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.

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.

AB-7356-U

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 %)

Identify ports A and B with the letters ‘A’ and ‘B’ marked on the valve body.

Valve body with heat insulation wrapped:

Identify ports A and B with the raised bar shape on the valve bonnet, as

shown in Fig. 8.

AB-7356-U

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.
