Motorized Three-Way Valve
with Flanged-End Connection
(145 psig / Gray cast iron)*
General
ACTIVAL Model VY54X0F is a series of motorized three-way
valves with flanged connection. The valve and the actuator
are integrated in a single unit.
The valve size ranges from 2” to 3”.
The actuator has a reversible synchronous motor, which
operates at a low voltage of 24 V AC.
Control signal is 4 to 20 mA DC input. Executes proportional
control in combination with a single loop controller (e.g.,
Model SDC15).
Features

Valve and actuator integrated in a single unit
NEMA 4X and IP54 enclosure rating
(Waterproof connectors are required to assure NEMA 4X
and IP54)
Valve with large Cv value, high rangeability, and low
leakage
Actuator with low power consumption and Durable
design
Linear flow characteristics
2 to 10 V DC output (for position feedback) available with
4 to 20 mA DC input type
CE Marking certified:
ACTIVAL Model VY54X0F conforms to all the applicable
standards of CE Marking.
* This product was designed and manufactured conforming to the JIS (Japanese Industrial Standards, JIS10K/FC200).

Installation
Precautions for installation
WARNING

Some of the product models weigh more than 40 lb (18.1 kg). Carefully move the product with a vehicle or enough
manpower in an appropriate manner. Careless lift or accidental drop of the product might cause injury or product
damage.
CAUTION
For installation, do not mount the valve in an improper position or overtighten the bolts on the flange. Doing so
might damage the product.
After installation, make sure no fluid leaks from the valve-pipe connections. Incorrect installation might cause fluid
leakage.
Keep the products in package for storage. Failure to do so might damage or stain the products.

Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer (with 40 or more
meshes) on the inflow side of the piping. Flush the piping to remove the foreign objects after installation. Foreign
objects inside the piping might damage the product.
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety
standards.
ACTIVAL Model VY54X0F 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 inflow side of each valve, install it on the pipe diverting sections
(sections diverting from main piping system to sub piping system).
The arrow indicated on the valve body (port A/port B port AB) is the flow direction of the process fluid for mixing use. This
product also can be installed for diverting use (port AB port A/port B).
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.
Do not use the product in an atmosphere corrosive to the actuator, valve, and their components. Doing so might
damage the product.
IMPORTANT:
The top and the terminal 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 6 shows the minimum clearance
for maintenance and inspection.
When installing the ACTIVAL in a ceiling space, provide an access hole within 20" (50.8 cm) radius of the ACTIVAL.
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.

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. 9.) However, the ACTIVAL must be installed always in
upright position outdoors.
Figure 9. Mounting position
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 inflow, outflow, and bypass sides. If difference between the coil side pipe
resistance (which contains coil resistance) and the bypass side pipe resistance are extremely large, use the gate valves to
adjust the pressure. Also, install a strainer with 40 or more meshes on the inflow 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
close, or the valve seat may get damaged causing fluid 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 flow into the valve. Valve cannot fully close, or the valve seat may get damaged causing fluid leakage,
due to the sealing material jammed inside the valve.
Before activating the ACTIVAL, fully open (in 100 % position) the valve and flush the pipes (flush per each port) at the
maximum flow rate to remove all the foreign substances. (Factory preset position: Port A in 100 %)

Heat insulation
Do not apply heat insulation to the actuator or to the yoke, as shows in Fig. 7. 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% (Port A in fully open position) for shipment. The shaft is completely turned clockwise,
and the pointer points at “100”. (See Fig. 11.)
Figure 11. 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 (100)/closed (0) 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. 12, 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.
Figure 12. Manual open/close operation
Auxiliary switch (optional)
The auxiliary switch is installed on site. Refer to the instructions supplied with the auxiliary switch for installation.
IMPORTANT:
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.
