Overview
Designed for maximum efficiency in tight spaces, the i-Vu Smart Valves set new design and performance standards for both pressure dependent and pressure independent zoning applications.
Pressure dependent valve The pressure dependent valve is equipped with a space-saving 2-way or 3-way ball valve and an electronic rotary actuator. The valves installation height is 4.33 inches (110 mm) and has the following features:
Ball valve design with zero leakage, which eliminates energy loss
Self-cleaning ball valve technology providing superior clog resistance
Low power consumption up to 95% less than conventional valves
Field-adjustable Cv value to meet your design requirements
Pressure independent valve The pressure independent valve combines a differential pressure regulator
with a 2-way control valve to supply a specific flow for each degree of ball
opening, regardless of system pressure fluctuations. The valve performs the
function of a balancing valve and control valve in one unit, as well as:
Smallest pressure independent characterized ball valve in the market
Actuator runs at 0.3 W, saving energy and transformer power
Flow is adjustable at the actuator and always balanced
Permits installation in tight spaces

Features
Act Net Port
Connects to the Act Net port of the controller for fast and easy communication.
Compact Design
The valves compact design helps maximize workable space.
Ball Valve Technology
Unlike short stroke globe valves with plug and seat design, the self-cleaning ball helps minimize
energy losses caused by clogging (0% A to AB leakage) and eliminates seat leakage. The pressure
dependent valve allows for bi-directional flow, unlike traditional paddle style valves.
Actuator with Patented Brushless DC Motor
The brushless DC motors power consumption, (CQK (Fail Last Position) 2.5 W running, 0.5 W
holding and CQ (Fail-Safe) 0.6 W running, 0.4 W when holding, saves energy and transformer
power. In addition to reducing energy costs, this helps eliminate failures due to stalled motors and
prolongs actuator life. It also allows for more units to be powered by a single transformer.
Snap Fit
The valves connect to the actuator, enabling operators and technicians to install valves quickly,
easily, and without additional tools. This helps simplify commissioning.
Stem Extension for Insulation Unlike conventional valve actuators, which are normally covered by pipe insulation, the stem extension allows easy actuator removal, without damaging the surrounding insulation, helping simplify operation and maintenance activities.

Installing the valve and actuator
To remove the actuator
WARNING Pull straight up. Do not twist to remove.
WARNING Pressure dependent and pressure independent valve assemblies can be installed in a vertical or horizontal
arrangement, as long as the actuator is positioned to avoid water from dripping on the actuator.
10
Flow patterns
Pressure dependent flow pattern
Pressure dependent 2-way valves can be piped with flow
entering and exiting either port.
For on/off control of coil flow, the pressure dependent 3-
way valve is piped with supply entering the bottom part.
For a pressure dependent 3-way switching application, pipe
hot and cold, supply water to either side port and the
appropriate seasonal supply water will exit the bottom port
for regulation by another 2-way valve; typically installed in
the return pipe.
Pressure independent flow pattern
The pressure independent valve consists of a differential
pressure regulator and a control valve. The control valve is
throttled to match the flow command of the control signal. The
differential pressure regulator holds the pressure drop across
the ball of the valve. As system pressure changes, the
differential pressure regulator moves in response to keep the
flow stable. Pressure (P1) at the inlet pressure independent
valve is high and pressure (P3) at the outlet is low.
The differential pressure between (P1) and (P3) must be
between 5 and 50 psi to achieve pressure independent flow.
When differential pressure increases, the regulator opening is
decreased. When differential pressure decreases, the
regulator opening is increased. This allows for the constant
pressure differential across the ball of the valve.
11
Piping Diagrams
Pressure dependent valves - typical piping
12
Pressure independent valves - typical piping
We recommend that you install pressure independent valves on the return side of the coil. This diagram represents a typical
application. Consult engineering specification and drawings for project details. PT ports are recommended, if not supplied on
either side of the valve and the supply side of the heat transfer device, to allow for pressure/flow measurement/calculation.
WARNING Pressure independent valves should be installed with flow in the direction of the arrow on the valve body. If
installed backwards, there could be damage to either the diaphragm or the regulator. The valve assembly can be installed in a
vertical or horizontal arrangement.
13
Installing the actuator
WARNING Do not place a heavy weight on the actuator.
Attach the actuator to the valve body. Align the actuator guide pins to the valve bonnet openings and press down until you hear
a click. To remove the actuator, grasp it with your hand and pull it away from the valve body.
14
Insulation
Insulation should wrap the pipe and valve body but not the actuator. For chilled water applications, use the stem extension
accessory to raise the actuator above the valve body to provide space for insulation.
15
Wiring the actuator to the Act Net port
Wire the actuator cable to the controllers Act Net port.
NOTE Use an 18 AWG, or larger, wire with a maximum length of 300 feet (91.4 meters).

