First
Stage Regulators
 First-stage
Regulators reduce tank pressure to a lower pressure (usually 10 psig)
for a second-stage regulator. Fisher First-Stage Regulators are painted
red for easy identification. Vents are screened with standard orientation
over outlet.
2 PSIG Regulators
2-PSI Service Regulators are designed for 2-PSI LP-Gas regulator systems.
They are installed downstream from a first-stage regulator and reduce
an inlet pressure of 10 PSIG to a nominal 2 PSIG outlet pressure.
2-PSI Service Regulators are designed for domestic applications that
supply LP-Gas through corrugated stainless steel tubing to a line
regulator located inside the building. Fisher 2-PSI Service Regulators
are powder-coat painted white for easy identification.

 Second
Stage Regulators
Second-Stage Regulators Reduce the pressure from a first-stage unit
to 11-inch water column in domestic installations. Vents are screened
with standard orientation over inlet and other vent orientations available.
Fisher Second-Stage regulators are normally painted palm green for
easy identification.
Integral Two Stage Regulators
Integral Two-Stage Units combine a First-Stage Regulator and Second-Stage
Regulator into one compact unit. Recommended for installations where
piping distance is short, integral two-stage regulators provide all
the advantages of two-stage regulation.
Fisher Integral Two-Stage Regulators are color coded gray for easy
identification. Vents are screened with standard second-stage orientation
over outlet.

 Commercial/Industrial
Regulators
For large loads such as factories, office buildings, restaurants,
etc., Fisher has a variety of commercial/industrial regulators. The
higher capacities on commercial and industrial installations typically
require a two-stage regulator system.
High Pressure Regulators
High Pressure Regulators (pounds to pounds) typically reduce tank
pressure to an intermediate pressure for use by another regulator.
They may be used as high pressure regulators on distribution systems
in conjunction with a first-stage downstream regulator.
They are also used for final stage service on high pressure burners
in crop dryers and tobacco curers, as well as other medium sized commercial/industrial
applications. |
 Marshall
Gas Control Regulators
Low Pressure Single Stage Regulators
Marshall Low Pressure Regulators are available with a drip lip
vent configuration. They are approved for use on small portable appliances
or outdoor cooking appliances that utilize low pressure.
Low Pressure Two Stage Regulators
The Marshall Two-Stage Changeover Regulator offers the convenience
of changeover, switching from gas cylinders to full gas cylinders.
The top portion of the the changeover is a dual high pressure regulator,
which reduces container pressure to approximately 10 to 15 PSIG and
sends it to the second stage regulator. The second stage regulator
then completes the regulation process, reducing the inlet pressure
to 11 inches of water column outlet pressure.
Single Stage 90 Degree Regulator
The Single Stage 90 Degree Regulator's size, shape and flow characteristics
make them ideal for use on propane appliances that require 100,000
BTU or less. A variety of connection options are also available.
Adjustable High Pressure Regulator
The Marshall Adjustable High Pressure Single-Stage Regulator is designed
for use with appliances that require pounds per square inch of pressure
instead of WC inches. The improved knob design assures quality service
and positive valve closure.
