The Path To Technology Leadership

In 1880 Fisher Controls was founded in
Marshalltown, Iowa, by William Fisher.

Fisher Controls grew steadily over the years,
evolving into an industry leader offering

customers the most complete range of ow

control products in the world.

William Fisher came to America from
England as a boy of 14. As his family
ventured west in the new land, they settled
along the Mississippi in Clinton, Iowa. It
was there, as a mechanic in a small engine
shop for 10 years, that William learned about
steam, the major source of power in the late
1800s. Because of his experience in water
and steam, William, who was 24 at the time,
was invited to Marshalltown to help install
the water works.

The idea of a control device was born in the

engineer ’s mind as a re raged in the city.

Working through the night, William Fisher
hand-throttled the steam-driven pumps to
maintain pressure in the city’s mains. During

that re, he saw a need for a device that would

both control the steam-driven pumps and
maintain them at a constant pressure.
Many months and trials later, William

Fisher was nally satised with one of his

designs and began manufacturing what we
know today as the Fisher Type 1 constant
pressure pump governor. He was granted a
patent in 1884.

One thing remained the same since William

Fisher’s rst Type 1 pump governor: a pledge

to unequalled quality. Today, the brand name
Fisher is synonymous with quality throughout
the world.

Re g u l a t o R s

LP-Gas regulators compensate for variation in tank pressure to supply

propane at a constant pressure to furnaces, burners, home appliances, farm

taps, commercial businesses, and industrial plants. The regulator must

deliver this pressure despite the intermittent use of the appliances and despite

varying flow demands.

In certain instances codes require two-stage regulation and regulator designs

are available that provide the two-stage reduction in one regulator. Many

regulators provide overpressure protection through an integrated internal

relief valve for overpressure protection, also required by some codes. Other

overpressure protection methods which are available include external relief

valves and monitors.

Introduction

The regulator truly is the heart of an LP­Gas installation. It must compensate for
variations in tank pressure from 8 to 250 psig
(0,55 to 17,2 bar) and deliver a constant outlet
pressure of LP-Gas typically at 11-inches wc
(27,4 mbar) to consuming appliances. The

regulator must deliver this pressure despite
the intermittent use of the appliances.

In propane service, NFPA 58 requires Two­Stage regulation on all fixed piping systems
that serve 1/2 psig (34,5 mbar) appliance
systems (normally operated at 11-inches wc
(27,4 mbar pressure). Two-Stage regulation
produces a nearly constant pressure to the

appliance and can result in a more efficient
LP-Gas operation for the dealer resulting
in less maintenance and fewer installation
call-backs.

With properly selected regulators, the
internal relief valve provides 2 psig (0,14 bar)
overpressure protection as required by
NFPA 58.

Emerson Process Management is a leading
international supplier of cost-effective
products, services, and solutions used in the
propane industry. Around the world, Fisher®
brand LP-Gas Equipment Distributors offer
quality products as well as applications

OVERVIEW

Emerson Process Management’s Fisher®
brand provides the most complete line of
regulators in the industry today. Pressure
reducing regulators supply LP-gas at
a constant pressure for commercial
applications such as furnaces and boilers
in industrial facilities to farm taps and
jurisdictional systems. These facilities
and systems provide several million BTU
per hour to small domestic and appliance
applications. Fisher brand regulators
are designed to the highest standards for
safe and accurate gas delivery, regardless
of variations in supply pressure. This
Application Guide briefly explains the types
of regulators available for these regulators.
Your local LP-Gas Distributor can assist
you in selecting the proper regulators and
accessories for your system.

COMMERCIAL/INDUSTRIAL HIGH- AND
LOW-PRESSURE REGULATORS

Commercial or industrial regulators are
often higher-volume devices that reduce
tank pressures of 250 psig (1,7 bar) to
pressures as low as 11-inches w.c. (water
column) (27 mbar). Flows can be as low
as 1 000 000 BTU/hr or as high as
100 000 000 BTU/hr.

