1. The pressures shown in the table are the minimum supply pressures required by the pilot. If the inlet pressure is less than shown, an external pilot supply is necessary.
Installation and Startup
Personal injury, equipment damage or
leakage due to escaping accumulated gas
or bursting of pressure-containing parts
may result if this gas blanketing regulator
is overpressured or is installed where
service conditions could exceed the limits
given in the Specifications section and
on the appropriate nameplate or where
conditions exceed any ratings of the
adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by Title 49, Part 192,
of the U.S. Code of Federal Regulations;
by the National Fuel Gas Code Title 54 of
the National Fire Codes of the National
Fire Protection Association; or by other
applicable codes) to prevent service
conditions from exceeding those limits.
Additionally, physical damage to the
gas blanketing regulator could result in
personal injury and property damage due
CAUTION
to escaping accumulated gas. To avoid
such injury and damage, install the gas
blanketing regulator in a safe location.
On the Type EGR main valve, a normal
pressure drop assists shutoff. Therefore,
leakage (backflow) may result during any
reverse pressure drop condition.
1.
Use qualified personnel when installing, operating
and maintaining regulators.
2. Before installing, inspect the main valve, actuator,
pilot, supply pressure regulator and tubing for any
shipment damage or foreign material that may
have collected during crating and shipment. Make
certain the body interior is clean and the pipelines
are free of foreign material.
3. Apply pipe compound only to the external pipe
threads with a threaded body or use suitable
line gaskets and good bolting practices with a
flanged body. Ensure that the spring case of the
Type T205 pilot is pointing down; changing the
orientation of the pilot may affect the spring range.
