safety devices for protecting the human body
•Start/stop control devices for transportation
machines
•Aeronautical/aerospace machines
For system design, application design, instructions
for use, or product applications, please contact
Azbil Corporation.
Azbil Corporation bears no responsibility for any
result, or lack of result, deriving from the customer's
use of the product.
Recommended Design Life
It is recommended that this product be used within
the recommended design life.
The recommended design life is the period during
which you can use the product safely and reliably
based on the design specications.
If the product is used beyond this period, its failure
ratio may increase due to time-related deterioration
of parts, etc.
The recommended design life during which the
product can operate reliably with the lowest
failure ratio and least deterioration over time is
estimated scientically based on acceleration tests,
endurance tests, etc., taking into consideration the
operating environment, conditions, and frequency
of use as basic parameters.
The recommended design life of this product is 10
years.
The recommended design life assumes that
maintenance, such as replacement of the limited
life parts, is carried out properly.
Refer to the section on maintenance in this manual.

handling may cause minor injury
or material loss.
Symbols

Notifies users that specific actions are
prohibited to prevent possible danger. The
symbol inside graphically indicates the
prohibited action.
(For example, the sign on the left noties
that disassembly is prohibited.)

Instructs users to carry out a specific
obligatory action to prevent possible
danger. The symbol inside graphically
indicates the actual action to be carried out.
(For example, the sign on the left indicates
general instructions.)
WARNING

When handling or transporting any heavy
product (more than 18 kg), carefully move
the product with a hand truck or the like, or
with 2 or more people.
Careless lifting or accidental dropping of
the product may result in injury or product
damage.

Before removing the actuator, fully close
the valve.
If you try to remove the actuator without
fully closing the valve, the actuator may
suddenly rotate and cause an injury.
Do not disassemble the spring unit.
The spring may fly out of the unit and
cause an injury.
CAUTION
Provide a circuit protector (e.g., a fuse or
circuit breaker) for the power source.
Failure to do so may cause a short circuit
leading to re or device failure
Do not freeze this product.
Doing so may damage the valve body and
cause leakage.
When piping this product, be sure there is
no foreign matter in the pipes.
If foreign matter remains in the pipes, the
product may break down.

CAUTION
Install, wire, and use this product under
the conditions specied by this manual.
Failure to do so may cause re or device
failure.
Use full face gaskets for at face anges.
Failure to do so may damage the anges
or cause leakage outside of the valve.

When installing this product, hold it in the