FIRST-STAGE REGULATORS

A two-stage pressure-reducing regulator
system uses two regulators to cut the
supply pressure from the storage tank to
the appliance. The first-stage regulator
supplies a nearly constant inlet pressure
around 8 to 10 psig (0,55 to 0,69 bar) to
a second-stage regulator. This relative
constant pressure allows appliances to work
efficiently. To comply with requirements,
such as NFPA 58, a two-stage system is
used. The second-stage unit does not
have to compensate for widely varying
inlet pressures. The first-stage regulator
is often at the tank and the second stage at
the building or equipment being supplied.
Second-stage pressure can be adjusted as
desired. The first stage must be capable of
higher inlet pressures.

TWO-PSI REGULATORS

A two-psi pressure regulator is used as an
intermediate regulator after the first-stage
regulator. These regulators are designed for
2 psig (0,14 bar) LP-gas regulator systems.
These regulators feature a combination relief
valve and large vent that provide over pressure
protection and exceed UL requirements.

SECOND-STAGE REGULATORS

A two-stage pressure-reducing regulator
system uses two regulators to cut the
supply pressure from the storage tank to the
appliance. The two-stage system supplies
a nearly constant outlet pressure to the
appliance allowing the appliance to work
efficiently. To comply with requirements,
such as NFPA 58, a two-stage system is
used. The first-stage regulator is often at
the tank and the second stage at the building
or equipment being supplied. Second-stage
pressure can be adjusted as desired. The
second-stage regulator reduces the pressure
from a first-stage unit to 11-inches w.c.
(27 mbar) in domestic installations. Vents
are normally screened.

INTEGRAL TWO-STAGE REGULATORS

Integral two-stage regulators combine both
stages into one compact unit and are often
used for installations where piping distance
between the building being served and the tank
is short. Integral two-stage regulators provide
all the advantages of two-stage regulation.

FIVE REASONS TO USE A
TWO-STAGE SETUP

1. Ifrequiredforcompliancewithcode
  requirementssuchasNFPA58.

2. Fewertroublecalls

With a two-stage system, you can expect
fewer customer trouble calls due to regulator
freeze-ups from too much water in the gas. A
two-stage regulator reduces these possibilities
in two ways: First, a larger orifice can be

used, making it more difficult for ice to
build-up and block the orifice. Second,
more heat can be transferred through the
walls of two regulators than one.

3. Smallerpipeortubing

Due to the higher pressure between the
first and second-stage units, smaller pipe or
tubing can be used in a two-stage system.
These savings can make a two-stage system
more economical to install than a single­stage system.

4. Constantappliancepressure

With a two-stage system, a first-stage
regulator supplies a nearly constant inlet
pressure of 8 to 10 psig (0,55 bar to 0,69 bar)
to a second-stage regulator. This means that
the second-stage regulator does not have to
attempt to compensate for widely varying
inlet pressures. With more uniform pressure,
appliances work better, and customers are
less likely to experience problems that result
in service calls.

5. Keepdownstreampressurebelow
  2psig(0,14bar)

Second-stage and Integral two-stage
regulators have internal pressure relief
valves, which limit the outlet pressure
to 2 psig (0,14 bar) when the seat disc is
removed and the inlet pressure is 10 psig
(0,69 bar) or less as specified in UL 144,
STANDARD for LP-GAS REGULATORS.

WHEN TO USE A TWO-STAGE SETUP

Emerson Process Management recommends
Fisher brand two-stage systems whenever
the following conditions exist:

1. Compliancewithregulationcodes.

2. Thereisapossibilityofmoisturein
 theLP-gas.

3. Widefluctuationsingasdemandexist.

4. Winterandsummertemperatures
 varygreatly.steamheader.

64 Series High Pressure Regulators

Re g u l a t o R s

Introduction

The 64 Series adjustable high-pressure
regulators offer a wide range of available
pressure ranges. High-pressure regulators
usually reduce tank pressure to an
intermediate pressure for use by another
regulator. They may be used as high­pressure regulators on distribution systems

when used in conjunction with rst-stage

downstream regulators.

When equipped with an internal relief valve
(64SR Series), the regulator may be used as a

nal-stage regulator on high-pressure systems.
It may also be used as a rst-stage regulator

when set at 10 psig (0,69 bar) or less.

