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

Install the product so that no foreign objects remains inside the pipes. Be sure to provide a strainer 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.

Keep the products in package for storage. Failure to do so might damage or stain the products.

Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
IMPORTANT:
When installing the product with a flange gasket, do not allow the gasket going inside the pipe.
Precautions for installation
ACTIVAL Model VY51XEJ 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. If
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).
Install the valve so that the flow direction of process fluid agrees with the arrow indicated on the valve body.
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 chemicals and organic solvent or their vapor. Do not
expose the ACTIVAL to such substances/vapor.
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 actuator 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 20" (508 mm) 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.
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. 3.) 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 inflow, outflow, and bypass sides. Also, install a strainer with 40 or more
meshes on the inflow 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 closes, or the valve seat might 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 closes, or the valve seat might 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 (with the ACTIVAL installed) at
the maximum flow rate to remove all the foreign objects. (Factory preset position: 100 %)
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. 4.)
Figure 4. Pointer position for shipment
Manually opening/closing the ACTIVAL
IMPORTANT:
Before manually open/close the ACTIVAL, turn off the power (24 V AC). Failure to do so might damage the
actuator.
To manually open/close the ACTIVAL, do not turn the joint beyond the fully open (100)/closed (0) mark.
Disconnect the power from the ACTIVAL before manually operating the ACTIVAL. As shown in Fig. 5, 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 (optional)
The auxiliary switch is installed on site. Refer to the instructions supplied with the auxiliary switch/potentiometer for installation.
IMPORTANT:
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.
When changing the mounting position, set the ACTIVAL (actuator and valve) in 100 % position. If the valve and
actuator are assembled in a wrong positon, position of valve and actuator do not match, the actuator's gears
will be damaged because the actuator tries to actuate the valve although it in in fully open or fully closed state.
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. 6>
2) Remove the screws connecting the yoke and the valve. <Step 2 in Fig. 6>
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 fit the yoke into the new mounting position.
5) Before fixing 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, fix the yoke to the valve.
<Step 3 in Fig. 6>
6) Mount the actuator. Place the actuator, with its facing direction changed, on the yoke, and fix them with the screws.
<Step 4 in Fig. 6>
7) Check that the ACTIVAL with the mounting position changed operates smoothly (from 0 % to 100 %).
