Step 6: Main Gas Shut-Off Valve Train
Component Selection
Eclipse can help in the design of a main gas shut-off valve
train that satisfies the customer and complies with all local
safety standards and codes set by the authorities within
that jurisdiction. Contact Eclipse for further information.
NOTE: Eclipse supports NFPA regulations (two gas shut-
off valves as a minimum standard for main gas shut-off
systems).
Valve Train Size
Fuel pressure supplied to the ratio regulator inlet must be
within the range specified in the RatioMatic datasheet.
The valve train should be sized sufficiently to provide the
specified pressure.
■ Do not operate RatioMatic burners with gas inlet
pressure less than the minimum listed on the
RatioMatic datasheet. Lower gas inlet pressure
may cause the ratio regulator to remain fully open
at lower inputs as the burner transitions from low
to high fire. This can result in the possible
accumulation of unburned fuel in the burner
which, in extreme situations, could cause a fire or
an explosion.