The 64KB Series has a special

Polytetrauoroethylene (PTFE) diaphragm

protector that makes it suitable for anhydrous
ammonia (NH3) service. The 1/4-inch FNPT
tapped and plugged side outlet can be used
to install a pressure gauge or a hydrostatic
relief valve.

Re g u l a t o R s

Introduction

The 67C Series is a Underwriters
Laboratories (UL) listed high-pressure
regulators that meets a variety of
applications in liquid or vapor service.
The compact body design makes the
67C Series particularly useful in
installations with space limitations.

The basic 67C Series regulators come
equipped with a wrench or handwheel
adjustment (67CW or 67CH Series). The
highly accurate 67CD Series eliminates
the need for a pressure gauge on portable
applications by using calibrated scales on
the spring case, allowing visual adjustment
of outlet pressure. The non-adjustable
67CN Series provides a tamper-resistant

spring case and one of three xed setpoints:

10, 15, or 20 psi (0,69; 1,0; or 1,4 bar).

The 67C Series carries a UL listing as a
high pressure, non-relief regulator. This
series contains brass materials that are not
compatible with anhydrous ammonia service.

99 Series Commercial/Industrial Regulators

Re g u l a t o R s

Introduction

The 99 Series commercial/industrial
regulator is a pilot-operated unit that keeps
outlet pressure constant despite varying

ow rates and inlet pressures. It can

be used for either low or high-pressure
applications while maintaining accuracy.

Ease of maintenance is only one of the
many features of the 99 Series. The
actuator diaphragm and pilot respond

simultaneously to control nal positioning

of the main valve, permitting full main
valve travel and higher capacity capabilities.

Type 289H Backpressure Regulator/Relief Valve

Re g u l a t o R s

Introduction

Available for settings between 0.5 to

2.25 psig (34 to 155 mbar), the 289 Series
relief valve is a throttling relief valve used
downstream of pressure regulators to protect
the downstream system from overpressure.
A smooth throttling action minimizes
pressure surges in the system during
emergency operation.

This unit features a pitot tube booster
to achieve the highest possible relief
capacity with a minimum buildup of the
system pressure.

A Type 289H relief valve is installed
between large second-stage regulators
(such as the S202G or S302G Series) and
the burner to provide high capacity relief.
They are ideal for low-pressure settings
due to the increased sensitivity provided by
the large diaphragm area.

Introduction

The Type 299H is a high capacity,
pilot-operated regulator, incorporating a
lightweight, 21 pounds (9,5 kg) design with
dependable operation. With a capacity
up to 38 million BTU/hr (428 SCMH),
the Type 299H is ideal for applications
from large commercial sites to smaller
multi-dwelling establishments. The unit
comes with a 1-1/2 or 2-inch threaded NPT
cast iron body with internal or external
registration. Internal registration allows
easy installation while external registration
provides higher accuracy. A 2-inch

(DN 50) anged body and steel body

material are also available. Alternate outlet
settings from 3.5-inches w.c. (9 mbar) to
60 psig (4,14 bar) are available.

The Type 299H has a maximum inlet
pressure rating of 150 psig (10,3 bar), so it

cannot be used as a rst-stage regulator.

627 Series Commercial/Industrial Regulators

Re g u l a t o R s

Introduction

The 627 Series commercial/industrial
regulator is a large capacity, high­pressure unit for use in conjunction with
S302G or S202G Series regulators. It

can also be used on nal-stage (psi to

psi) service. A 1805 Series relief valve
is recommended to prevent excessive
build-up in the downstream line.

The diaphragm case and/or regulator
body on the 627 Series can be rotated in
any of four positions to allow installation
in locations with limited space.

912 Series Pressure Reducing Regulators

36

Re g u l a t o R s

Introduction

The 912 Series direct-operated, spring-loaded
regulators are UL listed regulators used in a
variety of service and industrial applications.
These regulators have limited-capacity
internal relief across the diaphragm to help
minimize overpressure.

The 912 Series, with capacity ratings of less
than 100 000 BTU/hr (1,30 SCMH), are often
used on small portable outdoor appliances.