Setting up the i-Vu Smart Valves in the i-Vu application
Your control program must have one BACnet Analog Output (BAO) microblock to set the position and one BACnet Analog Input
(BAI) microblock to get the actual position. If you use multiple valves, each valve needs one BAO and one BAI.
To set the valves position
Using the i-Vu application
1. In the i-Vu interface, on the Properties page > I/O Points tab, locate the BAO that will control the valves position.
2. Select Special in the I/O Type drop-down list.
3. Set the Exp to 00.
4. Set the Num to 102 for a valve with address 4 (Reheat Valve1) and 103 for a valve with address 5 (Reheat Valve2).
To get the valves position
Using the i-Vu application
1. In the i-Vu interface, on the control programs Properties page > I/O Points tab, locate the BAI that will control the valves
position.
2. Select Special from the I/O Type drop-down list.
3. Set the Exp to 00.
4. Set the Num to 102 for a valve with address 4 (Reheat Valve1) and 103 for a valve with address 5 (Reheat Valve-2).
17
Verify communications with the i-Vu Smart Valves
In the i-Vu interface, all the devices connected to the controller are listed on the control programs Driver > Act Net Network
Details. > Properties tab > Act Net Statistics section.
NOTE The controller only detects devices on the Act Net when powered up. If an i-Vu Smart Valve (reheat valve) is
not detected, remove, and then re-apply power to the controller.
18
To set the valves address on the Act Net network
i-Vu Smart Valves come pre-addressed from the factory.
If you need to change the address, do the following:
1. In the i-Vu navigation tree, select the control program.
2. Go to Driver > Act Net Network Details > Properties tab > Act Net Address Setting section.
3. Enter the serial number, which is located on the actuator, in the Serial Number fields.
4. Select Reheat Valve-1 or Reheat Valve-2 from the Device drop-down list.
NOTE Reheat Valve-1 sets to address 4 and Reheat Valve-2 sets to address 5.
5. Click Accept. When the changes are applied, the Operation Status of the Act Net Address Setting table
displays Success.
See the Troubleshooting section in this document for more details on correcting duplicate addresses.

Troubleshooting
Duplicate Act Net addresses
i-Vu Smart Valves come pre-addressed from the factory. If two actuators with the same address are on the Act Net together,
Duplicate address on network shows in the control programs Driver > Act Net Network Details > Properties tab > Act Net
Statistics > Device Status column.
For example, if two actuators with address 4 are on the network, the error Duplicate address on network appears in the row with
Device Address 4.
Resolution:
1. Choose one actuator to assign as the vacant address.
2. Make a note of the actuators serial number, found on the side of the actuator.
3. Enter the serial number in the Act Net Address Setting > Serial Number.
4. In the Device drop-down list, select either Reheat Valve-1 for address 4 or Reheat Valve-2 for address 5.
5. Click Accept.
6. If the address change is successful, Success is displayed for Operation Status.
21
7. When the controller recognizes that the conflict is resolved, both Device Status fields display Normal Operation.
