Technical data
Gas types: natural gas, town gas, LPG (gaseous),
biologically produced methane (max. 0.1 %-by-
vol. H
2
S, VG..M only) or clean air; other gases on
request. The gas must be dry in all temperature
conditions and must not contain condensate.
Max. inlet pressure p
u
: see type label.
Opening time:
VG..N: quick opening, ≤ 1 s.
VG..L: slow opening, 10 s.
Closing time:
VG..N, VG..L: ≤ 1 s.
Ambient temperature: -20 to +60°C (5 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 (68 to 104°F).
Safety valve:
Class A, Group 2 pursuant to EN 161.
Mains voltage:
220/240 V AC, +10/-15%, 50/60 Hz,
120 V AC, +10/-15%, 50/60 Hz,
24 V DC, +10/-15%.
