Emerson Fisher Type 99 User Manual

Type 99
2
Description
The Type 99 gas regulator provides a broad capacity
for controlled pressure ranges and capacities
in a wide variety of distribution, industrial and
commercial applications.
A Type 99 regulator has a Type 61L, 61LE or 61LD
(low pressure); Type 61H (high pressure); or Type 61HP
(extra high pressure) pilot integrally mounted to the
actuator casing as shown in Figure 1. The Type 99
regulator can handle up to 1000 psig / 69.0 bar inlet
pressure (the 1000 psig / 69.0 bar regulator requires
a Type 1301F pilot supply regulator and a Type H110
pop relief valve). The pilot supply regulator reduces
inlet pressure to a usable 200 psig / 14 bar for the
extra high-pressure pilot. The standard Type 99
regulator comes with O-ring seals on the guide
bushing and valve carrier to keep main valve body
outlet pressure from interfering with outlet pressure in
the lower casing assembly.
Specications
Specications and ratings for various Type 99 constructions are listed in the Specications section below. Some
specications for a given regulator as it originally comes from the factory are stamped on the nameplates located on
the pilot and actuator spring cases. An additional nameplate may be installed on the pilot to indicate a regulator with
O-ring stem seal. These regulators and their installations should be checked for compliance with applicable codes.
1. The pressure/temperature limits in this Instruction Manual and any applicable standard or code limitation should not be exceeded.
2. For stability or overpressure protection, a pilot supply regulator may be installed in the pilot supply tubing between the main valve and pilot.
Available Constructions
Type 99L - Type 99 with Type 61L pilot which
has 2 in. w.c. to 20 psig / 5 mbar to 1.4 bar
pressure range
Type 99LD - Type 99 with Type 61LD pilot
which has a narrower proportional band than the
standard Type 61L pilot
Type 99LE - Type 99 with Type 61LE pilot which
has a broader proportional band than the standard
Type 61L pilot
Type 99H - Type 99 with Type 61H pilot which has
10 to 65 psig / 0.69 to 4.5 bar pressure range
Type 99HP - Type 99 with Type 61HP pilot has
35 to 100 psig / 2.4 to 6.9 bar pressure range
