Recommended Criteria to Prevent Cavitation Erosion

Cavitation erosion is likely to occur in the case that the pressure ratio XFcalculated by the following formula overreaches the

criterion value.

F: Pressure ratio

1: Absolute pressure of valve inlet [kPa (abs)]

2: Absolute pressure of valve outlet [kPa (abs)]

Pv: Saturated vapor pressure of fluid* [kPa (abs)]

* Saturated vapor pressure of fluid varies depending on the fluid temperature.

Always keep the pressure ratio XF< 0.7 (criterion value).

If the pressure ratio does not meet this criterion, cavitation erosion may occur. This value is thus necessary to prevent cavitation

erosion. Note that cavitation itself may be generated even if the pressure ratio is kept below 0.7.

In addition to the pressure ratio, the flow velocity at the valve in 100 % position is another criterion for cavitation erosion.

Flow velocity [m/s] = 21.22 ×

Q = Flow rate [liter/min]

d = Valve size [DN (mm)]

Always keep the flow velocity < 7.0 m/s (criterion value) for chilled water and < 5.0 m/s (criterion value) for hot water.

If the flow velocity does not meet these criteria, cavitation erosion may occur.

Installation

Precautions for installation

CAUTION

•Disconnect power from ACTIVAL before performing any wiring or maintenance (installation) to prevent equipment

damage.

•Install the ACTIVAL in the position as specified in this manual. Excessively tight connection of the valve to a pipe

and improper installation position may damage the valve.

•After installation, make sure no fluid leaks from the connecting parts of valve and pipes. Incorrect piping may

cause fluid leakage.

•Do not allow any foreign substance inside the piping. Flush the piping so that no foreign substance remains.

Foreign substance can damage the valve.

•ACTIVAL Model VY51XXJ0 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).

•Install the valve so that the flow direction of process fluid agrees with the arrow indicated on the valve body.

•After installation, remove buffer material wrapped around the valve (DN100 to DN150 model).

Installation location

CAUTION

•Avoid using the ACTIVAL in an atmosphere containing oxidizing or explosive gas since it may corrode the actuator,

valve, or their components.

•The actuator may malfunction if being exposed to high temperature radiation. Do not install it near by steam coil or

hot water (high temperature) coil.

IMPORTANT:

•The 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.

•

lthough 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. Figs 2 to 4 show 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.

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. 6.) However, the ACTIVAL must be installed always in

upright position outdoors.

Correct mounting Incorrect mounting

Figure 6. ACTIVAL mounting positions

AB-6763

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 on the inflow side.

•Before activating the ACTIVAL, fully open (in 100 % position) the valve and flush the pipes at the maximum flow rate to

remove all the foreign substances. (Factory preset position: 100 %)

Heat insulation

Do not apply heat insulation to the actuator or to the yoke, as shows in Fig. 5. 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. 7.)

Figure 7. Preset 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/closed 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. 8, 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.
