Gas cocks are used to manually
shut-off the gas supply on both
sides of the main gas shut-off
valve train.

Solenoid Shut-Off Valve
(Normally Closed)
Solenoid valves are used to
automatically shut off the gas
supply on a bypass gas system or
on small capacity burners.

Pressure Regulator
The pressure regulator reduces
gas pressure to a stable, usable
pressure.
684
Ratio Regulator
A ratio regulator is used to control
the air/gas ratio. The ratio
regulator is a sealed unit that
adjusts the gas flow in ratio with
the air flow. To do this, it measures
the air pressure with a pressure
sensing line, the impulse line. This
impulse line is connected between
the top of the ratio regulator and
the burner body.
