Introduction

Triatek’s Universal Valve Module (UVM) is designed to allow for

interoperability between Triatek Venturi valves and third party

controllers.

Each Triatek valve is individually calibrated and has its own

unique position to cubic feet per minute (cfm) curve. The UVM

enables you to create a linearization curve in each controller for

each associated valve. It also allows you to span, scale, and

linearize the feedback sensor to obtain useful information from it.

Overview of Operation

A diagram of the basic functionality of the UVM is shown in

Figure 1.

The UVM takes a 0 -10 V signal from the third party equipment,

and depending on the scaling setting, interprets this as a 0 –

xxxx cfm request signal. The UVM is pre-programmed with the

associated valve’s linearization curve, and will move the valve’s

actuator to the correct position for the requested cfm.

Each valve is tted with an electronic position sensor on the lever

arm at the point of entry into the valve body (see Figure 1). The

electronic position sensor is used to provide actual valve position

information to the controllers. This signal is non-linear, and has a

random 0 and 100% position voltages.

It converts the sensor signal to a position on the valve and then

translates that to a cfm value. The cfm value is in turn output

from the UVM as a 0 – 10 V signal at the same scaling as the

cfm request signal.

The 0 -10 V signal is processed by the valve’s calibration

settings as set by the factory. The user has the ability to access

and adjust this curve if so desired. The subsequent signal is

then converted to an equivalent cfm request value. This value

is dependent on settings provided by the factory as applicable

for the associated valve size. The user can modify this signal if

desired.

The factory default settings relative to valve size are:

8 in. valve 10 V = 800 cfm

10 in. valve 10 V = 1100 cfm

12 in. valve 10 V = 1600 cfm

14 in. valve 10 V = 2300 cfm

The equivalent cfm request value is applied to the calibration

curve as entered by the factory for the associated valve and a

corresponding valve position value is generated.

This position value is applied to the actuator output voltage

calibration section and output to the actuator. The consequent

result is that the actuator will move to the required position so

that the valve passes the requested cfm.

As the valve moves to position, the position feedback sensor

moves as well. The signal from this sensor is processed by a

sensor voltage to position calibration section. The output of this

section provides an accurate position value. The position value is

applied to the position to cfm mapping table and a corresponding

cfm value is output.

This cfm value is then passed through cfm to voltage scaling

factor and converted to a voltage value. This value is then

passed through the factory set output calibration section and

made available to the voltage output for use by the third party

equipment as the actual valve cfm.

In certain circumstances the feedback signal may not match the

requested cfm signal. If 0 cfm is requested (0V input), and the

valve is a partially closed valve, the valve has a minimum cfm

that it can attain. This value is not 0 and for a 12 in valve would

be around 90cfm. In this case the feedback signal would be the

equivalent of 90 cfm or 0.56V for a 10V = 1600 setting.

If a UVM for an 8 in. valve is set with an arbitrary scaling of 10V

= 1100 cfm (or 110 cfm / volt), and a request signal of 9 V (or 990

cfm) is input to the unit, then the actuator will end up driving to

100%, as the maximum the valve can do is 700 cfm. The voltage

feedback output signal will only be around 6.4 V as the actual

valve cfm would be around 700.

Figure 2. UVM Use with DP Switch

Digital Input DP Switch

The UVM has the ability to accept a digital input DP switch. The

pneumatics of the DP switch are connected across the valve, and

the factory supplied switch is set to trip at 0.6 in. W.G.

Any pressure across the valve below this is to be interpreted as

the valve cfm is inaccurate or non-existent. The DP switch signal,

when enabled in the UVM, is used to provide a 0 cfm feedback

signal should the pressure across the valve drop below the 0.6

in. W.G. threshold.

The DP switch functionality can also be implemented by using

a pressure sensor with a 0-5 V output. The UVM can accept the

0-5 V signal and, via user gain and o󰀨set settings, convert it to an

internal pressure value.

Typically a 0-4 or 5 in. W.G. sensor would be used. When

enabled in the UVM, this value can be compared to a minimum

pressure value (typically 0.6 in. W.G.) as a threshold below

which, as like the DP switch, the cfm feedback signal goes to 0.

Figure 4. UVM use as a VAV Interface

The UVM can also be made to operate with a variable air volume

(VAV) box instead of a Venturi valve. In this case, instead of

providing the UVM with a cfm request signal, the input will

be interpreted as an actuator position signal where 0-10 V

represents a 0 -100% position signal.

This signal only provides positioning information for the VAV

box. The feedback sensor signal is replaced by the VAV box

ow probe pressure signal. This voltage signal is scaled and

converted to an internal pressure value.

The pressure value is then square-rooted and multiplied by a K

factor to obtain an internal velocity value. The velocity value is

multiplied by a duct area value to obtain an internal cfm value.

This cfm value is then scaled to the appropriate voltage, passed

to the Vo feedback voltage signal for use by the third party

controller. The scaling, K factor, and area can be set by the user

with the UVM Conguration Tool.

Figure 5. UVM Module DIP Switch Functions

Other than through the UVM Conguration Tool, the user does

not have access to any settings or operating modes of the UVM.

The exception is that the input and output signal modes and the

normal/reverse operation can be set via the DIP switches if that

functionality is enabled in the UVM.

The inputs and outputs can be set to be interpreted as a

Percentage (0 – 10 V = 0 – 100%) control or feedback signal, or

as a cfm ( 0 – 10 V = 0 – xxxx cfm ) control or feedback signal.

DIP switches 6 and 7 are used for this function. DIP switch 5 is

Normal Reverse Selection.

The UVM can communicate with the UVM Conguration Tool. To

this end, the UVM can reside at one of 16 hardware addresses.

These addresses are set via DIP switches 1, 2, 3, and 4. Via

the UVM Conguration Tool, the UVM is able to have up to an

additional 16 software addresses set for communications use.
