Types of Regulators
There are two types of RHPS series pressure regulators
■ Pressure-reducing regulators with spring or dome loading
■ Back-pressure regulators with spring or dome loading
How a Pressure Regulator Works
A pressure regulator has a sensing element (piston or diaphragm) which, on one side, is subjected to a load force (FS) created by
a spring (as shown below) or a gas pressure. On the other side, the sensing element is subject to the force (F) of the system fluid.

Pressure reducing
std
The function of a pressure-reducing regulator is to reduce a
pressure and to keep this pressure as constant as possible
while the inlet pressure and the flow may vary. This is
accomplished by the fluid force (F) being equal to or slightly
lower than load force (FS) causing the poppet to open.

can either open in case of excess pressure or close when

Dependency—see supply pressure effect (SPE).
Droop—a decrease in outlet pressure caused by an
increase in flow rate to a pressure-reducing regulator.
Lockup—an increase in outlet pressure that occurs as the
flow rate is decreased to zero.
Self-venting—a feature that reduces outlet pressure in
a pressure-reducing regulator when the regulator set
point is decreased and there is no flow through the
regulator.
Sensitivity—the degree to which the regulator responds to
force balance changes.
Supply pressure effect (SPE)—the

Components
Every RHPS series pressure regulator has three common design components:
■ Loading mechanism (spring, dome, or combination spring and dome)
■ Sensing mechanism (diaphragm or piston)
■ Controlling mechanism (poppet)
Loading Mechanism
The loading mechanism is the component of the regulator that balances the force or pressure.
Spring-Loaded
Dome-Loaded
In a spring-loaded regulator, a coil spring is used to generate
a load (FS ) against the sensing mechanism. The amount of
spring force or load can be adjusted by turning the handle or
adjusting screw of the regulator.
In a dome-loaded regulator, a gas is fed into the dome
chamber above the sensing mechanism at a pressure
equal to or slightly above the required outlet pressure. This
volume of gas is used like a spring. The dome pressure (Fd )
is typically supplied by a second regulator called a pilot
regulator.

Combination Spring- and Dome-Loaded
The spring- and dome-loaded mechanisms can be used in combination with one another. The resulting effect provides the
function of a differential pressure regulator. This regulator is designed to control pressure which is the sum of a reference
pressure (provided by the dome) and a bias pressure (provided by the spring). See RD(H)6DP series on page 902 for details.

Sensing Mechanisms
Seat Design
The sensing mechanism is the component separating the
spring/dome force and the fluid force. It senses changes
in pressure and allows the regulator to react and to try to
restore the original set pressure.
The poppet within the RHPS series regulator can have a hard
or soft seat seal depending on the pressure requirements of
the application.
■
Diaphragm Sensing
piece of material usually made
of an elastomer, PTFE, or metal
depending on the application.
A diaphragm is normally
used for low control-pressure
applications in spring-loaded
regulators and in all domeloaded regulators.

BAR

used to regulate higher control
pressures than a spring-loaded
regulator with a diaphragm.

spikes.

Every RHPS series regulator is factory tested with nitrogen
or air. Shell testing is performed to a requirement of no
detectable leakage with a liquid leak detector.
Cleaning and Packaging
Every RHPS series regulator is cleaned and packaged in
accordance with Swagelok Standard Cleaning and Packaging
(SC-10) (MS-06-62), page 1174.
Cleaning and packaging to ensure compliance with product
cleanliness requirements stated in ASTM G93 Level C is
available.

RHPS series pressure regulators are not “Safety
Accessories” as defined in the Pressure Equipment
Directive 97/23/EC.
 Do not use the regulator as a shutoff device.

can release system fluid to atmosphere. Position the
self-vent hole or the threaded vent connection away
from operating personnel.

Pressure-Reducing, Spring-Loaded Regulators—RS Series
The RS series pressure-reducing regulators are suitable
for most gases and liquids. The RS series regulators
feature various poppet designs, a choice of sensing types
(diaphragm or piston), and seat and seal materials to
accommodate a variety of pressure, temperature, and flow
conditions.
The RSH series regulators are a high-pressure version of the
RS series regulators, and the LRS and LPRS series are lowpressure, high-accuracy versions of the RS series regulators.
The RS series regulators are available in sizes from 1/4 to 2 in.
with a choice of threaded or flange end connections.
Features
The RS series regulators are available with many options,
including a variety of gauge connection configurations,
self venting, internal filter, external feedback, antitamper,
special cleaning to ASTM G93 Level C, and NACE MR0175/
ISO 15156-compliant models.

Pressure-Reducing, Dome-Loaded and Air-Loaded Regulators—RD and RA Series
These pressure-reducing, dome-loaded and air-loaded
regulators are suitable for most gases and liquids, including
acids and oils. These regulators feature various poppet
designs, a pressure-sensing diaphragm (piston in RD2 series),
and a choice of seat and seal materials to accommodate a
variety of pressure, temperature, and flow conditions.
These regulators are available with a choice of threaded
end connections from 1/4 to 2 in., and with flange end
connections from 1/2 to 4 in.
The RDH series regulators are high-pressure versions of the
RD series regulators, and the LPRD series are low-pressure,
high-accuracy versions of the RD series regulators. The RA
series regulators are air-loaded regulators.
These regulators are available with many options, including a
variety of gauge connection configurations, a pilot regulator
(RD series only), external feedback (RD series only), special
cleaning to ASTM G93 Level C, and NACE MR0175/ISO
15156-compliant models.
Features
■ Dome-loaded and air-loaded
pressure control
■ Diaphragm sensing design except
RD2 series
■ 316L stainless steel materials of
construction for corrosion resistance
■ Maximum inlet pressure ratings:
1015 to 5800 psig (70.0 to 400 bar)
■ Outlet pressure control ranges:
Up to 0 to 5800 psig (0 to 400 bar)

Back-Pressure, Spring-Loaded Regulators—BS Series
The BS series back-pressure regulators are suitable for most
gases and liquids. The BS series regulators feature a choice
of sensing types (diaphragm or piston), and seat and seal
materials to accommodate a variety of pressure, temperature,
and flow conditions.
The BS series regulators are available in sizes from 1/4 to
1 1/2 in. with a choice of threaded or flange end connections.
Features
The BSH series regulators are high-pressure versions of the
BS series regulators, and the LBS series are low-pressure,
high-accuracy versions of the BS series regulators.
The BS series regulators are available with several options,
including a variety of gauge connection configurations,
antitamper, special cleaning to ASTM G93 Level C, and
NACE MR0175/ISO 15156-compliant models.
■ Spring-loaded pressure control
■ Diaphragm or piston sensing types
■ Blue knob or screw adjustment
■ 316L SS materials of construction for
corrosion resistance
■ Maximum inlet pressure rating:
507 to 10 150 psig (35.0 to 700 bar)
■ Inlet control pressure range:
Up to 0 to 10 150 psig (0 to 700 bar)
