Valve Installation
Before installing the valve, ensure that the hydraulic connections follow the
fluid directions as shown in the provided diagram. Make sure the pipes are
clean and free from weld slag to prevent damage to the internal parts of the
valve.
Q: What should I do if I notice irregular leakage from the valve?
A: In case of irregular leakage, check and replace O-rings and stem packing as
necessary.
Q: Can the product specifications change without notice?
A: Yes, the performances stated in the product sheet can be modified without
any prior notice.
Smart Balancing Control Valve
VALVE INSTALLATION
Hydraulic Connections:
Follow the fluid directions as shown in the diagram below.
Before installing the valve, make sure the pipes are clean and free from weld slag in order not to damage the internal parts of the valve itself.
Before the valve start-up, check if the flow correspond to the indication
printed on the valve body.
The valve has the following specification according to stem position:
- Stem down = fluid passing
- Stem up = fluid intercepted
OPERATING CONDITIONS
Temperature, nominal pressure and differential pressure on the valve must be within the values specified in data sheets EBV_DBL603en.
PIPE FLUSHING
An anomalous valve leackage is caused, in almost all cases, by weld slag or
foreign bodies entrapped between the valve seat and the plug, often causing
damages.
To prevent such inconveniences, it is advisable to use filters upstream of the
valve.
Moreover, the pipelines must be properly washed positioning the valve stem at
half stroke; this operation must be performed before start-up and after a
prolonged shutdown of the system.
The performances stated in this sheet can be modifi ed without any prior notice.
VALVE MAINTENANCE
Valves are equipped with a stuffing box with a double Oring and, therefore, they do not require any particular maintenance. In case of irregular leakage, O-Rings and stem packing have to be replaced.
PRESSURE SENSORS INSTALLATION
Make sure that the fluid is not present in the system and remove the closing caps on the valve flanges. Insert the MF extension and pressure transducers as indicated in the figure below.
ACTUATOR INSTALLATION
The actuators must not be installed in explosive atmosphere and must not be subjected to steam jets of water or dripping. Leave a space above the actuator sufficient to allow the uncoupling of the actuator from the valve body for any maintenance, at least 10-15 cm.
WIRING CONNECTION
Remove the cover screw with a screwdriver and then remove the cover as shown in the picture beside. The actuator is equipped with 3 removable terminal blocks:
- a removable 8-pole terminal block (T1) with power supply, analog and digital command signal and feedback signal;
- a removable 6-pole terminal block (T2) dedicated to the RS-485 bus connection (Modbus);
- a removable 6-pole terminal block (T3) dedicated to the connections of the temperature sensors (only 4 poles are used).

Modulanting Control & Modbus Supervisory
Note: To avoid damages to electronic components caused by the PCB bending, do
not press too much while fixing the terminal block.
Each pole of the terminal blocks is clearly marked and the same label is on
the electronic board.
Before turning on the actuator make sure that the terminal blocks are
correctly connected to the board and that the labels on the terminals and
board match.
CABLE GLAND
The actuator is supplied with 2 cable glands with punched mem-branes for safe and tidy wiring.
- Cable gland 1 for 3 cables: 2-wire cable for power supply; 5- wire cable for control and feedback signals and 3-wire cable for Modbus;
- Cable gland 2 for 4 cables: 2 cables with 2 wires for tempera-ture sensors (if present) and 2 cables with 3 wires for pressu-re trasmitters.

DIAGNOSTIC – ALARM FUNCTIONS
DIAGNOSTIC – ALARM FUNCTIONS
N°| Error type| Actuator status| Actuator behavior| LEDs notification| Possible anomaly| Restore procedure
1
| Stroke less than 5 mm| Calibration / first installation| The actuator
returns to its initial position and does not respond to the command. The
actuator keeps the previous stroke or the default stroke| READ ON| alve with
stroke less than 5 mm| Remove power and re-power again
Stroke greater than 60 mm| Calibration / first installation| The actuator
leaves the ma ximum range of 60mm and moves to the new extreme. Once the new
stroke limit is reached, it returns to the initial position signaling an
anomaly.
The actuator does not learn the new stroke.
| RED fast blinking + GREEN ON| Valve with stroke greater than 60 mm or incorrect coupling| Remove power and re-power again
2
| Unexpected collision within the stroke| Normal operation| The actuator checks the stall condition 5 times. At the end of the attempts it signals an ano- maly. The actuator does NOT learn the new stroke, but after 60s repeats the attempts to check the blocking conditions.| RED fast blinking| Valve blocked| Reverse the con trol signal
3
| Stroke greater than expected| Normal operation| The actuator moves to the new crash position with low spe- ed signaling an anomaly. The actuator does NOT learn the
new stroke.
| RED fast blinking| damaged valve or incorrect coupling| Reverse the con- trol signal
4
| Low supply voltage| Normal operation| The actuator continues to operate but performance is not guaranteed. If the low voltage events persist (events greater than 10), the actuator stops working.| RED blinking alter- nately fast (5sec) and slow (5sec) + GREEN ON| 1. Wrong sizing of transformer| Check and restore power
2. Unstable power supply
5| High supply voltage|
Normal operation
| The actuator continues to operate but performance is not guaranteed. If the high voltage events persist (events greater than 10), the actuator stops working.|
RED slow blinking
| 1. Wrong sizing of transformer| Check and restore power
2. Unstable power supply
6
| temperature sensors error| Normal operation| Temperature or ΔT regulation loops not working.| RED blinking alter- nately fast (5sec) and slow (5sec) + GREEN ON| 1. Incorrect tem perature probe
connection
|
Check the connection and the condition of the temperature sensor
2. Temperature probes damaged
3. Temperature detected outside the range of use
7
| Pressure sensors error|
Normal operation
| Pressure or ΔP regulation Loops not working| Pressure detected outside the range of use or probes damaged
STANDARD LEDs BEHAVIOUR
| N° | LED 1 and LED 2 | Actuator status |
|---|---|---|
| 1 | FIXED GREEN | Actuator has arrived at the extreme end of the calibration |
stroke
2| GREEN SLOW BLINKING| Actuator has arrived or is moving towards an
intermediate point of the calibration stroke
3| RED and GREEN BLINKING AL- TERNATIVELY| Actuator is calibrating the stroke
or performing the initial positioning
4| RED and GREEN FIXED| Manual control activated, the actuator ignores the
control signal. WARNING!
The board is powered
| N° | LED 7 (RED) and LED 8 (RED) | Actuator status |
