OVERVIEW OF PRODUCT VERSIONS

FUNCTION

VLV55|VLV65 with rubber lip seal

Round volumetric flow controller

 Volumetric flow range 0.5-5 m/s (VLV55) or 1-8 m/s (VLV65)
 With rubber lip seal (-GD1)

Round volumetric flow controller

 Volumetric flow range 0.5-5 m/s (VLV55) or 1-8 m/s (VLV65)
 With flat flange according to DIN 24154, class 5 (-FF1)

VLV55|VLV65 with METU flange

A volumetric flow controller is used for pressure-independent

volumetric flow regulation in ventilation and air-conditioning

systems. It serves to keep the volumetric flow either constant

within specified limits (CAV) or to control it variably (VAV).

The housing, measuring nozzle and the controller with pressure

sensor form a closed control loop with feedback, allowing de-

mand-dependent, energy-saving air-conditioning of the single

rooms or areas of air-conditioning systems also at low duct

pressures and air velocities. When suitable controller types are

used, room or duct pressure regulation can be achieved.

For the measurement of the effective pressure, SCHAKO is us-

ing its measuring method by means of a standardised Venturi

nozzle made of aluminium to DIN EN ISO 5167. In front of the

Venturi nozzle and in the nozzle neck, the volumetric flow con-

troller is fitted with openings for pressure take-off. The result-

ing differential pressure (effective pressure) is measured and

evaluated by a universal or compact controller. The VLV meas-

urement principle allows measurement of small volumetric

flows. In comparison with measuring rods, measuring crosses

or measuring orifices having fewer measuring points, this gives

higher accuracy, allowing the inflow area required in front of

the volumetric flow controller to be omitted. This also allows

smaller measurement tolerances to be achieved.

The volumetric flow controllers of the VLV type are insensitive

to dirt caused by dust and can be installed and used inde-

pendently of their position. The mounting instructions docu-

mented by the manufacturer must be adhered to, as otherwise

the correct functioning of the volumetric flow controller is not

guaranteed. The volumetric flow controllers type VLV are not

suitable for air containing sticky and greasy particles (e.g.

kitchen exhaust air).

Round volumetric flow controller

 Volumetric flow range 0.5-5 m/s (VLV55) or 1-8 m/s (VLV65)

Areas of application | Processing

AREAS OF APPLICATION

PROCESSING

 for supply and return air systems with low pressures

and low air velocity

 for constant CAV or variable VAV installations
 for positive control V
 For volumetric flow and linear pressure control
 at ambient temperatures 0° to +50°C,

requirement: measuring air 0...+50°C/5...95% rH,
non-condensing

 for regulating the air velocity in the duct in

the range of 0.5...8 m/s

 VLV55 for air velocity 0.5 - 5 m/s
 VLV65 for air velocity 1 - 8 m/s
 Minimum pressure difference of 5 - 150 Pa

When using volumetric flow controllers in roof central units, in
extreme cases, condensation can build up in the measuring
pipes of the volumetric flow controller as a result of the large
temperature differences between the air flowing through the
volumetric flow controller and the surrounding air. This con­densation may affect or damage the sensor. This is why for this
field of application care must be taken to insulate the housings
of the volumetric flow controllers and the measuring hoses (to
prevent condensation) and to mount the controllers in such a
way that any condensate formed on the outside of the measur­ing hoses can run downward and be drained (without entering
the sensor).

When connecting SCHAKO components to customer installa­tions, any compatibility problems are beyond our scope of re­sponsibility and must be solved on site.

TECHNICAL DATA OF CONTROL COMPONENTS

Measured value collection and control function

The volumetric flow controllers of the Belimo make, type LMV­D3-MP/-MF Compact and the Gruner make, type 227VM Com­pact are delivered by SCHAKO as standard with the operating
mode (Y signal, U5 signal) 2-10 V DC. When activated by 2 V DC,

volume is controlled, the smallest possible V

the V

min

that can be controlled can be seen from the "Volumetric Flow
Range" tables.

NOTE: When the air volume drops below the V

min

table, the correct functioning of the volumetric flow controller
is no longer guaranteed!

