FLOW ADJUSTMENT
The GSAV series solenoid valves are fitted with a
flow adjustment device as standard. This device
acts by limiting the opening of the shutter and
allows the gas flow to be regulated from 30 to 100%
To adjust the quantity of gas that passes,
unscrew the hexagonal screw (10) on the upper
part of the coil.
In this way, the coil-stopping washer (9) can be
removed to access the adjustment screw (8)
inside the sleeve of the valve with a flat head-
ed screwdriver. At this point, turn the adjust-
ment screw clockwise to reduce the flow of
the valve and anti-clockwise to increase it.
When the screw is completely tightened the shut-
ter is closed and therefore no gas passes, while
the maximum gas flow is obtained with the screw
completely loosened.
