(ANSI Class125 equivalent / Gray cast iron)*



General

ACTIVAL™ Model VY5199J for high differential pressure

application is a series of motorized two-way valves with

flanged-end connection. Rotary valve and actuator are

integrated in a single unit.

Valve size ranges from 11/2” to 6”.

Actuator has a reversible synchronous motor, which

operates at a low voltage of 24 V AC.

4 to 20 mA DC input control signal provides proportional

control in combination with a single loop controller (e.g.,

Model SDC35/SDC36).



Features

•Applicable to high differential pressure applications:

Water ow is controlled inside the valve to prevent over

pressure drop, leading to cavitation erosion resistance.

(See Fig. 1.)

•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.

•Durable actuator with low power consumption

• Modied linear ow characteristics

•Valve applicable to high differential pressure, high Cv

value, wide rangeability, and low leakage

•4 to 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 to 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.

• CE Marking certied:

ACTIVAL Model VY5199J conforms to all the applicable

standards of CE Marking.

* This product was designed and manufactured conforming to the ISO (International Organization for Standardization, PN16/GG-20).

Recommended Criteria to Prevent Cavitation Erosion

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

criterion value.

XF=

XF: Pressure ratio

P1: Absolute pressure of valve inlet [psig (abs)]

P2: Absolute pressure of valve outlet [psig (abs)]

Pv: Saturated vapor pressure of uid* [psig (abs)]

∗ Saturated vapor pressure of uid varies depending on the uid 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.

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

Flow velocity [fps] = 263.5 x d2

Q = Flow rate [GPM]

d = Valve size [DN (mm)]

Always keep the ow velocity < 23.0 fps (7.0 m/s) (criterion value) for chilled water and < 16.4 fps (5.0 m/s) (criterion value)

for hot water.

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

Setting

On the PCB (printed circuit board) of the actuator, the selector switches are provided.

WARNING

•Before wiring, maintenance or setting the selector switches, be sure to turn off the power to the product

(including the optional devices). Failure to do so might cause electric shock or device failure.

•Detach the cover only when wiring, setting the product or maintenance and reattach the cover after wiring,

setting the product or maintenance. Failure to do so might cause electric shock.

CAUTION

a• Set the selector switches using a pen nib or a nger. Do not use a tool such as a screwdriver. Such a tool might

damage the selector switches or the PCB.

•During engineering work, do not touch the uninstructed area other than the setting switches. Doing so, you

might be burned. Temperature of some parts of the actuator will become high.

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.

•To operate the product with small dead band, provide shielded cable for input/output signal lines and power line.

Unshielded cable can cause error due to noise.



Identication of the selector switches

Figure 4. Selector switches

Open/close selector switch for input signal failure:

If no control signal is input, the actuator automatically closes (0 %) or opens (100 %) the valve by setting the selector switch

at ‘open’ (100 %) or ‘close’ (0 %).

Direction selector switch for control action of 4 to 20 mA input signal:

Direction of control action by 4-20 mA DC input signal can be reversely switched.

Normal action: 4 mA for 0 % to 20 mA for 100 %

Reverse action: 20 mA for 0 % to 4 mA for 100 %

Normal/small selector switch for dead band width:

To more precisely operate the valve, smaller dead band (than the normal) of the control signal input can be set. Two selector

switches are provided for the normal/small dead band width. Always set the both switches at the same mode (‘normal’ or

‘small’).

Open/close selector switch

for input signal failure

(Initially set at ‘close’.)

Direction selector switch

for control action of 4-20 mA input signal

(Initially set at normal action

(4mA:0% to 20mA:100%))

Normal/small selector switch

for dead band width

(Initially set at ‘normal’ dead band.)