Positive control damper "CLOSED"

Airtight sealing to DIN EN 1751 is achieved on site either via a
positive control "CLOSED" by means of a switch or a relay, or
via an actuator signal of 0 V DC applied to the input Y (all Com­pact controllers equipped with the operating mode 2-10V DC).
Accordingly, the drive will likewise close the flap in operating
range 2 - 10 V DC (however, this does not apply to the operat­ing range 0-10 V DC), and the VAV control will be inactive. To
do so, it must be ensured that the actuator signal is < 0.1 V DC.
This is why in rooms where defined pressures are active (e.g. la­boratories), the damper should be closed via a digital on site
switching contact.

If the Compact controllers of the Belimo make must be deliv­ered with the operating mode 0-10V DC on customer request,
please note that a positive control "CLOSED" can only be ef­fected via a switching contact with diode.

If the compact controllers of the Belimo make are used to­gether with the type VRP-VFP-300 in the master/slave mode or
in parallel mode, then only the 2-10 V DC operating mode is
usually possible.

Positive control damper "OPEN"

Supports smoke extraction or is used as a safety position. The
volumetric flow controller is in this case inactive, and the
damper is driven to the mechanical open position.

Depending on requirement or by not assigning them, individual
areas can be set to stand-by operation. In this way, minimum
room flushing with greatly reduced energy expenditure is
achieved.

V

control to a maximum volumetric flow

max

Individual or several rooms are supplied for a short period with
a maximum volumetric flow. This allows, for example, a room
through-ventilation or efficient heating to be effected.

Continuous operation

As a function of the continuous driving signal and the pro­grammed operating range (0-10 V DC or 2-10 V DC), the volu­metric flow controller will regulate the volumetric flow linearly

...V

between the setpoint values V

min

max

.

Constant operation

If terminal 3 (Y driving signal) has not been assigned, the air vol­ume set on the V

potentiometer will be set to a constant vol-

min

ume.

Two-stage volumetric flow rate control

Stage 1: If terminal 3 (Y command signal) has not been

assigned, the air volume set on the V

potenti-

min

ometer will be set to a constant volume.

Stage 2: If AC 24 V is applied to terminal 3 (Compact con-

troller) or terminal 7 (VRD3-SO, VRP-VFP-300),
the VSR will keep the value set on the V

max

po­tentiometer constant. With a switch or a contact
in a connection line a "secondary volume flow
control" is possible.

ZTH EU as MP level converter

Description

The ZTH EU is also a potential-free interface between the USB
port of a PC and the Belimo MP bus. It is used to connect the
Belimo PC-Tool directly to the MP bus or directly to a program­mable MFT drive.

Power supply

The ZTH EU is supplied with power by the USB port. The MP bus
voltage is obtained internally by means of DC/DC converter.
This is why no external power supply is necessary.

Driver

To be able to work with the ZTH EU, a suitable driver must be
installed on the PC. The driver can be downloaded from the
Belimo website (download section). After installation of the
driver, the ZTH EU device will log in to the PC as a virtual COM
interface.

Note

For connection to USB ports of PCs and BELIMO 24 V drives
only (to safety extra low voltage SELV or US class 2 feeds)

min

and

used to switch from 2 - 10 V DC to 0 - 10 V DC.

Connection

The GUIV-A can be connected electrically to 227 V via the U/PP
connection by direct on site or remote control, for example in a
switch cabinet.

Structure and operation

The relevant parameters can be set and queried in the individ­ual menu items, while the operating parameters programmed
in-factory can be queried under menu item 10.

Note

As long as the U/PP connector is connected to the GUIV-A, the
output signal U does not correspond to the actual value.

SPECIFICATION TEXT

VLV55 | VLV65

Volumetric flow controller in round design, for round ductwork
connection, for use in supply and return air systems for con­stant or variable volumetric flow regulation.

Measurement of the volumetric flows according to the Venturi
principle. Standardised Venturi nozzle with measuring points
for differential pressure measurement in front of the nozzle
and in the nozzle neck. This ensures high control accuracy at
low air velocities, duct pressures and any inflow conditions.

Nozzle and differential pressure sensor are resistant to pollu­tion. Connecting pipe is suitable for air ducts to DIN EN 1506.
Position of the control damper is visible from outside.
Leakage at the damper blade to DIN EN 1751, class C.
Housing leakage to DIN EN 1751, class 4.

Special features

 designed for use at low air velocities and duct pressures
 position-independent installation possible
