Combination controls CG 15 -30
Combination controls CG 15-30
Complete with strainer,
two safety valves (Class A) and servo-
govemor für maximum control
accuracy
Application
The combination controls are type-
tested and certitied pursuant to the Gas
Appliance Directive (90/396/EEC) in
conjunction with
EN 126 and EN 12067-1.
Function
The incorporated, power-saving linear
compressor increases the inlet gas
pressure level for opening and con-
trolling the valves. In conjunction with
the servogovernor, this results in a high
control accuracy over a wide inlet press
ure range up to 360 mbar at low control
pressures and with only slight pressure
difference between inlet
and outlet pressure.
The first valve can be controlled sepa-
rately (e.g. in conjunction with a pilot
gas supply connection in the interme-
diate space).
