Checking the usage
Intended use
Gas solenoid valve for safeguarding gas or air on
various 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.
WARNING
Cleaning work on the solenoid actuator may not
be performed using high pressure and/or chemi-
cal cleaning agents. This can cause moisture to
get into the solenoid actuator and may lead to a
dangerous failure.

Installation
CAUTION
Please observe the following to ensure that the VG
is not damaged during installation and operation:
– Do not clamp the unit in a vice. Only secure the
flange by holding the octagon with a suitable
spanner. Risk of external leakage.
– Do not install or store the unit in the open air.
– Check max. ambient temperature– see type
label.
– Check max. inlet pressure– see type label.
▷
Installation position: black solenoid actuator in
the vertical upright position or tilted up to the
horizontal, not upside down.
> 20 mm
▷ The housing must not be in contact with masonry.
Minimum clearance 20mm (0.79").
> 20 mm
▷ Sealing material and dirt, e.g. thread cuttings,
must not be allowed to get into the valve housing.
▷Install a filter upstream of every system.
▷Use approved sealing material only.
▷Use a suitable spanner.
▷Ensure that there is sufficient space for installa-
tion and adjustment.
▷On VG 10/15 –40/32, the inlet pressure pucan
be measured at the pressure test point

Gas compression fittings
▷ The seals in some gas compression fittings
are approved for temperatures of up to 70°C
(158°F). This temperature limit will not be ex-
ceeded if the flow through the pipe is at least
1m3/h (35.31SCFH) of gas and the maximum
ambient temperature is 50°C (122°F).

Wiring
WARNING
Attention! Please observe the following to ensure
that no damage occurs:
– Electric shocks can be fatal! Before working
on possible live components, ensure the unit
is disconnected from the power supply.
– The solenoid actuator heats up during opera-
tion. Surface temperature approx. 85°C (approx.
185°F) pursuant to EN 60730-1.
▷ Use temperature-resistant cable (>80°C/176°F).
▷Wiring to EN 60204-1.
 Disconnect the system from the electrical power
supply.
 Shut off the gas supply.
▷ The solenoid actuator can be rotated to allow
it to be repositioned for electrical connection.
On VG..N, the hexagonal nut/cap on the solenoid
actuator must be loosened for this.

Tightness test
CAUTION
Please observe the following to ensure that the VG
is not damaged during the tightness test:
–Check max. inlet pressure– see type label.
–Test pressure ≤1.5x max. inlet pressure.
▷The tightness test procedure on VG is function-
ally the same for all nominal sizes. The following
figures apply to all VG variants by way of example.
 Close the solenoid valve.
 Shut off the gas supply.
 To be able to check the tightness, shut off the

Maintenance
CAUTION
In order to ensure smooth operation: check the
tightness and function of the VG every year, or every
six months if operated with biologically produced
methane.
 Disconnect the system from the electrical power
supply.
 Shut off the gas supply.
▷ If the flow rate is correct, see page4 (Tight-
ness test).
▷If the flow rate has dropped, clean the strainer.

Checking tightness and function
▷
When the solenoid actuator is removed, the
gas-filled space in the VG is opened. Therefore,
check for tightness once the actuator has been
reinstalled.

▷ In order to determine whether the VG is tight and
closes securely, check the internal and external
tightness, see page4 (Tightness test).
▷
Check electrical installations in line with local reg-
ulations; pay particular attention to the PE wire.
Assistance in the event of
malfunction
WARNING
Electric shocks can be fatal! Before working on
possible live components, ensure the unit is dis-
connected from the power supply. Fault-clearance
must only be undertaken by authorized trained
personnel. Unauthorized repairs or incorrect elec-
trical connections can cause the solenoid valve to
become defective. In this case, our warranty will
be rendered void.
? Fault
! Cause
•Remedy
? The solenoid valve does not open, there is
no flow downstream of the solenoid valve.
! There is no power supply.
• Have wiring checked by authorized trained per-
sonnel.
! Guiding elements bent. Incorrect handling when
installing the unit.

range accelerates the ageing of the elastomer ma-
terials and reduces the service life (please contact
manufacturer).
