CHECKING THE USAGE

Intended use

valVario ﬁlter module VMF, measuring oriﬁce VMO and

ﬁne-adjusting valve VMV for installation in gas control

and safety systems in the ﬁelds of industrial and com-

mercial gas heat generation.

VMF

with replaceable ﬁlter pad insert to protect against

soiling of downstream appliances.

VMO

with replaceable oriﬁce insert. For use as a restricting

or measuring oriﬁce.

VMV

Fine-adjusting valve for presetting the gas or air ﬂow

rate to gas burners or gas appliances.

This function is only guaranteed when used within the

speciﬁed limits– see page 7 (Technical data). Any

other use is considered as non-compliant.

INSTALLATION

CAUTION

Incorrect installation

Please observe the following to ensure that the

unit is not damaged during installation and oper-

ation:

– Dropping the device can cause permanent

damage. In this event, replace the entire device

and associated modules before use.

➔Installation position: install the VMF with the base

plate pointing downwards or sideways, otherwise

dirt can collect in the housing when replacing the

ﬁlter pad. The VMV can be installed as required;

when ﬁtting to pressure regulator VAD, VAG or VAV,

the base plate must be facing the same direction

as the regulator body. VMO can be installed as

required.

➔Installation position when using valVario controls:

VMF is ﬁtted upstream of the control, VMV is ﬁtted

downstream of the control. When used as a restrict-

VMF, VMO, VMV · Edition 01.20

EN-3

ing oriﬁce, the VMO is ﬁtted downstream of the control.

VMV, VMOVMF

➔

Installation position with inlet and outlet ﬂang-

es: VMF, VMV and VMO may be inserted at

any position in the pipework. When used as a

measuring oriﬁce, the length of the inlet and

outlet section of the VMO must be ≥ 5 DN.

VMF, VMV VMO

≥ 5 DN

➔The housing must not be in contact with masonry,

minimum clearance 20mm (0.79").

➔Sealing material and thread cuttings must not be

allowed to get into the housing.

➔

A ﬁlter must be installed upstream of every system.

➔Ensure that there is sufﬁcient space for installation

and adjustment.

➔Do not store or install the unit in the open air.

CAUTION

Incorrect installation

Please observe the following to ensure that the

unit is not damaged during installation and oper-

ation:

– Only secure the device by holding the octagon

on the ﬂange with a suitable spanner. Risk of

external leakage.

1 2 3

➔Both O-rings or the O-ring and double block seal

must be ﬁtted.

WARNING

Risk of leakage.

Please note the following:

– If VMF, VMO or VMV has been delivered with

two ﬂanges and is subsequently attached to a

valVario control, a double block seal must be

used instead of the O-ring. The double block

seal must be ordered separately, see accesso-

ries, seal set for sizes 1–3.

VMV

➔

If the ﬁne-adjusting valve VMV is ﬁtted downstream

of a pressure regulator VAD, VAG or VAV, a differ-

ential pressure oriﬁce with rubber seals Gmust

be inserted at the outlet of the pressure regulator.

TIGHTNESS TEST

1 To be able to check the tightness, shut off the

downstream pipeline close to the VMF, VMO, VMV.

2 3

4 5

6 7

8 Tightness OK: open the pipeline.

➔

Pipeline leaking: check O-rings. When installing on

a valVario valve or pressure regulator, check the

O-ring and, if ﬁtted, the double block seal.

➔

Unit leaking: dismantle the VMF, VMO or VMV and

return it to the manufacturer.

CAUTION

Please observe the following to ensure that the

unit is not damaged during operation:

– Do not overturn the adjusting screw, as the

ﬁne-adjusting valve then can no longer be

adjusted.

➔The VMV can be adjusted from two sides.

MAINTENANCE

CAUTION

In order to ensure smooth operation:

– Check the VM for tightness annually, or every

six months if operated with biogas.

VMF: replacing the ﬁlter pad

➔If the ﬂow rate is correct, check for tightness – see

page 3 (Tightness test).

➔If the ﬂow rate has dropped, replace the ﬁlter pad.

1 Disconnect the system from the electrical power

supply.

2 Shut off the gas supply.

TECHNICAL DATA

Gas types:

natural gas, LPG (gaseous), biogas (max. 0.1 %-by-

vol. H2S) or air; other gases on request.

The gas must be dry in all conditions and must not

contain condensate.

Max. inlet pressure pu:

500mbar (7.25psig).

Medium and ambient temperatures:

-20 to +60°C (-4 to +140°F), no condensation

permitted.

Long-term use in the upper ambient temperature

range accelerates the ageing of the elastomer ma-

terials and reduces the service life (please contact

manufacturer).

Storage temperature: -20 to +40°C (-4 to +104°F).

Housing: aluminium.

Connection ﬂanges:

with internal thread: Rp to ISO 7-1, NPT to ANSI/

ASME,

with ISO ﬂange: DN 40 and DN 50 to ISO 7005.

DESIGNED LIFETIME

This information on the designed lifetime is based on

using the product in accordance with these operat-

ing instructions. Once the designed lifetime has been

reached, safety-relevant products must be replaced.
