OPERATING PRINCIPLE

This valve has two open positions and is equipped with
a regulator. The regulator sets the hydraulic brake
activation point which, in turn, causes rapid release of
the opening first stage. After the initial release, the brake
cuts in, ensuring that the valve continues to open slowly.
This valve is also equipped with two gas flow regulators:
one for the first flame and the other for the second.
Setting the initial rapid release trip
To set the initial rapid release trip, unscrew the protection
cap "F" and use the back of the cap as a tool to turn pin
"G". Turning clockwise decreases the gas flow, turning
counter-clockwise increases it.
This done, screw down cap "F in its original position.
Setting gas flow for the 1
Before setting the gas flow for the 1
loosen screw "D" (unpainted screw with raised cylindrical
head). After the gas flow has been set, remember to
tighten this screw once more.
N.B. To open to the 1
regulation ring "L" counter-clockwise by at least
one full turn. To set the gas flow for the 1
turn knob "E": turning it clockwise decreases gas
flow, turning it counter-clockwise increases it. Full
travel of regulator "E" for the 1
is approximately 3
is fully open, the gas flow to the 1
approximately 40% of the total available when the
valve is fully open in the second position.
Setting gas flow for the 2
Loosen screw "D" (unpainted screw with raised
cylindrical head).
To set the gas flow for the 2
it clockwise decreases gas flow, turning it counter
clockwise increases it.
This done, tighten screw "D". Full travel for regulator
"L" for the 2 nd flame, from + to -, is approximately 5
turns.