Underwriters Laboratory requires
horizontally mounted regulators to be
installed with vent opening protection to
prevent blockage by freezing rain. Vent
protector Type P331 can be used on a
horizontally mounted Type 912. The
protector should not be used if the regulator
is installed vertically with the vent pointing
downward or beneath a protective cover.

1805 Series Backpressure Regulators/Relief Valves

Re g u l a t o R s

Introduction

The 1805 Series relief valves protect
piping downstream of a regulator from
excessive pressure. They are usually

installed between rst and second-stage

regulators or in downstream lines from

high-pressure regulators used for nal-

stage service. Its internal parts can be
removed without taking the body out of
the line.

The relief valve includes a closing cap
and 1/4-inch threaded NPT vent over
the adjusting screw.

Type R130 Changeover Manifold Assemblies

54

Re g u l a t o R s

Introduction

Fisher® brand automatic changeover
regulators change from the supply cylinder
(when gas is exhausted) to the
reserve cylinder automatically.

The Type R130 changeover manifold
assemblies are composed of two Type 67C
regulators and a special 0 to 60 psig (0 to
4,1 bar) pressure gauge, the Type R130-20
delivers a 45 psig (3,1 bar) outlet pressure
on supply and 30 psig (2,07 bar) on reserve.
The gauge, which serves as the changeover
indicator, is painted red from 0 to 35 psig
(0 to 2,4 bar). When the dial reads in the 0 to
35 psig (0 to 2,41 bar) range, it indicates that
the manifold has switched from the supply
to the reserve cylinder.

Introduction

The R600 Series second-stage regulators
are Underwriters Laboratories (UL) listed
designed to reduce the outlet pressure

from a rst-stage regulator, usually 10 psig

(0,7 bar) to 11-inches w.c. (27 mbar), in
domestic installations. Screened drip-lip
vent has standard orientation over the inlet
with other orientations available. Fisher®
second-stage regulators are painted palm

green for easy identication. The second-

stage R600 Series regulators are equipped
with stainless steel inlet screen to reduce the
amount of debris entering the regulator.

Types R622E and R652E 2-PSI Service Regulators

Re g u l a t o R s

Introduction

The Types R622E and R652E 2-PSI Service
Regulators are Underwriters Laboratories
(UL) listed regulators designed for 2-PSI
LP-Gas systems. These units are installed

downstream from a rst-stage regulator to

reduce an inlet pressure of 10 psig
(0,7 bar) to a nominal 2 psig (0,14 bar)
outlet pressure. The 2-PSI Service
Regulators are designed for domestic
applications that supply 2 psig (0,14 bar)
LP-Gas to a line regulator located inside
the building. In most cases a manifold is
used with corrugated stainless steel tubing
(CSST) as well as other acceptable piping
materials for routing to the line regulator.

These units have white closing caps for easy

identication of the 2 psig (0,14 bar) setting.

Screened drip-lip vents are oriented over the
inlet as standard.

VALVES AND RELIEF VALVES

In addition to LP-gas regulators, valves are required in most systems. Valve
functions in LP-gas applications include primary shutoff, excess flow, back
check, and relief. Internal valves are installed in the inlets or outlets of pressure
vessels in bulk plants, bulk transports, bobtails, and in in-line installations.
Internal valves provide: shutoff, excess flow, and back check functions. The
valves covered in this section can be operated remotely by lever, cable, or
pneumatic cylinder.

Excess flow check valves are designed to close when there is an excess
discharge, such as a break in a hose or line where the flow exceeds the valves’
spring rating. Check valves allow flow in one direction only while relief
valves open to release excess pressure. Manually operated shutoff valves can
be installed in convenient locations in a piping system.

Introduction

Fisher® brand valves, relief valves,
emergency shutoff valves, and globe and
angle valves are installed in the inlets and
outlets (liquid or vapor) of pressure vessels
and in piping systems to control the flow
of LP-Gas and NH
These valves are frequently used on bobtails,
transport truck tanks, large stationary storage
tanks, and in-line installations.

The valves provide a means of withdrawing
and filling product with or without pumps
and compressors. These valves may be
used as primary shutoff valves, excess
flow valves, and back check valves. Look
to Fisher brand for the latest in LP-Gas
regulator technology.
